A single 3CX800A7 or the 3CPX version is an easier conversion since none of the extreme metal hacking for Russian tubes is needed; the socket and pin outs are identical. Plus the tube is much cleaner for IMD and full to 80% output (at 46 mHz) medical pulls are still fairly easy to find.

Go with the GI-7bT variant if you can obtain them instead of the regular GI-7b. You also might consider a single GS-31b. That tube has a plate dissipation of 1000-watts instead of 700-watts which a pair of GI-7b or GI-7bT tubes have. Glen, K9STH

Dear OM`s:

I have an old Dentron, and I need to buy two 8875. Can anybody help me with
this? If not possible, a pair of GI7B is a good choice?

Thank you in advance.
