hi.
it was really expensive but i wanted to try the maximum (for me)...
about 1200 - 1400 in all the parts and tools.

12vdc computer 12cm fan over the heat-sinks.
Last time I checked, 290mvolts? It was easier on my 100 watt speakers, did sound really nice at 3.25mvdc with volume knob at 1\4 turn. Any higher, it wanted to blow-out my windows and added a couple of

Adjust for temp only if you have whimpy heat sinks. Normally adjust up slowly over say an hour or two up to max 325mv across the emitter resisters.

thank you for your replies...
i will do that after finishing my project to seperate the KSA-100 into two enclosures...
it´s more work than i thought. but than i will have a good temperature dissipation.

Hi All,
I own Krell KSA 100, it plays for a while and then goes in protection mode. Its not working now. I tried to on it after few hours but no sound. I just get thud sound when i turn off the switch.
Can anyone help me with trouble shooting or schematic.

Nishant

After several nights of reading the thread, I'm up to page 136 and I still don't have a very good idea of what it would take to build this amp. What happened to the wiki? Everyone seems to be pointing to it, but the web page is 404 now. Is there a list of suppliers for the transformers, heatsinks and a suitable chassis?
Hi Fenki,
congratulations on your wonderful looking amp.
It seems that you used 8 output pairs for each channel.
To do this, did you make any other changes to the circuit i.e. the driver stage?
What are the two inductors under the power supply board?
