And people keep telling me caps last forever. Not so.

Wow, 6 pairs of outputs.

Update to close out an old thread.
I did replace all of the electrolytics (NP and standard) as Bigskyaudio suggested on that board.
While I was there I also swapped out all of the resistors that looked baked.
I went with bigger resistors also, the 2Ws I replaced with 3Ws, 1W with 2W etc..
For the 2W ones by the XLRs that looked cooked and baked the board, I also mounted them about 1/4" up off the board and put insulator (stripped wire jacket) around their stilt legs.
I figured giving them some room to breathe might also help in heat dissipation.
Bottom line, it now does wait a few seconds before it comes out of standby mode as it should.
It is very quiet, no hum or noise from amp or speakers, and sounds great.
Thanks again.

Nice.
Tells us how much there can be accomplished when one turns to some friends for help.

And for Our Greek friend just above You here: Who gave you ever the idea that Caps are forever? (Caps here: Electrolytic aluminium Capasitors) WAY off.

Nice amp Muddler.

Hi,

I own a Parasound HCA-2200 (1st version) since 1994 which has one channel,
can't remember left or right that makes a very LOUD sound on power up. It happened
immediately unlike when it is running as it should be.

Causes: a faulty tube pre-amp which let out very signal into my parasound which
blow off both my speaker woofer instant.

I didn't have it repair till today because i don't know much on electronics. The set still
run fine except for the start up "poh" sound.

I hope to get it repair by myself, or someone can guide me to which component
might be burn.

Apologies up front for my lack of knowledge; I am a novice with electronics. The following info may give a clue to someone who knows what there doing. Some of this info maybe be relevant and some extraneous.
