I will never sell a tube that is below standard…… I have sold many tubes here on Ebay, and all my customers have been completely satisfied. I will work with you in good faith if there are any problems, or if you are unsatisfied in any way. I want your business now and in the future, so I assume you are the boss, and I am the employee. All tubes are tested for shorts, continuity, and emissions. I prefer PayPal. ALL CUSTOMERS PLEASE READ ALL NOTES BEFORE BUYING FROM ME !! 1.  RETURNS: It is my highest desire that you are completely satisfied with your purchase from me. I will bend over backwards to make sure that you are a happy customer. If anything you buy from me is less than satisfactory, message me BEFORE you either open a case or hit the “item not as described” button. Sound quality is tremendously SUBJECTIVE. For tubes returned for noise or sound quality of any kind you pay for the shipping we refund the purchase. We refund the price of the item NOT THE SHIPPING COST. If we sent the wrong tube we will of course pay for return shipping. For any tubes that are DOA we require that you send a us a picture of the shipping box to show us the damage. We test EVERY tube sent out and none should be DOA unless broken in shipping. 2.    PLEASE NOTE:  Tube silkscreen (lettering on the tubes) is VERY fragile. It can be wiped off and destroyed VERY easily. If you wipe off the silkscreen while handling the tube you diminish their value by up to 70%. DO NOT handle the tubes or hold them from the cylinder. ALWAYS hold them from the ENDS. If you are returning tubes and they are not in the same condition cosmetically I cannot give you a full refund. THIS IS VERY IMPORTANT. 3.  UNLESS YOU MAKE ARRANGEMENTS WITH US BEFORE YOU PURCHASE, YOU MUST PAY FOR ITEMS PURCHASED WITHIN 2 DAYS OR A CASE WILL BE OPENED FOR AN UNPAID ITEM!!! 4. TESTING: I test all tubes that I sell in one way or another, or I will state untested. I have a B&K 747 tube tester. This is a mutual conductance tester. It give a percentage value of gm for the tube under test and checks for shorts and grid emissions. I also use a Tektronix curve tracer for testing triodes. I give a number of evaluations for tubes. One evaluation is a screen shot of the tube with a high voltage applied to the plate. This helps the buyer see the linearity of the tube in question at the highest voltage the tube will see in a real circuit. The Curve tracer steps the triode through 10 gate/grid voltages starting with -10 volts and going to 0 volts. The lines show how the tube conducts throughout that range. At 0 volt the tube is at max conduction and is the top line on the display. It is easy at that point to take where that top line intersects the plate voltage, find the milliamp level and compare it to the datasheet. I give those numbers for you in the Item condition box. To further help the buyer I also include the Design values, for gm and ma readings in the table. This can then be compared to other tube sellers using inferior test methods such as Hickok,  Amplitrex, and other testers. The Tektronix curve tracer gives values within 3% of the actual value. The very best portable testers only can approach 10% accuracy.5.    Please note: The numbers given for gm are what I see on my tester. I DO NOT guarantee that you will see those numbers on your tester. I only guarantee that these tubes will test good, with no shorts, or gas, on a decent calibrated tester. I dont guarantee or imply anything else. 6. VERY IMPORTANT!!! Vintage tube testers almost always, due to age, have VERY LOW HEATER VOLTAGES!!!  Every tester I have ever bought is below 6 volts when selecting 6.3 volts. They average 5.8 volts. The voltage NEEDS to be 6.3 and 12.6. You can calibrate a vintage tube tester all you want. If the heater voltage is not right, you will NEVER get the right gm value. I have customers complain that their tubes are not the same as what I see on my tester. They say they have a calibrated tube tester. I have 40 tube testers. On all of them I have an outside regulated DC power supply that feeds the tube tester the correct heater voltage. 7. I dont check each and every tube for noise or tone. This is SUBJECTIVE and it is too time consuming. If you dont like the noise level or the tone we offer a hassle free refund policy.  International customers note: 1. Please wait for us to invoice you for the correct amount. If you have purchased more than one item, we must calculate how much the shipping will be. Shipping will be HIGHER due to insurance and shipping methods needed for expensive item totals. If you are buying only one item this will not be an issue. 2. Under no circumstances will we state on a US customs a declared value of less than the sale price. This is an honesty issue. We are honest with everyone to the best of our ability to do so. We want you to trust that what we say is true. There cannot be that trust, if we make false statements knowingly to anyone. If your country has tariffs/taxes so high that they cause large numbers of normally honest folks to make false statements, we urge you to work for change of those laws. 3 International buyers if you bought more than one item and want combined shipping it will ship in 2 days. 4. And all the Angels sang because the heavenly music was playing and it was turned all the way up.   Listing and template services provided by inkFrog

