Hello to all members, I bought this little amp after watching the preamplifier shoot-out and I'm very impressed with the way it sounds. However I'm always looking for ways to make this amp just a little bit better. With the schematics and pictures I show here, would somebody who is knowledgeable in electronics please suggest to me what is possible in this amp with compatable upgrades? I have upgraded the cosmetics of the amp and it looks much better than the stock product I think. I will post and apply links to the part's I used to do this, some parts are just a must have item. Like the tube base rings they really give that profesional look.
