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!

Howdy Dave,
Just as an FYI, Henry Radio (yes, they still sell stuff...) has new "Greenstone" 3-500C tubes for sale. They are Chinese (of course), but seem okay, work well, and are "guaranteed"...
I purchased a couple of these a long while back, and they are still running strong. I've run the pair in both my Drake L-4B (that's what they're in now), as well as my Henry 3-KA. They work great, and the price was (I thought) quite reasonable.
Anyway, just another option to consider.
