Output on 75-40 and 20 seems ok, but 15M is low, and 10M is near nothing. The driver power doesn't even seem to get through. Just looking for someone to agree that I need two new 3-500Z's before I put out the cash as I am on a fixed income. Also, I'll go to RF Part to replace if need be, which 500z's aould be my best bet price vs brand?
Tnx es 73's

If you're buying tubes, RFP "brand" is very good, I've had nothing but good luck with them.

However, did you check:

-What is the SWR looking into the amplifier on 15 and 10 meters?  If it's high, that has nothing to do with the tubes.

-How much grid current are you achieving on 15 and 10 meters?  If it's "low," see the question above.
