for sale a amp from a reel to reel player. Amp does not have a power or output transformer s which were probably.  connected to the wires that are cut, the square part is a choke I believe.   Amp is  untested as well as  the tubes. Someone rebuilt this amp with real nice parts. This would make a great start for a small tube amp project, not sure of brand ,maybe rca. Amp comes with the tubes in the pictures. Only ships to usa.
