Hi Clint,

?

I don’t know about the electrometer tube but I noticed that Michael says that they work.

?

I have put the kits in a lot of CD V-700s and they are great.? I even put some in the older Eberline instruments.

Lenox,

I have ordered the item from eBay.

I also have a CDV-715 n repair. Do you know if a 5886 electrometer pentode is a direct replacement for the hard to find Victoreen VX86?

Clint

Thank you,
Clint
