an 8 pin and a 9 pin on one pcb?

I have a pair of 9 pin HP PCB's with old crumbling foam on the back.
I'm sure they were made to isolate scope input tubes (6DJ8) from
microphonics. HP sockets also had heavy duty metal shields/covers.
The original tubes I found inside were branded HP by Amperex.

A small PCB like this might again serve similar function? I am not
too sure what type of foam is supposed to survive the heat though.
Obviously the original material must have gave up after 50+ years...
And that was only in the deadly heat of a garage attic in Texas.

Some board shown at the bottom, can be fitted with standard chassis mountable sockets and a long lasting breadboard is ready.

I'm totally up for 8 and 9 pin versions. Terminal blocks are awesome.

you can "just" make it out....

on my amp I put together a combo 8 and 9 pin board together with turret strips on either side (one red, one black..

Fast and fun for breadboarding

To revive this, are people still interested in this project? I got the OK from DIYAudio to do a group buy.

I received emailed interest from a few people (I'll email those people back to see if they are still interested.)

If we can reach a reasonable number, then I am happy to put together a group buy for both 7 and 9 pin experimenter PCBs. Email sockets@ecp.cc with interest. If a few people show interest, then I'll put together the details. I'd expect ordering for a week and a half or so and boards pretty quickly after that. Depending upon the number of boards, and the breakdown of types, I'd guess between $2.50 and $3.50 per board.

I would mount the sockets in the ends of PVC pipe end caps, with bus wiire radiating out of the caps through holes or slits in the sides of the end caps. Plenty of room to tack on components, wires, etc. for "hairball" breadboarding.

Hi Doug,
I stumbled upon this thread a couple of moments ago and I am definitely interested in getting some. Are you planning on doing octals as well? (I do have octal relay sockets and can use them instead.) I'm interested in both the 7 and 9 pin sockets and would probably take 4 x 7 pins and maybe 6 of the 9 pin sockets..

Unless there is an overwhelming demand, probably not. I think the cost of a board plus a socket plus some terminal blocks, plus some standoffs would push the price higher than the available relays.
