#3. The amp is +/- 24 volts. Victoria magnetics 400VA 19vac transformer. 112,000 uf of caps per rail. The MOSFET's are IRFP260 so there are half as many. Boards are Brian GT's from Dale. The rest is left over from other projects.

How long have you been standing there posing with your amp?

Or is it the sun that made your face red?

Looks like a very nice and heavy peace of work!
I like the plexy on the 3 sides.
What's the one black side made off?
And most of all, how does it sound? Like Like Peanut Butter and Chocolate?

Greetings

It was the sun. People kept rolling me back into the water. The black side is another heatsink. It sounds great. That's why it is the best.

Hi Mark!
My congratulatoins, it’s great!
I see, you also have a problem with your foots when you take a picture? (at #3)

Is there any problem with temperature of heatsinks? Are they at the same temperature? Haw I could see, irfp240's of one channel participate two diferent hestsinks.

The heatsinks are only about 45 Degrees. They are very close to the same temperature.

Hi! Mike what did you use to cut the hole on the flexiglass where the cap is mounted. I'm thinking of doing the same thing don't have to buy clamps.
