Re: Need help with Vox AC4 top boost ideas

Got it. Never seen a schematic without a tube rectifier. Thanks!

Re: Need help with Vox AC4 top boost ideas

Also, dumb question. Where is the rectifier on the schematic and layout? I can only find the EL84 and two 12AX7's.

Re: Need help with Vox AC4 top boost ideas

Interesting. You might as well just do an AC15 in that case. Probably more useful for you. I'm just looking for something to mess around with at home. Is the last schematic and layout you posted the final version of your AC4 amp, aside from tweaking the value of the Cathode caps?

Re: Need help with Vox AC4 top boost ideas

Any updates to this amp? I'm a newbie around here and am kinda interested in building a top boost AC4 for home with a Celestion blue. This version uses two 12AX7's I assume?
