RCA 5R4GY Brown Base 1950's
Beautiful rectifier tubes from 1950's. These have smooth black plates, square gettersand support rods. Preferable in place of 5U4 over 5U4GB with its more airy and clearer sound. Some tubes are labeled and boxed for Lewis and Kaufman/Gatos. All NOS and MINT!

Quantity in stock : 4 pcs
Price : US$ 49.00/each
