Master Volume for AB763 lite
« on: July 28, 2016, 10:16:53 am »
I want to add a pre pi MV to my AB763. I built it per Sluckey's design with the exception that I do not have R14 installed. do have C6 coupling cap and R13. Would it matter if in put the pot before or after R13. Putting it between C6 and R13 makes the wiring a lot simpler. Tks.

you could probably make R14 a pot, say 500K and see how it works, if it's always on 10, replace it with a fixed R.
Went Class C for efficiency

I used a 100K pot on my TDR...

BTW, the link you posted points to a file on your own computer. It's not available to us.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
