Re: MF-2200 repair

Thanks, I just ordered one. Only $8 with tax and shipping.

Does anyone have a suggestion for a cap to replace the white .5uF 100V? Something similar to what CJ used originally?

Re: MF-2200 repair

Hi all, Sorry I haven't responded sooner. I was waiting for a notification of responses. Let's see, I'm just going to respond to all of the questions but not in sequence. There is a thump and a hum. Both of them have always been there but they've both increased in volume. I do have it connected to a...

MF-2200 repair

Hi, I've owned an MF-2200 for a long time, it was my first CJ. It's always had a pretty loud hum through the speakers. I took it a part to do a cap upgrade and decided I didn't have the money to spend on this unit, and so it sat for a few years. I'm now trying to get back at it. I tried some Mundorf...

MF2200 upgrade questions

Hi, I have a MF2200 that's been sitting for a while. I've always wanted to do a capacitor upgrade to see how it would affect the amp. I thought I would replace the Electrolytic PS caps with some Mundorf Mlytic AG caps of the same value. These are about the same price as some Nichicon's of the same v...

Re: CJ's new Teflon Caps

Hey Roberto,
Thanks for your reply. I keep hoping a lower priced alternative to Vcaps will surface on the market, but so far such is not the case.

CJ's new Teflon Caps

I'm curious as to who's making the new Teflon caps for CJ. Does anybody have any ideas? I doubt they're buying them from V-Cap.
It would be nice to find a lower priced alternative to V-caps.

Any suggestions?

Thanks,
Don

Re: Premier Fourteen Preamp. Wanted

I know this is old, but I have a Premier 14 that I would like to sell. It's been modded by Bill Thallmann at Music Technologies.
I'll PM you.

Thanks,

Re: Preamplifier Premier 16Ls2 schematics wanted

Hey JeffreyBehr, Would the upgrades you specified for the 16LS2 be applicable for a 16LS? What's the difference between the 2 models? Do you have any other info about the upgrades you specified? On a different topic, I have a Premier 14 that Music Technologies modded. They added small value TFT V-Ca...

Premier 11A mods

Hi all, I bought a new to me Premier 11A recently, and I'm not as enamored as I'd hoped I'd be. This came after auditioning a MF-2550 which I loved, but couldn't afford to keep. The bass on the 11a is kinda boomy, and I'm not hearing the liquid mid range I was hoping for. On the 2550, the bass was t...

Re: Any thoughts if this will get me into trouble (KT-150 related)?

Him all, I know this thread is a few months old, and my reply is a bit off topic but here goes. I just purchased a Premier 11, and am looking to do a few upgrades. I purchased a quad of KT-120's to liven the amp up a bit, and while they did tighten up the bass, the highs seems to be kind of dry and ...

Tube rolling and recommendation in a Premier 14

Hi, I've been trying some tube rolling with my Premier 14 preamp, and I'm not hearing a difference. Are there listeners here who have had a similar or different experience? I've tried Sylvania's, Mullard's and Hitachi's. I read somewhere that the rear pair of tubes have more of an impact on the soun...

Re: First bad experience with CJ

I had a similar experience as the OP. Ed was always very helpful, and enjoyed the conversation on the phone. Not so much with Jeff. I bought a demo'd MF-2550 off of Amazon (via Spearit). I knew it would not be mint when I got it, but it was poorly boxed from Amazon (not original) and was falling out...

Re: Power Switch Out On Conrad Johnson MF2200

I realize this is an old thread, but when I wanted to control my MF2200 from I switched outlet, I called CJ and they said it was ok.

Re: Looking for a new tube amp

Hi Peter and all, I'm happy to report that I picked up a Premier 11a this past week, and really enjoying it. I got it for $1750 shipped, and it's got a relatively new set of Svetlana 6550's. I also found a set of TungSol KT120's for $110 shipped and I'm looking forward to some tube rolling. Peter I ...

Hi Peter, Thanks for your response. You definitely got my head spinning with all of the information. I would really like to hear the differences in output tubes, as well as different designs. Heck, I'd like to get my living room remodel finished so I get back to listening to music. It wasn't me who ...

Looking for a new tube amp

I'm new to the forum, and want to ask for a recommendation for a new tube amp. I stumbled across this site when I was searching for a Premier 11a for sale. I'm in the market for a new amp, as I'm still chasing that "sound". It all started out about 10 years ago with a pair of Totem Forest ...
