Planning single channel 6g4a

[bullkelp]

I’ve ordered a blonde bassman chassis and undrilled face plate, hanmond iron and have my usual 2mm g10 and turrets.

My plan is a 6g4a harmonic trem single channel head in brown with my usual tiki grill emblem etc

My question for the gurus here:


Given they I’ve built quite a few fender amps to schematic spec , and I have a couple original browns , if I was to make such an amp, what specific mods would you recommend?

I like to play surf music (clean and fairly loud) but also like to noodle
With p90s and jazz boxes with warm smooth tone. I like to use an attenuator and get smooth drive. One thing fenders can suffer from is fizz. So some advice about minimising that would be great.

Otherwise I’m happy to build it to stock (sans one channel).

Many thanks

I'm far from a guru, but I am a fan of playing surf, so your plan sounds great. If I was building that amp, the things I would do are maybe add a mid pot and a negative feedback switch.

Sounds like a 6G4A without the normal channel. No other changes needed I'd say. Once you get it running, you could just mess around with the V1 preamp gain a bit if it's not clean enough.


(FWIW, a mid pot would just entail replacing the 6k8 resistor with a 10k pot)

Here's how I replaced the CF-triode with a mosfet in my last harmonic trem build. That way you could get away with 4 preamp tubes.

EDIT: I think I drew the intensity pot backwards.
