I ordered a pair from Penta Labs a year or so ago, very reasonable price with shipping to VK and amazingly well packed, so far so good in my TL922.

FWIW, contact Tom, W8JI at CTR Engineering.?? From what I understand he has tubes F/S that are tested by him to make sure they are working.

Hello Group, I could use your help!

Looking to pick up a 3-500ZG replacement for my AL-80B.?? My choices are:

RF Parts Company: 3-500ZG (6-month warranty). 250$ (China)

DX Engineering: Penta Labs RF Vacuum Tube 3-500ZG (no warranty listed). 300$ (assume China?)

DX Engineering:? Ameritron 3-500Z Replacement Power Tube (All products manufactured by Ameritron have a one-year limited warranty) 360$ (assume China?).

Both vendors have always been reliable for me so my question:

Is the Ameritron tube worth the additional $$ or is it branding?

Is the Penta Tube? worth the additional $$

What would be the best replacement?

(sorry for writing a novel)

Thanks in advance!
