What tubes and where to buy them? Conrad Johnson


Hello!

I`m from Brazil but currently I`m doing part of my PhD at University of Florida.

Back in Brazil I have a Conrad Johnson Premier 3 pre amplifier and a MV55 power amplifier.

I need to buy a new set of tubes for both, since it`s very hard to find tubes in Brazil.

The tubes they use are:

Premier 3: 2 12AX7, 5 5751, 2 5965
MV55: 2 12AX7, 2 6SN7, 4 EL34

I would really aprecciate some advice on what tubes I should buy and specially where can I buy trustable audiophile tubes, and not guitar amp tubes. I`m looking for a cost effective option because I won`t be able to spend a huge amount of money with that.

Also, I would like to know what tubes should I start changing if I can`t afford changing it all.

Thank you vety much!

Thank you all for your help. It has been very useful. I`ve already asked for a quote to almost all those folks and web sites you all have recommended me. Drrsutliff and Bifwynne your recommendations were very valuable! Thank you!
Does anybody know if Andy Bowman from Vintage Tube Service is still in business? I`m trying to call him on the phone number that is showed in his web site but it won`t answer.

Thank you!
Pedrod 45: The Tubecenter on ebay. Just had great service from them on 6GK5 tubes for a CJ Premier 14. And yes, Andy is still in business. Spoke to him last week,
