It looks like bias caps were possibly changed when it was converted to EL34 but filter, screens, and mains caps were not. It’s overdue for a recap/overhaul. It does look like it has original iron, which is even more of a good reason to recap it if you don’t want a dead PT or blown cap down the road causing a corrosive mess in the chassis. Ask me how I know.
It looks like preamp sockets were coated with some type of white epoxy but the original sockets are still present, so hopefully the preamp tube sockets won’t need replacement anytime soon otherwise it will be more in labor.
Otherwise it looks stock minus one cathode bypass cap. Price seems a bit high but in this market that seems fair if it’s in working order.
I’d grab it if you can. Good luck man!
