Solid State Transformer Substitute

Design by: 24497

This board is for a solid state transformer substitute to be used in 1920's vintage radios that often have faulty interstage audio transformers. The purpose of these boards is to allow the original audio transformers to remain in place to keep the original radio appearance. The solid state substitutes may be hidden in or around the original transformers and provide the proper audio gain for the radio to function.
