Default Re: Cyrus 1 Amp Dead....Help!!?

Thanks for your reply AJS....this is exactly what I need!

I downloaded a manual from the HiFi Engine site....
The 4 'hefty' transistors, according to component list on page 38, are:Style TO220, PT7, NPN Power transistors.

No obvious evidence of overheating..

The PT7 seems to be discontinued.....do I go to Mission for 'em........?

Will test when I get them off the board
Thanks again
Kev
