Description

This kit can be used to restore the vibrato in a vintage Peterson pre amp when the incandescent bulbs have become faulty. As the vibrato bulbs became unavailable we wanted to devise a way to preserve vintage Peterson pre amps that, aside from having a blown bulb, are in perfect working order.  So, we designed a circuit that perfectly mimics the cat's eye vibrato of the vintage design but utilizes readily available and robust modern components.

Replacement Transistor Pinouts May Not Match Original.
