Help with a mystery vintage amp head

You've been a great help. I'll take it to a tech and see if I can get er going. Also try diyaudio

No. The jacks and the pots are used to set the bias on the power tubes. It requires that the 1/4" plug be connected to a meter; without seeing the circuit closer I can't say if it would be set to DC volts are DC amps, but in the end you set the meter to the right reading using the pots. Both tubes would be set to the same value. Depending on the power tube the correct value shouldn't be hard to sort out.
BTW this amp is really off topic on this particular forum. I suspect you might find better luck- maybe someone might have even seen it before over on DIYaudio.com. They have a section devoted entirely to musical instruments.

I didn't see any markings on the transformers. What are the pots on the inside for? And the 1/4" jacks? Is that an effects loop?

It'll probably be great for blues.
But if the restoration goes well then it might sound a lot like a Fender with better low end. This is just based on the size of the output transformer.

Thanks atma. I forgot to mention the tremolo knob. No reverb. I will try and get all capacitors replaced if I go for it. I have a 2x12 jensen cab from possibly 60s era to run it through. I guess I'm wondering if it's worth it to restore. What kind of sound is this thing going to have.

That's an instrument amplifier.

I would not try to run it until the filter capacitors have been replaced. This amp was probably made in the mid 1950s.

Ah iv uploaded some pics to my system

They sure don't make it easy. Don't see anything on my profile page, faq says very little.

You can post pics on your system page
