I have a Rockford Fosgate RF 200 Pre-amp(It's a Hafler with RF name on it, can't remember the Hafler model but something with a 200 in it).

Anyhow, It's always needed a little warm up time. Sounds great after a bit.

Butttttttttttttt, now it's not wanting to warm up. All I get is crackling to the tune of the music.

Any Ideas what component/s is going bad? I haven't opened it up and looked at caps yet.

I have another vintage pre-amp to use for now, so I guess I'll switch it out and take a look. Hopefully it's repairable, I like it.
