[Amps] Eimac 3-1000z Tubes

[K8MLM@aol.com (K8MLM@aol.com)]

I have a home brew 4-1000.  About 10 years ago when I started testing, I 
plugged in a $1.00 hamfest tube I bought to use for a lamp base.  The filament 
lit when voltage was applied, so I applied HV then drive and got RF out... 
nearly 75% of a good tube I finially replaced it with.  I don't know if it was 
a 4-1000 or 3-1000, but it worked.

It's hard to kill one.