Here we have a NOS RCA JRC 1U4 Vacuum Tube Hickok Tested 100%+ New Old Stock and Hickok tested Please see pictures Thank you for looking Photos shown in this listing are of the actual item for sale.NO STOCK PHOTOS USED unless otherwise stated. Please have a look at the pictures for the cosmetic condition. Please realize when buying antique, vintage or used equipment that they cannot be in an absolute mint or absolute perfect condition, they might need some service, now or later. I take lots of pictures so you can see cosmetics. Use the zoom function and have a good look. It is impossible to describe every scratch, scuff or mark. So take a good look. That is what they are there for. We check and describe the as much of the functionality as we can. If not Fully tested , then items are not tested to the full extent and may have something wrong that I have not discovered. If Fully tested then that is what they are. Fully working. In photographs we occasionally use props to display items in the best light possible. These props, like my white board, lighting ,My Beautiful Wife (she is occasionally caught in the photos), kitchen table, Train track, boxes, my left or right hand are not including unless otherwise stated in the listing. ( Sorry for you having to read this but you would be surprised how many people think the items come with my table or a part of my anatomy and/or my Wifes legs that I have accidentally caught on camera.) Take it from me.... My Wife is not for sale and no amount of money would replace her, though if you offer enough I may include my one of my hands as this would get me out of doing some work. :o) In the first few lines you will see what you are bidding on, i.e... “This auction is for a ?????????? If it does not say base, stand , table , in either the main body of the description or title ... then they are NOT included in the sale. All our items, including changeable parts like bulbs, Vacuum Tubes, circuit boards, internal parts etc. are security marked. If you return an item these security marks are checked before refunds are given. I am sorry for having even to do this , but there are those out there that think it is clever to swap and change parts and return us a faulty item. We have them hidden throughout our items, including internal parts. These are there so we can identify if items have been removed, changed or tampered with when they are returned. VACUUM TUBE TESTING I do not Sell Just Passable Vacuum Tubes. All tubes purchased have loads of life left in them. Low and weak tubes are unceremoniously thrown in the nearest trash can, unless they are collectors Items. When using the word “Matched” it means in test results rather than in cosmetic looks. Whilst I endeavor to put tubes together from the same year and look the same, this is not always the case. I may have the same tube but from differing years matched up in test results, which means they may cosmetically or internally look a little different... The numbers/letters in parentheses are Equivalents put in to help people to find the correct tube. If it does not say MATCHED then please do not consider them to be such. I use a TV7/U military spec Tester which is calibrated . I have 4 of these machines and all display a slightly differing value if I test the same tube, as two testers are never the same. So this shows what I get, and what you get may be slightly different. So all test results are a guide only.I also use a Hickok 752 /800/600 or Amplitrex AT1000 for testing All tubes have passed the Gas and short tests. Rectifiers and Diode tubes do not have Transconductance values. IF YOURE UNHAPPY WITH AN ITEM ...Contact us via messaging.I am human... I make mistakes once in a while. I Run this store on eBay. I am not a huge retail outlet. I try to resolve any issue to both our best interests. MAILING I Try to Mail out within 24 hours of your payment. Where I live the Post office is closed on a Saturday, so Purchases paid for on a Friday will go out on Monday as I work Fridays and do not get home until after the PO is closed. RETURNSI accept returns unless stated otherwise in the description. We insure everything, and we have to pay for this insurance. I also pack well. If you still receive an item that has been damaged please let us know so we can start an insurance claim. Take plenty of pictures and send them to us as this helps alot.I may ask you to return or keep the item whilst the insurance goes though. If I ask you to return it then I will refund you in full once it is returned.. If I ask you to keep the item , then you will be refunded once the insurance goes through.I think it is only fair to ask the carrier responsible for the damage to pay for it.

The 1L6 and the 50A1 voltage regulator tube for the 600 series not included. If you own a 1950 G500, let me know and I will substitute the correct 1S5 for the 1U5 but may not be Raytheon brand. The tubes have been tested for new performance and they are factory fresh. I will properly package the tubes in a box for safe shipment and pay USPS postage with tracking number in the US. Same business day shipping. International shipment through US Postal Service International for actual postage cost and actual selling price stated on the customs declaration. 7 ounces packed for international shipment.

Item is one unmatched lot of GE and Motorola 1U4 vacuum tubes. These tubes are used and have dust, shadowing or label discoloration that appear with extended use. However, they are clean and test strongly and will perform well for a long time. These tubes and have been tested and are good. All tested tubes are at least GOOD on my Superior Instrument tube tester (most 7, 8 or 9 pin tubes) or meet the minimum strength on my U-Test-Em drug store tester (most other tubes). If a tube is labelled as untested, it is because I do not have the necesssary equipment to test it. All tubes that dont meet your expectations can be returned regardless of their test status. Sets of vacuum tubes labelled as pairs, quartets, sets, etc, came to me grouped together or labelled as such. My tube testers are not sophisticated enough to guarantee that all sets of tubes are fully matched correctly. Again, if you are unsatisfied with the tubes you receive, you can send them back for a refund. --> All items are inspected to ensure that they ship in working order ready to use. Any damage or wear outside of that which comes from normal usage is noted above in the description.
