Excellent parts!

I bought these parts for a souped up F5 running, what I intended to be, 32V rails, which actually proved to measure 34.5V rails, and was concerned that the J74 part wouldn't tolerate that kind of overvoltage well. As it turns out, the pair handles it like champs with a little bit of heat sink between them. They're excellent parts working very well beyond their technical specs and they sound excellent. VERY pleased with them.
