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!

Pehare,

Thank you for your response! I`ve sent an email to Jim McShane asking for a quote for the tubes I need. Good to know you`re in GNVL. Right now I`m in Ona, at the Range Cattle Experiment Station of UF doing my research.

Mofimadness,

Thank you for your response. This was my first try, but the quote they sent me was veeery expensive and only included new reissues. I think I can get better quality tubes and better price if I buy NOS tibes in the right place.

Still waiting for more suggestions, including tube brands and what tubes should I roll first.

Thank you all,

Pedro
Thank you Lowrider57.

Does anybody know any trustable ebay seller that sells qood quality tubes?
Mofimadness, here is the quote that Conrad Johnson has sent me for the tube sets I need: "RTPR3 is $475 plus $19.95 for shipping and RT55 is $340 plus 19.95 for shipping". These are the tubes included: 12AX7 Mullard, 5751 Sovtek, 5965 GE, 6SN7 Sovtek, EL34 Mullard (I believe all brand new reissue tubes).

I`ve already received a quote from Brent Jessee (BTW, thank you Lowrider57 for this recommendation) and that`s what I got:

12AX7 Sylvania or GE 1960s, $30.00 USD each
5751 GE 2 mica military stock $30.00 each
5965 RCA $14.00 each

6SN7GTB General Electric 1960s $50.00 per matched pair
EL34 Groove Tubes Mullard reissue, $60.00 per matched pair

The total would be U$408,00 for all tubes and I believe that the only brand new reissue tubes are the EL34 Mullard`s.

Lowrider, yes, it`s a lot of tubes!!!! I just want to take the chance that I`m here in the US and take some tubes to Brazil, since once I get back there it`s hard to find this tubes and they are even more expensive.

I aprecciate your help guys!
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!
