National, Valco, Supro Amplifier Products. Some earlier Fender models used a 12AX7 or 12AX7 for the phase inverter--recommend a good-quality tube for such amps (12AT7s will usually work as well). Fender had tremolo or vibrato on some amps. Second tube is second channel preamp, 7025 is specified. Consideration and exceptions: Source-date codes weren t an industry standard until after WWII. Also it s worth mentioning: Sometimes there is a space or hyphen between the manuafacturer code and the year/week code. Reissue amps also use stamped Date Codes. This is especially helpful on (less popular) gear that doesn`t have reliable serial#`s or other information to date them. This tube does not need to be low in noise, however it should have good quality cathodes in order to handle the load.
Note: early versions of the Tremolux 6G9A used 6BQ5/EL84 tubes instead of 6L6GCs. Some technicians recommend NOS GE 7025WAs, which are still available. Vibrolux models 6G9A, 6G9B, 6G11, 6G11A; Tremolux 6G9A First tube is first channel preamp, 7025 is specified. If the amp has tremolo or vibrato, it will have at least one extra tube, usually a 12AX7. Most Fenders from 1966 to 1969 have 1966 dated CTS pots. Note: Since this article was written Tung-Sol, Electro Harmonix and JJ Electronics have released 6V6 tubes suitable for high plate voltages making them a great option for these amps. Preferred Series 7025 and Tung-Sol 12AX7 are suitable. This tube need not be low-noise or nonmicrophonic. DO NOT try to use 6V6s, 6550s, KT88s or EL34s.
Found as second stamping on speakers as a date code 550XXX from 1947 through the 50 s and 60 s (all the 1940 s amps are generally field coil Rola spkrs) dating rola speakers. Left: The source-date code (285709) on a speaker. It s worth mentioning since a lot of people rely on pot dates.sites for free membership on sex chat sites.
. Because this tube amplifies the signal from a reverb spring (which is inherently microphonic), a really quiet tube is not really needed. If the heater shorts to a cathode in this tube, the amp will not work properly. ANY 12AX7 type is suitable here--it is NOT critical, becase this tube is not in the signal path, it serves only as a modulator. If less gain is required, an NOS 5751 is suggested. If you see any data that is not listed here or notice any errors, for 1970â€™s and earlier Fender amps, please send us an email and we will update the chart. .
