Details:

Somewhat dusty from sitting on the shelf unused for so long. Assume that it doesn't function and needs to be gone through by a qualified technician. Vintage rare early 1950s Masco PA vacuum tube amplifier. I hesitate having it done now since think most musicians in search of an like this will have their personal preferences live and recording sound performance.

This has been in storage for many years and the outside looks to be relatively clean very good condition. This is untested so please understand that before buying. I may have a local tech go through it if this doesn't sell, then will relist.
