    replacement power switch for Conrad Johnson PV2?

    I have a Conrad Johnson PV2 whose power switch is stuck in the "on" position. I'd like to replace it rather than continue with it plugged into a power strip to turn it on and off. Conrad Johnson just told me they don't sell parts. They said they'd replace it for the price of the part plus...

    Conrad Johnson PV 12 vs PV1

    I have been considering trying a tube preamp. I currently have a Marantz 3250 pre and 300 DC amp with ADS l1290’s. Two Conrad Johnson preamps are being sold locally close by. Pv12 and a PV1. They are asking roughly 1,500 each. I can probably get them to come off that a little. Any opinions on...

    Weak Output CJ PV 1

    Everything had been fine earlier today. Just turned system back on after a few hours away and I was not getting any music, I thought due to issue with TT. I checked it all, swapped carts and double checked. Still no music. Went to CDP. Nothing, but I thought I maybe heard something very faint so...

    Tube, solid state, or hybrid pre amp recommendations?

    I just got a pair of thiel cs 3.6 and I’m looking to replace the pre amp for the system before I get a new power amp for the thiels (using an adcom 5800). I’m trying out a counterpoint 1000, looking at a cj pv10, arc ls2, rogue magnum 66, Cary audio slp-88. And a few others that didn’t really...

    What to power Renaissance 80's with?!?!

    I have a pair of Renaissance 80's and was uncertain weather to keep them or not. But after listening to them many times the hunt for a better amplifier begins. I'm currently using a Samson s1000 amp and a Yamaha RX-V663 receiver as a preamp to power them. I am pretty satisfied with the the...

    Conrad Johnson MV100 blowing output tubes

    I'm helping a friend fix his Conrad Johnson MV100. He brought it to me last year with blown output tubes. I found the bad ones, replaced every tube that didn't test new, set the bias and off he went. It ran about a year, now he's back with more blown tubes. (left channel only) I thought I would...

    Looking for Conrad-Johnson PV10B schematic

    Hi all, Do any of you fine people happen to have the schematic for the C-J PV10B preamp? I have one on the way to me now via UPS from a nice gentleman in Alabama, and I'm curious to see how exactly it differs in circuit design from my current PV10AL (other than the obvious addition of a phono...
