I am doing my annual shack clean-out, and here is a new-old-stock/new-in-box, never used UTC VM-3 Modulation Transformer that I am offering for sale.

This also includes the original data sheet and connection diagrams for matching various modulator tubes to various class C load impedances. It is designed to modulate a class C final amplifier stage having a DC plate input of up to 250 watts.

The price is $100.00, plus the cost of shipping to your QTH.

Thanks & 73,

Bruce, W2XR
