Title: Hammond_A035 wiring diagram
Post by: Garth gilmour on December 30, 2021, 07:24:55 pm

I'm new to amp building and my schematic reading skills are not up to par, I'm currently converting a hammond A035 to a guitar amp, I'm looking for a point to point wiring diagram, I have input output and power sections done, I want install volume and tone stack, any help would be greatly appreciated,

Your details are very lacking. Here's one successful AO-35 conversion by Dr. Z. It's called Carmen Ghia. Maybe you can use some of this to finish your conversion.

Thanks again, I even contacted DR Z about converting the amp for me, since I live 40 miles from his shop said he couldn't help me, that's why I doing it myself

Here is another link on the subject http://revolutiondeux.blogspot.com/2012/01/dr-z-amps-carmen-ghia.html (http://revolutiondeux.blogspot.com/2012/01/dr-z-amps-carmen-ghia.html) It is a small tight chassis. Difficult to work on and to get the noise down. So some (like me) rob the trannies and a few other parts and start with a new chassis.
Another amp that originated with that chassis is the Goodsell Super 17. I don't know if there is a reliable schematic for that amp.
