So along time ago -- like last summer I soldered the kits together and have since then been sitting at home while I was at College (Ohio State University -- I'm a freshman now yay) Well now that I'm home I would like to complete these little gainclones and I was wondering what else should be done asides from the parts that were included to make these amps operational. I know I still need a chasis/heatsink/fuses -- I intend to have a 6ch gainclone in the end for 5.1 use and already have 2x 625 VA +-25V swing with dual secondaries. The volume will be controlled via my computer so no POTs are needed. Basically I'm asking for recommendations of what to do to this gainclone -- Does it need a zobel (of what values) any other circuits or filters? How big of a fuse is needed to keep those massive inrush currents on powerup from blowing the fuse?
This will be my first AMP project and for right now I'm only concerned with getting 2 channels operational and from there I'll worry about any advances such as the high capacitance unregulated mod later, I would however like to know about any other advances since I haven’t been checking the board recently.
The kit I have is the BrianGT Rev B. board -- 1 premium kit and 2 basic kits however I'm missing a pack of resistors so at the moment I can only possibly get 4ch operational.
Thanks for any input

Hi Dylan,
since you plan to use them for home theater, I recommend you a lot to check the following threads:
- The (high-cap.) unregulated PSU for chipamps (started by carlosfm)
for the reason that you will need the "POWER" and "ATTACK" for home theater...
- I'm sorry, but the amp needs a zobel (started by carlosfm)
- Zobel network.....Better bass? Yes or No (started by HawkeyeStoob)
for the reason that most probably you will long cables run for the setup... which will increase the possibility of the LM chip to oscillate...
REgards,
