MATCHED PAIR (2) SYLVANIA 6BQ5 EL84 BLACK PLATE RED TIP LIGHT USE. RED TIP TESTS WITHIN 2% OF MUTUAL CONDUCTANCE BLACK PLATE 95% LIFE SAME DATE CODE All tubes are fully tested for leakage, shorts, gas, life, and mutual conductance. Then they are matched according to brand, properties within the date of production, and mutual conductance. Matches are based on mutual conductance. I use two different, calibrated Hickok 539CS and/or, a Weston model 981 type 3. If they pass the testing, they will be sold with test data for that tube. If the tubes arent matched within 6%, I will acknowledge that in the description. I also offer a money back guarantee. Buyer pays return shipping for local pickups, I advise you to bring the electronics that the tubes are going in, within reason. Guitar amps, small radios, etc. I will allow you to test them on site, but you will be responsible for any product damaged by a faulty electronic. Im an honest seller and I stand by my product. Feel free to message me with questions. GlassBatman8 T.5

This tester applies test conditions for this tube (including the precise filament voltage) and then measures transconductance (gm) in accordance with the engineering definition of gm. Tubes may also be operated under the test conditions for extended periods to be sure that it is stable. A tube must be tested in this manner to compare its test results with the manufacturer’s original intent or with other tubes of the same type. Most tube testers do not apply the test conditions required or conduct a valid gm test. For more details on the test and our test equipment, please contact us.

sie bieten auf: Grundig NF 2 Endstufe Röhrenverstärker Baujahr 1959 die berühmte Grundig NF2 ist mittlerweile ein echter Klassiker. Ursprünglich zum Einbau in Musikmöbel und zum Betrieb mit den Einbau-Tuner-Vorverstärkern HF10 u.a. gedacht, ist sie heute unter HiFi Kennern begehrt und geschätzt. Die Schaltung ist ein klassischer Gegentaktentwurf mit 2 x 2 x EL84 und 2 x ECC83. (klassischer gehts schon gar nicht.) Der Aufbau ist in Fränkischer Tradition grundsolide, stabil, betriebssicher und wertig verarbeitet. Es handelt sich hier um das selten frühe Modell mit Drossel in der Spannungsversorgung: Die früheste NF2 (die noch nicht so hieß) war für den Betrieb ohne Abdeckung konzipiert worden. So wurden Sicherung und Stromanschluss von Hinten innen und nicht gefährlich offen auf der Oberseite montiert (siehe rechts) wie bei den späten Modellen. Diese späteren NF2 / NF20 hatten dann auch Oktal-Fassungen zum Anschluss des Radios und der Lautsprecher, während das frühe Stereo-Endstufen-Chassis mit äußerst seltsamen 9-Pol-Fassungen aufwartete. Zustand: funktioniert - gebraucht - überholt Gerät wurde in den 1970ern schon mal repariert (Gleichrichter BY 127) Die Elektrolyt Kondensatoren wurden 2022 alle gegen neue Elektrolyt ausgetauscht. Die Heiz- und Anodenspannung wurde sorgfältig auf die notwendigen Werte angepasst. der Arbeitspunkt der Endröhren wurde überprüft und ist eingestellt. Anstecken und geniessen . die Endstufenröhren EL84 und die Vorstufenröhren sind enthalten.

Up for auction is a set of Reflector 6n14n-k (EL84, 6BQ5) Quad. These were purchased a few years ago from a Ukrainian supplier selling as a matched quad before the war. I sold my mono blocks that I had occasionally used them for, and now I have no need for them. Biased in at 25mas, these are said to give several more watts over the standard EL84. When I played them they sounded very good with tight bass and nice mids and highs. I had purchased these as a used matched quad. Unfortunately, my tester cannot test these tubes, therefore, I am selling them as a quad. Dates on tubes are: 73, 74, 75, 75. The seller I had purchased them from had a pretty good reputation for items as described and positive feedback rating. Please check out other tubes that I will be listing. All items will be shipped USPS within one business day upon payment. Thanks for checking them out, and good luck bidding! Sincerely, Gr8Cats
