NOTE: The keyer output transistor circuit is designed to switch key input

of 13.8 Volts positive or less.

Do not attempt to use any CW Touch Keyer products with a vacuum tube transmitter

(either grid blocked or cathode keyed) without an appropriate output circuit.

Consider purchasing the “keyall” kit from Jackson Harbor Press for tube type keying.
