These four RF switches are suitable for use in a high power linear vacuum tube amplifier, high power ATU and similar. Remove wires from some of the terminals, give them a good clean, and you’re all set to go.

Switch#1 is two sections, each section one pole eleven way.

Switch#2 is also two sections, each section one pole seventeen way

Switch#3 is one section, each section two pole four way.

Switch#4 is three sections, each section one pole eleven way

Switches will fit in a small Canada Post flat rate box and will cost $16.99 anywhere in Canada (until rates go up – which does happen)
