[Heathkit] SB-220 TR Relay

[km1h]

Grab a Mouser catalog, there are  a few 110VDC 3PDT in there that will fit. 
Mouser 528-788XC4-110D is the one I use; remove the 528 and the rest is the 
Magnecraft part #. Leave it in the enclosure and mount with double side 
tape; nice and quiet!

I often replace with a 12VDC version. IMO its a lot easier to build a small 
12V PS under the deck then mess around with a Harbach or similar soft key 
that often blow during a big tube arc.

If your rig uses relay keying that can handle the DC then stick with a 110V 
relay
