    You have wrong information concerning the year Fender add the word “Dual” to the face plate, it was not in 1964, but 1966!!!!

    My ’66 Showman (chassis dated 1964) has exactly four (4) preamp tubes and four (4) power tubes. The effect circuit uses only one (1) tube.

    The first blonde heads originally had six (6) preamp tubes to support the 3-tube effect circuit and four (4) power tubes.

    Sitting in front of my ’65 Fender (Single) Showman, I count 2x 7025′ 1x 12AX7, 1x 12AT7 plus 4x 6L6.
    That’s fact.

    I have a 1965 Showman and a 1966 Showman, and I used to have a 1964 Dual Showman. RE: Tubes- Mar’ Himmerich is correct. Four 12AX7/7025s, four 6L6s. Dual Showman was made as early as 1964: Showman had an 8-ohm output transformer for a 1×15″ cabinet, Dual Showman had a 4-ohm output transformer for a 2×15″ cabinet. Fender occasionally got them wrong, as some have reported 4-ohm transformers in Showman, and vice-versa. I bought my 1965 Showman with its correct original 8-ohm transformer and its “matching” 4-ohm 2xi5″ cabinet! Due to years of being mismatched, the power tubes and sockets, grid load resistors, and speakers were pretty bad and barely functional. I had the speakers re-coned to 16 ohms (wired in parallel for a total load of 8 ohms), replaced tubes, sockets, grid load resistors and a few capacitors. That was about 18-19 years ago, and it’s still going strong!

    I forgot to add that Showman and Dual Showman were built concurrently; one did not replace the other.

    I have ’66. The 12AT7 is for the phase inverter and is part of the power supply circuit. 12AX7 is for the vibrato and does nothing for the sound other than oscillate. The 7025 are just old military (quieter) version of 12AX7. So 2 pre-amp tubes.

    Hallo,
    I have a Showman blond with the Factory No: A oo491.
    Could anybody tell me what was the production year.
    I bought the amp approx 1963- 64.
    It has the RCA 7355 Powertubes.
    After 50 years hidden it goes like new.
    I may have to replace one or two El-Condensers.

    thanks
    Claus

    Hello Claus,
    The 7355 power tube model of the Showman (and Twin) was a transitional model that was made from approximately September(?) 1963 until superseded no later than December ’63. One distinguishing characteristic of your amp should be the absence of the ‘middle’ knob on the 2nd channel (second channel will have volume ,treble, bass, speed, intensity knobs for a total of 5). If your amp still has the tube chart, there should be a two-letter ink stamp on it, first letter being ‘M’. The second letter is the month (‘A’ = January, ‘B’ = February, … ‘L’ = December).
    Also, on the top of the power transformer (black one on the far left as viewed from the rear of the amp), there should be some engraved codes; specifically “125P19A”, and “606327”.
