Cathode Current Source

[WntrMute2]

Any source for CCS boards/kits? I've used K&K ones in the past but I'm having a hard time reaching him and he is not responsive on his forum board.
I'm planning on using them on 5687 tubes.
Not skilled enough to create my own.
TIA

Almost 60 views and no one has suggestions. Was it something I said or didn't say?

Try reaching out to Kevin again via phone if required.

this forum has been low activity as of late.

I'm going to move this request over to the Tube forum and see if I can get a few additional recommendations. Thanks all.
