[Amps] Question: Where to buy?

[w4foa at comcast.net]

Well, once again, you all have been most helpful and I thank you for that ! 
Looks like Chinese 3-500s are in my future. 
A couple have asked about my problem with the LK-500ZB. After reading several comments, I suspect my problem is associated with heat. The fan on my ZB was quite noisy, I ran it on the low level but I did run an outboard fan, pulling the heat away from the tubes. There was a moderate level POP, but no smoke. Initial analysis is that both tubes are dead, the Zener is also dead. 
I wouldn't be surprised to find another component has fallen victim. 
Thank you again for your excellent responses. I will be back soon, seeking more advice.

Any suggestions as to upgrading any components while the amp is on the operating table?

I can't tell you how impressed I am with the knowledge and willingness to help by members of the Amplifier Reflector. Having said that, I have had some serious problems with my beloved Amp Supply LZ-500ZB. I will need to replace the 3-500Z's finals and zener, etc.....as I repair this amp, I would like to DO IT RIGHT so that I can have another 15 or so years of trouble free operation. 
The question right now is are Eimac 3-500Z tubes available and if so, where may I find them. If not, is there a comparable brand and if so, what brand and where may I find them. 
Thank you for your time and advice. 
There will be more questions to follow, I'm sure.

PS: Is there anyone on here that has had experience with the Amp Supply amplifiers?

Subject: [Amps] Replacing light bulbs in a Command HF2500E 

Can anyone tell me how difficult it might be to replace the light bulbs in my Command HF2500E amplifier? The bulbs that are in there are not nearly bright enough for my taste, I have heard that the meters are held in place with some kind of rubber type glue or silicone. Also does anyone know of a direct replacement L.E.D. for these bulbs? I know that I am asking for a lot but in this crowd I have seen an awful lot more done with less. 

Thank you and 73,
