Good testing 8417's are still available for $400-$500/quad, though I would advise picking up spares/matched quads in a timely manner as they are considerably more rare than good vintage EL34's (which also run around $400-$500+/quad).

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!
