What is the capstan pulley size in inches for teac 3340? Is the pulley for the 2340 1/2 that size? If yes where can I buy one? I need to half the speed of a 3340 in order to play tapes from a slower unit. That unit is long gone. This unit was FREE. I have no intention of buying a machine just for this purpose. reeltoreelguy@gmail.com.
