Troubleshooting a 50 Cal. +

Ldthomas said:

Hi folks. I'm new to Mesa Boogie having picked up a 50 cal. + recently. I've had tube amps through the years, but have NO electronics background. I'm starting to think the reason it was so affordable is, as it gets good and warm (after about 15 minutes), it starts to fade in and out. Yeah, caveat emptor. But I wWILL get it running right!

Any suggestions what the problem could be? I'm taking it to a qualified service person in the next week, but any clues to ease my anxiety?

Thanks
Larry
