Selling due to upgrade to different solution with all tube I/V conversion. This converter have very balanced sound, great timbre and deep base. Original price was abour 330USD. There are P605A germanium transistors in power supply. I/V conversion transistors is special KT602. Main tube is 5687 - best one, 5 stars from GE. Used lightly about 500h. And EZ81 rectifier from Tungsram, also 500h. Supply is 230V AC (not 110V !!!). Size od PCB is 16x16cm, height 9cm. This converter is ONLY for TDA1543 (!!).

T.S. 5687 Vacuum Tubes For sale I have a pair of Tung Sol 5687 vacuum tubes. Great pair of an excellent tube. Tubes carefully tested for transconductance, shorts, gas, life and leakage. No tube is sold that has any gas, leakage or fails life and strength tests. Photo is of the actual tubes on auction. I take a great deal of pride in the honesty of my representation and the quality of my customer service. There will be no unwelcome surprises with my tubes....guaranteed. Test Results: 5900/6600 and 6800/6700 gm (Triplett 3444) Minimum: 3500/3500 gm (Triplett 3444) Test Equipment: Hickok 539C w/ Fluke 73III multimeter Triplett 3444 Hickok KS-15874-L2 Cardmatic Maxi Matcher w/ Sola CVS Regulated Power Supply The Hickok 539C is a highly regarded transconductance tester. The Triplett 3444 is one of the finest testers ever made. Exceptional in every aspect. Superb with directly heated triodes. The Hickok KS 15874-L2 is a commercial version of the wonderful 118 Cardmatic. In my opinion, and the opinion of many tester experts, this is the best tester that was made by Hickok. A real gem. The Maxi-Matcher is a useful tester for measuring current draw and transconductance at 325/400 plate volts with 5 bias voltage settings. Very good with 6V6s and EL84s, this tester falls a bit short of true operating levels on 6550s, EL34s, 5881s and 7027s. Still much better than most suitcase testers for measuring power pentodes. I do not trust the minimums on this tester and they are therefore not listed. The industry standard by default. ALL of my testers (except Maxi) have been calibrated and redone by Chris Haedt. ===== Fully Guaranteed! ===== Money back on these tubes if they do not operate and test as described! ALL my items on eBay are genuine, authentic and original. As with all of my auctions, authenticity is assured so please feel free to bid with confidence! Shipping: U.S./Canada: FREE First Class / Ebay International: $ Ebay All tubes shipped within 24 hours of payment verification. Tubes are shipped upright, in oversized boxes with packing peanuts and bubble wrap. Additionally, I insert filler in each tube box to prevent movement of the tube within the box.

1) Sylvania 5687 Gold Pin Tube (used in Audio Note, Modwright, Consonance, etc.) Lot #215 One (1) tested tube(see Gm measurement in pictures) from an estate. I had them professionally tested by a technician on a calibrated Hickok 539C using full voltage on the plate; checked for shorts, gas, and leaks. Top getters. (Measurement basis @ 4800 for reject). Unusable tubes from the estate were tossed out - listed tubes are guaranteed to be good (actual readings can vary by tester of course). Tube(s) you see will be the one(s) you receive. Many more tube listings to come. Flat rate shipping CONUS.

CARTE DALIMENTATION RSAG7.820.5687/R0H POUR TV HISENSE H43NEC5200 TESTER

Item is one unmatched lot of RCA 5687 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.

I do combine S&H

Up for auction are 3 NOS/NIB General Electric black plate 5687 audio vacuum tubes. All three tubes would make a super nice addition to anyones collection or to use either one. All three tubes were tested on my TV-7 tester where 38 is the required minimum and all three tubes had no leaks or shorts. Please, look at the above pictures for test scores as well as the overall cosmetic condition of each tube. Thanks For Looking! No International Shipping!!!
