Help My

I just bought a used Conrad Johnson PF-R pre-amp here on Audiogon and I'm having some problems. My amp (Citation7.1) keeps overloading (the red indicator light goes on and off and the unit shuts itself off altogether then comes back on It does this even when there is no music playing through it. If I turn the amp on (the CJ is always on) and just let it sit there, after about five or ten minutes the problem begins. I do not have this amp problem with any other pre-amp hooked up to it, it only occurs when the Conrad Johnson is connected to it. It seems really strange that this would happen even when there is no music playing. Is there some kind of short circuit going on in the CJ? I wanted some expert advice before I contact the seller about this problem. I should mention that the pre-amp itself never seems to show any signs of distress and when I'm playing music it sounds fantastic.

Thanks,

Steve

Well I don't see any swithes or adjustments of any kind, but other than that I don't know what a DC offset is.

I don't think it's the interconnects as I use the same ones with my other pre-amps and there is no problem. When you talk about DC on the preamp output, is this a normal condition or a sign that something is wrong with the unit. If the unit is defective I want to notify the seller. I think he offered a 90 day warranty on it. The other problem is that love the sound of it and would really like to keep it. If the seller will make good for repairs that would be great. Does anybody know of a good place to send it for repairs? I don't know of anyone.

Thanks,

I emailed the seller but the email has been delayed for some reason. I notice that the seller has some other CJ equipment for sale here and on eBay and offers the same 90 day warranty on these other units. After taking the CJ out of my system and putting the preamp section of my Denon receiver back into service, I immediatly packed up the CJ to send to Conrad Johnson for repairs. I didn't seem to notice THAT great of a difference when I first tried out the CJ but boy oh boy, I shure missed it when I had to remove it.

I called Conrad Johnson and the customer service rep. was extremely heplful even though I told him that I had just bought this unit used. He spent a great deal of time with me on the phone, asking lots of questions and in the end found that the intermittent nature of the problem was strange and needed to be looked at by a technician. So the preamp is on it's way to Conrad Johnson.

I probably should have waited to hear from the seller but the CJ rep. thought that it probably wouldn't cost much to fix and I like the sound of this preamp so much I just have to keep it. Who knows, maybe the seller will cover the repair costs.

For anyone interested I'll post what the techs at CJ find.
