Tube breadboard sockets

[nosaj]

For bread boarding a circuit I'd always looked for the relay octal sockets. But take a look at the ones i found They are made by Pomoma XS series in 7,8, 9 pin sockets.

These are great for experimenting.

Breadboarding sockets and components were a really big thing that largely disappeared after the 1930s. Whole radio sets, sometimes quite complex, were built using them. They mainly had screw terminals and were made so that the home constructor could build an amp without soldering, using square-section, solid-core wire. Components were expensive back then, so they made good sense when you wanted to rebuild a radio or amplifier or use them for something else. Even resistors and capacitors had screw terminals. I have some odd-looking rectangular pieces of insulating material with a terminal at each end. It took me quite a while to discover these are grid-leak resistors - you drew a line on them in pencil for the resistance.

Those Pomona sockets look very similar to my vintage sockets, other than they have solder terminals. Plus, of course, B9A was many years later than the era I mention.

I don't know why I never though of making up some boards with a PCB mount socket and couple of terminal blocks similar to mozz's picture.

I have a similar type thing for those metal can op-amps, if anyone is interested.

I would just add a word of caution with the relay sockets. You may want to double check the manufactures specifications. many of the ones I've come across have max voltage ratings around 300V (or thereabout). This is often okay in preamp stages, but this may be problematic in when used in output stages.
