I would second this suggestion - it is, after all, a "classic" manner in which to do so. But there used to be nine and ten pin "octal like" plugs and sockets and these were often used to prevent someone from inserting a tube into a power connector. Use pins 2&7 or 7&8 - the most common octal heater pins for your heater supply. That way anyone who plugs in a tube accidentally won't short a higher voltage with the tube heater. I'd probably use pin 3 for the B+ as this is the most common power output plate pin and pin 8 for the ground - you'd fry a 6L6, for example, with no bias but the fireworks might be quickly noticed. And of course I assume you're going to fuse each circuit at the socket no matter which type you use. While you can buy male octal bases I just use the ones from dead or "worthless" tubes (damper diodes, TV HV rectifiers) - metal tubes have a nice flat wafer which can be built up with epoxy after the leads are soldered on.Rob
