I want to try building one of the kits from chipamp, but i dont know where to find a transformer or chasis or heatsinks, as they're not included. What transformer would you reccommend, and where can you find it.

I just found this site and am eager to comment on my rig. I'll spare you the effects before the amp.
first its a Crate GFX 15 practice amp which i run at full volume for distortion, the headphone out is sent to a transformer that i salvaged from the power supply from some computer speakers and a potentiometer as a master volume. This is all sent to a BBE 822 sonic maximizer which goes to the effects return of a Carvin SX-200 combo amp.
You got all that?
I really like the tone of set-up but i was just wondering if this is in some way bad for the amplifiers involved. I've been using this set-up (minus the BBE) for atleast 4 months.
