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!

Sorry for your loss.  But at least you have his gear as a memento.  I don't think my pops has anything to leave behind.  He was a car guy but got rid of everything some time ago.  Best of luck!

Oy showing my age.  Looks like an old Dynaco ST70.  Four tube

input circuit is a little different though.
