Unless you were on a cross country trip most amplifiers can still handle a covered heat sink for less then an hour. So while it's possible no, does not make sense. Is this your "600 watt" 4 pill from the other thread?

I was yacking and driving for close to 2 hours. So if it was not heat related then what was it? I mean the heat sink was painful to touch, I could smell the leather/burning smell. you could even see where the heat sink had changed colors around the pills.

I remember when the 1446 transistors were $15 a piece just 4 years ago. The Asian countries are bleeding this country dry.

Yea........2 hours of heavy talking covered would do it covered like that the more I think about it. Is it a Palomar 400 or 450? At H&Y a new 450 with 1446 finals is 239. You will probably need to do all 4 finals and maybe even some other burnt parts. You might have 175-200 in it to get it fixed right.

I would list it on E-bay as for parts or repair, you might get 25-50 bucks. Combine that with the repair money and you can go new.

Palomars are throw away amps...use them till they blow then throw em out and buy another one.

Yup, Palomar is one small step above Boomer Amps and Boomer's are just above junk.
