CONRAD JOHNSON MV50 Owners, anyone outthere?

Alan, does your '50 use the great-sounding cjd 'styrene caps? 'Propylenes as main-PS caps and not 'lytics? Do you have a schematic diagram?
.

Thanks for the replies
Makee, Yes,I think iMV45 counts. How is the sound? What is your setup?
And "Alan, does your '50 use the great-sounding cjd 'styrene caps? 'Propylenes as main-PS caps and not 'lytics? Do you have a schematic diagram?"
I have the original manual, and I can tell you the MV50 hasnt had any modifications., The caps you are talking about were the CJs factory originals or they are an upgrade. As soon as I arrive home, I will check, I think there is a diagram in the manual.Jeffreybehr, Could you shed some light on that? , Do you have a MV50?

I have checked in Internet and it says this "The MV50 was, in effect, a more refined version of the earlier MV45. The input voltage amplifier included a cathode follower to provide low impedance drive to the inverter stage, to which it was direct coupled, eliminating one capacitor from the signal path. The remaining coupling capacitors were "cjd" polystyrene. Separate discrete dc voltage regulators supplied dc voltage to the input amplifier and the phase inverter."
So, I suposse My MV50 has that caps.
But, Whats the issue with that capacitors?
Please give us some light

I don't own one but have always liked it. I heard it many times with ML CLSs. It could not control the bass but still had magic.

Hi there,
I used to have a CJ MV45. I figured that a tube amp with my vintage electrostatic loudspeakers was the way to go. Ultimately I had a bad experience with my CJ equipment (both pre amp and power amp). They were very unreliable and poor quality. To make matters worse, I received rather poor support from CJ. The transformers in the MV45 buzzed significantly, and the capacitors failed (CJ initally claimed they were OK). I had to send the transformers to the manufacturer to have them reimpregnated (again no help from CJ). When I took it apart, I noted that the single-sided, hand laid PCB had an intential gouge throug a trace which I concluded was there to break a ground loop in the layout. I was happy to sell these units (nearly gave away the MV45 due to the cap replacement cost).
Ultimately I concluded that tube amps are unreliable (esp CJ) and have significantly more distortion than properly designed transistor amps.
