Here is a picture of my Legacy GC converted to use new snubber PS.

Enjoy,
Pete

Great, but those 'heatsinks' are too thin...

Dimensions are one eigth inch thick by 6" by 3.5" Had it cranked for about 30 minutes and did not even get close to warm. They cam out of an old dynaco st120.

Hi Pete,

How would you describe the differences between the two configurations?

Dave

Depends on the voltage though.. If hes running it at 10-20V the thing wont even get warm.

Plus it kinda connects to the chassi.

Yes, at lower voltages it won't get hot.

If the heatsink is thin there will be a "hot-spot" right on the back of the chip. The heat doesn't spread properly.
The heatsink will be almost cold at the extremes, and

on the chip. Even if it's connected to the chassis.

As long as the SPiKe protection doesn't trigger it's alright, no need to worry but in general it's better to have as low temperatures as possible if it's a question of the life time.

Opppps Tranny is 25-0-25. I have 37v coming out of the PS board. Looks like I need to rethink my heat sinks real quick.

Thanks for the info,

Pete

I do notice more punch and amybe more low end with this new PS.

You do.
This is no Dynaco.
