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!

You could also just order the proper tube sets from cj.

Pedro45...I really thought that the tubes from cj would be less than what NOS tubes will run you. Your preamp, (one of my favorites BTW) uses (9) tubes and the amp uses (8).

Jim McShane is a great recommendation along with Brent Jesse. I have bought tubes from both of them. My favorite tube supplier is Kevin Deal who owns Upscale Audio.

I think you will find that decent NOS tubes are going to cost you a fortune, but you never know.

Good luck on your search. Tube rolling can be fun, but you can also drive yourself crazy. I'm been collecting tubes for over 30 years and have 4 drawers full of tubes that I have acquired. I've always said that I could probably retire on what these tubes are worth now.
