An externally hosted image should be here but it was not working when we last tested it.

Here is a mono power amp board I designed a few years ago, depending upon outpet devices and power supply voltage rails, it will deliver up to 200W into 8 ohms with very little distortion.

Are those boards the same? I ask this because I am not sure, but it looks like on one board the output transistors are one way and on the other board is different.

Maybe he didn't fire it up yet... Outch!
Hi there all
Theres some fantastic looking amps in this thread, my next project after ive finished my DAC will be a big amp. (im only a newbie)
This was my first project i ever did, a half assembled Velleman K4020 kit i had given a month back.
Regards James

TO-3 SymAsym
I had an extra set of SymAsym boards and I decided to use them to rebuild an old amplifier. The layout is a bit unfortunate, but workable. Since the heatsink assembly was made for TO-3 transistors, I chose to use a set of 2ST2121/5949 outputs. The amplifier is unconditionally stable and has a 450kHz bandwidth.
Here we are, work in progress.
