I bought this deck new in 1978. It has been a total workhorse. I continue to use it today. Sadly parts are getting harder to find.



re: A-2340SX

Ditto on needing the Owner's Manual.


This information will help me revive my reel to reel thanks

re: Manual

You probabaly need the eight pin octal plug for the back socket, it jumps the connections. No function without it or the remote extender control switch box unit.
