Teac Tascam Capstan motor PCB 51675661 have 2 of these and

have 2 of these and of course can be used for other projects

The top is in good condition with a few scrapes to the front but nothing too bad

Used I believe on the Teac A3300 and maybe a few other models of this era

We have all of these heads now professionally tested and re-lapped by an external test house

this is the 4 track head

Teac Tascam Capstan motor PCB 51675661 have 2 of these andThis is the standard PCB for controlling the capstan motor of many of the TEAC TASCAM reel to reel recorders going back many years, I have seen some differences in some , maybe some newer components etc etc but they always have the same connector so should be compatible, you see sometimes people selling motors without this board as normally they are sold together or get separated when people parting out a machine. For sure works with EM1446 one way
