No worries, I've now found a larger case that will give me around 8cm between chips and toroid, so I'll probably go with that.

Hi

I built a couple of these last year. I experience a high pop in the speakers when I turn off the gainclones. Any information about this?

Unfortunately, we arent able to search just this thread So Im about to ask a question that has probably been asked a few times before in this thread (Sorry! It will take a week to read through the whole thing)

I have a ground loop hum issue.

I built the LM4780 4 channel version wth two amp boards. ( 2 channels off each board and one transformer).I followed the directions and did the star ground. My RCA's are isolated from the chassis with plastic isolation washers. When I have my PC connected via RCA as a source to the amp, I get alot of hum, even at low volumes. If I disconect the power cord from the PC and run just off the battery the hum goes away instantly. Is there a modification I can make to the amp to eliminate this issue?

Sounds fantastc when its not humming!

Did you use both rectifier boards or just one as recommended?

Is your star ground as described here: Commercial Gainclone kit- building instructions

Yessir, one rectifier board as you suggested. And yes to the star ground model as well.
