This is an Altec A323-B tube amp from the late 1940s or early 1950s. I believe it works; it was plugged in just long enough to see the tubes start glowing, then unplugged. 

It was recently recapped. The glass tubes are modern (one Sylvania,  two Mesas), the others are original. The power cord has been replaced and has bare wire ends, no plug. 

Since it is vintage this item is sold as-is with no warranty expressed or implied. Sale is final, no refunds or returns. I will pack with great care and ship within 1-3 days of payment. Local pickup is also an option (cash only).
