Tested on a fully restored TV7-DU, by Dan Nelson, pictures of evidence for this included in the listing. It was restored and calibrated on October 21st 2021. Tubes are tested for shorts. PC= Plate Current DC= Date Code Please note, TV7 data minimum is equal to 60%. For example, (insert model number here) min value 60. If the tube tests at minimum 60, that is equal to 60%. The number over (/) is the minimum test data result as described in the TV7 DU tube testing manual. So 60/ (min) 60 = 60% Genuine NOS, the boxes have some damage Tube 1 DC=4A8 54.5/32 PC=5.959/32 PC=6.4 Tube 2 DC= 3B8 58.5/32 PC= 6.456.4/32 PC= 6.2 I mark all my tubes, so please dont waste your time seeking to send me back your old dead tubes. All testers read differently. I have sought to have my tester as accurate as possible. I will not be giving partial refunds because you have received different test result. All tubes will be shipped well, an example of how I pack is pictured in the listing. (obviously these tubes are not included) I wont be lying on a customs form I combine shipping. If the tubes are of significant value, the postage will be extra due to insurance.

A Soviet era 6H9C 6SL7 ECC35 valve with spot welded gray plates, silver rods, clear top and filled crescent getter. THe valve is aslo marked 1282, OYK 3 and XII 82. Tested very good. The valve has been tested on the Amplitrex AT1000 and the test results are shown in the photos. Please read the condition section as this forms part of the description. Unpacked weight is 0.030 kg. Note on the gas test reading from the user manual for the tester:In the case of small pre-amp valves anything more the 0.1 milliampere will likely cause problems. With a power tube the interpretation must be different. Power tubes typically show a few milliamperes of gas induced current increase, even if they are good. This is because in these tubes, plate temperatures are generally much higher and there is more surface area on the plate and other tube components which naturally outgas somewhat as it heats up. Also, because these tubes operate with several tens of milliamperes, or even over 100 milliamperes, a few mA of gas current is ok. With power tubes, a gas-induced current increase of less than 10% of normal plate current is ok in most application circuits. For UK Shipping. Please note shipping in the UK where possible will be using Royal Mail. However, due to the new size restrictions implemented by the Royal Mail which has resulted in very large increases in P&P costs for certain items, they will be shipped via courier using a drop centre which will increase the delivery time. For Overseas Shipping. The item will be shipped Signed For for overseas. Packages weighing over 2kg will be sent via International Signed For Courier. Combined postage is offered on all items and is based on the packed weight. Shipping costs for all returns are at the Buyers cost unless the item was misdescribed in the original listing or this was not covered in a subsequent question or revision to the listing. Overseas bidders are responsible for settling any Customs Duties or Fees on items they purchase.
