I would also recommend Brent Jesse very highly.
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!

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! |
Go talk to Paul at Sound Ideas on NW 13th St. there in Gainesville. He has an a nice selection of tubes and you can discuss your ideas, goals, and budget. Another possibility is Andy Bowman at Vintage Tube Service. You can reference his website for some information, but you really just need to speak to him on the phone. He has great insight to most equipment and what tubes work well. His "perfect pick" tubes can save you some money on very well tested tubes. |
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. http://www.upscaleaudio.com/VacuumTubes/ 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. |
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 |
You could also just order the proper tube sets from cj. http://www.conradjohnson.com/It_just_sounds_right/tech-support.html Tube set for Premier Three: RTPR3 Tube set for the MV55: RT55 |
