Dual 833A Plate Modulator

\

Introduction

My goal is to build a high-side plate modulator capable of providing ample power to my dual 833A VTTC which will

provide both loud and high quality audio modulation.

RCA Modulation Transformer - Note the adjustable spark gaps.

My good friend Lou Bazin gave me an old RCA modulation transformer which will be the main component of this design.

The transformer was custom designed for two 810 tubes, but will work just as good with dual 833A tubes.
