I only joke 94.7% of the time.

Slowly coming together! I have spent way too much time on this project! So many modifications to this amp. Initially I dipped the...

With a little help from my friends, I was pointed to C8 on page 4. It is a 2.2 ufd film cap. I bypassed it with a 20 ufd film cap...

On page 4 of the schematic, there is a SERVO/HIGH PASS section but I am unclear as to which cap (or resistor?) could be changed to...

The next dilemma is a built in high pass filter in the Crest. I have noticed a distinct improvement in the extreme low frequency...

An update on the Crest catastrophe; The caps from China came in and of course they measure 15,000 ufd instead of 18,000. I could...

What about removing / moving / changing the value of R 10 and R 12 on the fan driver board (page 2) The connection of Q 3 and Q 4...

So back to the fan issue. I have discovered the location of the temp sensors. The blank terminals must be for use with a different...

Getting in over my head---again. I have been using a Peavey GPS 3500 (about 600 WPC / 8 ohms) and it sounds great. Bass sounds...

Hi Jim, they are 24 Volt fans but the series trick would still work. I have just discovered this morning that this amp does not have...

J4 on the schematic is supposed to be connected to some sort of 3-pinned temp sensor presumably on the heat sink.

Further puzzlements, the manual says fans are governed by heat sink temperature but I have never heard the fans 'rev up' on start-up...

Too late, they're on their way...

I think it has a hard life with Peter LOL

That's funny Glen! But I have to confess that the clip lights have flashed on a few occasions. Pink Loyd on the 150" screen can get me...
