This listing is for a Vintage Ramko Research MAS-1 Monitor Amp & Speaker.

Surplus from a government lab. Prior to listing it was powered on using a borrowed fuse holder (not included) and when the volume was turned up we heard a quiet hum. No further testing was performed. Due to the limited testing and because vintage components can fail at any time it is sold as-is, officially "for parts or not working" though it may work fine, may be faulty but repairable or may be shot - we just don't know! Listing is for the unit only with no accessories. In fair cosmetic condition with scuffs, scratches, marks or sticker residue. The fuse holder is missing - it uses a 1/16A SloBlo fuse.

This is the only one on the market - don't let it get away!
