tubes age 79

I picked up three of these old 6C4's last year. These are in my receiver now.

They are the best ones I have found in several years. Just less noise than

newer ones. Clearly the age of a good tube has no bearing on its performance.

If the vacuum has held for this time, its likely a good tube in a lot of other

aspects.

Both V508 (next to the ballast tube) and the PTO (V701) tube should be 12 v

tubes. The filament supply voltage is 25 volts. V508 and V701 can be lowly

12BA6's. Has been running here this way since I put tubes in the R390 when it

was obtained. Pins 2 and 7 of the ballast tube socket are jumpered. Thanks to

Gerald, K6QY for help setting up this one.

The attached is answer from Radio Electric Supply to my request for 26Z5

availability. You are right. There is most likely little if any stock for the 26Z5

anywhere. The only options is solid state diodes or a sub for the 26z5. Al

I am the tube bank custodian for NM Army MARS.

We have dozens of 26Z5s in the bank.

I cannot sell them, or give them away.

BUT if you are a member of ARMY MARS, perhaps you can get your SMD to

contact our SMD and do a transfer. It is a slim chance, but it is something ....
