Just sold my last Frank head. My new faves are the A models with the 2 circuit breakers on either side of the polarity off/ on switch. I don't know what it is but to my ears they have something sweet sounding all across the tone spectrum that even the Franks can't match. The B models sound steril to me so I won't even compare those. I have one 745PA that I converted to a 2 channel amp with high and low inputs and another that would be an A3 (left channel has vol,treble,bass,bright switch and right has harmonic clipper/ selective boost)but these models had speaker configuration model numbers. My 745 has a metalic face and the A3 has plexi. I thought all the early A's had metalic faces but not this A3 with circuit breakers. I had a B4 with the whole shebang but the lack of tone caused me to sell it. I use an Art M1 reverb unit and a Boss trem unit so I don't miss Kustom's washed out reverb although I love their tremelo. Just thought I'd throw this out cause there's never much discussion on these models with the circuit breakers. This is strange to me as the 67' catalog in the literature section of this site shows a hole slew of them. They don't come up for sale very often mabe because the circuit breaker A's were a short lived model and they switched to the fused A's producing more of them. Does anybody know the timeline on these?

Unless they changed the preamp boards in some major way between the A and B series, the power amps are only a few minor components apart. I am going to modify an A unit to match the B unit I already have and it will need 2 or 3 minor changes and they will be the same.

It's got to be those white Mallory caps. They used them on the early A models with the circuit breakers on either side of the on/off polarity switch. I don't know about the later A models that actually had the A designation. I thought I could get the John Fogerty tone(not talent)with my B4 but low and behold with my A3 I can! This is the circuit breaker model so I think his amps must have had the white mallory caps because he used A4 heads. The very thing the Bud deemed unreliable are the key to tone (I think) That's why the Franks sound so good. You wont find them on the B models, hence the bland tone. That's the difference in the preamp boards. Just my theory.
