[AMPS] Triton - Glass tubes ??

[Paul Ferguson]

> >>> Yes, Richardson is the distributor for Triton, Amperex, and Eimac.

I purchased two Amperex 3500-Zs from QRO Technologies to replace some 
Chinese 3500Zs in my HF-2000 amp. One of the Chinese tubes went bad 
after about 4 years.

Just under a year, one of the Amperex tubes went bad. It would draw grid 
current intermittently with no drive. I swapped tubes in the sockets and could 
see it was isolated to one of the tubes. I put the Chinese spare in and the 
amp runs fine.

QRO purchased the Amperex tubes from Richardson. I delivered  the 
defective tube to Richardson on Jan 17. It has now been almost 15 weeks 
and they have not declared the tube defective and replaced it. They say they 
are waiting for their vendor to test the tube. I have contacted Richardson 
about 10 times asking what is the status. It is always the same -- we sent a 
message to Amperex and have no word.

Richardson is willing to send a new tube only if they can bill someone if tube 
is declared good by Amperex.

I have no problem with someone testing the tube. I am certain it was bad. So 
far Richardson reps have been pleasant, but brought nothing to a conclusion. 
I am open to suggestions about how to get them to send me a replacement.
