Help with a mystery vintage amp head


An electronics repair guy gave me this amp head with no markings on it. It looks homemade or from a kit. It has 4 nine pin tube sockets and four right pin tube sockets, 2transformers and some old looking armaco caps. Where kits common back in the day? What where they modeled after? I thought the knobs might be a good way to date it. Annoying that I can't post pics of it, any leads would be greatly appreciated. Thanks

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.
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.
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.
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?
