5F6A Bassman Amp Clone

[steveneddy]

Here is my version of the Bassman that my company Deadwood Amps manufactures.

I have enjoyed working with the turret boards because I can get components more compact and work with five levels of necessary.

This amp is very quiet and sounds great - punchy and full of great tone - especially when you turn it up past 6!

Enjoy!

Welcome to AmpGarage. Nice to meet a fellow Texan that has a thing for 5F6As.

I'm curious, what are you running the plates at and how's your bias set? And any chance for clips?

Here's the amp at a gig

Thanks - I really love the sound of a well build 5F6A - something about that circuit and 4x10's just sounds great to me. 12AU7 in V1 for blues night - 12AX7 for Rock night with a little pedal to push it into overdrive bliss.

I remember nothing about the specs once I built it. Sorry.

But everything is very close to stock settings - nothing out of the ordinary going from memory.

I guess I could open it up and measure a few things I you were that interested.

I'll attempt to get some clips up soon.

What would you consider stock settings?

As I recall - 450-500 Volts at the plates and 42-48 mv bias - 48 volts on the bias circuit - I think.


The only out of the ordinary thing we do different is that we jump the input pins at V1 to you can plug one guitar in without having to jump the inputs - which is what most people do anyway - we just jump it at the pin for convenience.

One mod I have been toying with is to give the second side of V1 it's own cathode ground and alter it for increased gain - then using an AB pedal to switch between a clean and "dirty" channel. You could have individual control of both "channels" this way. Also the player could put a dirty pedal on the second channel only - so there wasn't a signal loss when playing through the "clean" channel.

But then I "discovered" the 12DW7 tube - and I wire the circuit with the B side of the tube and the A side of the tube reversed - to the player can have a lower gain in the volume control on the end - and the second or bright volume has the higher gain section of the tube - and when you use your AB pedal to switch between them you have an easy clean low gain/dirty high gain setting for each channel - and no batteries to wear out on the dirty pedal and still get a "channel switcher" amp - poor man's way.

Of course - this means you can't jump the tube - but we can make the amp any way the player requests. And the DW tube in the V1 socket can give you some interesting options for the player.

Wow - I must have been chatty this morning.
