Help me identify an amp

My father, who recently passed away, was an avid audiophile and very proud of his stereo. I’ve been taking inventory of his gear, and while most things are easy to identify, I can’t find any distinguishing marks on this power amp. Can anyone help me identify it? The power tubes are 8417s. Thank you!

+1 on the variac and nice and slow you don't want to fry the amp especially transformers which are the best part.

connect some speakers, any load, when you power up tube amps

+1 variac - to bring up power slowly/safely to see if working, especially for tube type amps.

I bet it will sound great.  People are still making mods for the ST 70.

Tubes for Hifi makes the kit similar to these amps called the VTA ST-70. Also have a ST-120 version. All their stuff are modifications to the original Dynaco gear. I’m sure they could help you source any parts you need to replace and also help diagnose any issues you are having.
