Ripping apart my Peachtree amp for mods?

post #1 of 4
Thread Starter 

I'd love to get some mods into my Peachtree but to be honest, I'm not electrically knowledgeable enough to know what components to swap. I'm already looking at an opamp mod but I'd like to know if there are any cap upgrades etc I can do. Would an experienced DIYer be able to spot what I can upgrade if I post a pic of the PCB? Or should I be content with upgrading opamps?

OK So here are the mods I would like to perform:

At least some of them, whatever I'm capable of. I will shortly post a pic of my amp's bare chassis, please let me know if you can identify the parts he's talking about on the board.

Most of the so called 'upgrades' on that list is questionable. I'd only look at the tubes and the opamp in that list. You can buy the tubes off ebay and the opamp from mouser or digikey. Just unplug and replace when the unit is powered off. Have fun!

You think so? The tube does nothing in the circuit, I've tried that upgrade before. So just stick with opamps?

Also, what about these mods? I'm skeptical for the simple fact that adding "power conditioning" adds another $400 to the job.. but do they have any good ideas?

Does ANYONE think that cap upgrades are a good idea? If so, recommend some caps?
