Reel-to-Reel Player--Best Playback Deck 4-trk Stereo-Dependable, Easy Repair, Sounds Great

I sold TEAC many many moons ago and I believe the A2300S was their least expensive reel to reel deck.   I had the next model up which was the A3300S.  The Revox A77 was the best I heard at the time.  My brother had a Pioneer rack mount reel to reel which sounded pretty amazing.  I would make sure any deck I bought would be able to get serviced and parts are still available.  There is a company (can’t remember their name) that totally repairs and modify’s the different decks.  I would talk with them first and see what they say.
