keep it running anymore! What is a vintage radio aficionado to do to keep his or her vintage tube equipment running?
The answer: Our PeKo RVB-1 solid-state radio vibrator board. This board was specially designed by us to replace a wide variety of radio vibrators, WITHOUT the need of any modifications to your vintage equipment. The RVB-1 solid-state vibrator board is designed to be a direct drop-in replacement to many different mechanical vibrators."
