Weight: 100 lbs.
Speaker

  • Size: 1 x 12
  • Impedance: 8 ohms
  • Model: Showman 12: JBL D-120F ; Showman 15, Double Showman: JBL D-130F or JBL D-140F(For more info, check out the Jensen Replacement Speakers)

Effects: Tremolo
~Watts: 100 watts
Tubes

  • Pre amp: 6G14: 6 x 7025; 6G14-A: 2 x 12AX7, 4 x 7025
  • Power: 6G14: 4 x 6L6GC; 6G14-A: 4 x 5881

Bias: Fixed Bias
Rectifier: Solid State

Comments: The Showman 12, Showman 15, and Double Showman all used the same head with the only difference being the size and speakers of the the speaker cabinet. Maroon grilled Double Showmans exist, but are very rare. The harmonic vibrato tremolo circuit left half a dual triode (7025 or 12AX7) unused.

    The schematic of the 6G14 shows (6) 7025’s and (4) 6L6GC’s. The 6G14A shows 2 12AX7’s, 4 7025’s and (4) 6L6GC’s. The power output of these amps was 85 watts.

      Well, no. The 6G14 used four 6L6GCs while the 6G14-A used four 5881s. The output of either was reported by Fender to be 85 W.

    The 6G14 and 6G14A circuits are entirely different preamp topologies. The 6G14 Showman and 6G8 Twin employed the “James” preamp circuit. The latter circuit with the (A) signifier was the original precursor to the famous AB763 Blackface circuit.

    I’ve seen some with tapped tone controls. Which variation were these?

    Between the Tweed Twin with front facing controls, and the Blond Showman amplifiers, there were no less than 6 different output transformers used, with some obviously offering different impedance ratings, and others — who knows. Transformers for the twin were not used on the Showman and visa versa. Both the front control twin and debut Showman were introduced using 6L6GC tubes, with the A versions then going back to 5881 tubes (industrial 6L6GB). The different transformers were:

    1. Twin: 45268 and 45548. Now both of these obviously had 4Ω secondaries — and while the 45268 was used with tube rectifiers, BOTH were used with SS power supplies as well. So why two different transformers? Particularly because they started out with the 45268, went to the 45548, and then back to the 45268! And all while the output stage and speaker load was basically unchanged.

    2. Showman: Started with the 45550 (sister transformer to the Twin’s 45548, and invariably having an 8Ω secondary). Then the “A” version denotes using possibly a 45945, 45946, and (I believe) ended up with a 125A4A. I have seen reported that the 45946 was a 16Ω transformer, and the 125A4A an 8Ω transformer. But the 45945? Also, and I don’t mean anything by this, but there is sooooo much mis-information on the web about these amplifiers, that anything that is “reported” but I haven’t personally verified, I consider as unverified.

    I have personally seen all of these transformers but the 45548 and 45550. Of the whole bunch, all the others are physically quite large — nearly twice the size of the classic 125A29A and 125A30A transformers used in all the BF Showmans. There was even another set of transformers for the very rare Showmans built to use 7355 tubes — but those I have little interest in.

    So does anybody have any credible input as to:

    1. Why two transformers for the Twin that by all measures are otherwise the same? and

    2. Why four transformers for the Showman, when there’s only three possible output impedance levels that might be needed?

    The 45548 and 45550 transformers were the only transformers of the bunch specifying 6L6GC tubes. The rest specify 5881 tubes — but this is hardly any significant difference. The 6L6GC is simply a higher rated 5881, but with otherwise identical characteristics. And, ALL of these amplifiers were powered by the same 67233/123P7A power transformer, which ultimately determines how much power an amplifier can produce. Any input on the specifics of these Showman transformers, or why the twin had two different, but apparently identical transformers, would be appreciated!
