1962 MCMARTIN TRANSISTER AMPLIFIER LT80A. Don't know if this will work or not. Has a blown fuse, but I have no microphone, or anything to test it with. No nothing about these type units. As I don't know, selling as is, for parts. Please look at pictures and mouse enlarge them to see condition. Any questions please ask me and I will answer as soon as possible. Please look at my other auctions for a wide variety of interesting and unusual items. Shipping USPS Priority Mail. Thanks for looking, David.
