[BC] 5CX1500 Tubes - Recollection

[Schardin, Hal (DEED)]

I recall the tuning difference between the A and B version tubes in an FM transmitter I used to maintain. I also recall the mention of ceramic seal issue.
Here's an interesting response from an Eimac  engineer on the differences of the A version vs the B version:

The Elcom Bauer one holer would go 14 months on an A or a B ... never saw a difference.
