Need Help Identifying Unknown Power Amp

[RSMRecording]

Hello,

This is my first post in this particular section on AK, I have been member since 2015.

I have an old power amp kit or homemade unit and I don't have any information regarding its origin. I searched in google for an 1 hour today trying to find a kit manual or vintage AD. I thought it might be Heathkit related, but no results.

The amp is a stereo HiFi power amp with 2 SanKen SI-1050A (50 watts Hybrid Power Modules) and Dektronics 110V, 60 Hz transformer. The amp appears to assembled on a generic metal chassis. See Photos Below for details.

I hope with your help I can figure out what this amp is and does best.

PS: Works great, only a little bit of background hum and super loud.
