1 1/2 tube reverb
« on: November 19, 2010, 02:53:50 am »
Hi guys, Got a spare 1/2 12AX7 and not sure what to do with it. Looking for some more info if it was added to the 1 tube reverb. Is it as easy as this schem. Thanks

That's the idea. But I'd Make V4 a 12AT7, connect it parallel exactly like Fender did, and drive the tank . I'd use the extra 1/2 12AX7 for recovery.
A schematic, layout, and hi-rez pics are very useful for troubleshooting your amp. Don't wait to be asked. JUST DO IT!
