Was cruising my local music equipment sale section when I came across a “free tube amp” and saw the gentleman had posted it 3 minutes prior to me seeing it so I messaged him and offered him $20 to secure it for me and I’d be there in 20 minutes. Show up and he gives me a 70s? Music man 212 sixty five. I don’t really have any experience or knowledge of music man amps or amp repair. I usually just bring it to my trusty amp tech and he gets them all nice and working again. However, I’m stuck between, do I just dump it on my guy and pay the repairs or do I try and do it myself? He said 9 years ago he bought it with a blown transformer and he repaired it himself but said he wasn’t great with amp work. Then one day 5 years later he turned the amp on and he said there was no sound and he could smell a burning scent. He flipped it off and replaced the tubes the next day and still no sound so he stashed it away in his closet for 4 years and decided to give it away today. I picked it up, plugged it in and bam, clear loud and a normal sounding guitar amp. I quickly shut it off however incase it was going to to start having its precious issues. So, it works? Now, what’s my next best step to seeing if it actually needs some repairing or if I can play as is until it explodes. I’m not really looking to spend much money on repairs at the moment. Is it even an amp worth fixing? Any info is greatly appreciated. Thanks so much!
