    Control board

    Hi Ed, Playing around with a full comp 400 series II. Amp is working fine. Are there any component replacements on the control board I should do? Or leave well enough alone? Photo attached. Thanks, Fred

    400 Series II (standard) repair

    I have 5 or 6 unconverted amps in the closet so thought I'd play around with one to see if I could get it going non-WOPL mode. First thing I noticed was repair work replaced all the outputs on the left side of the amp and all the emitter resistors as well. With ceramic. Then I noticed that each...

    700 Series II with 700B transformer

    Carver AV-705x

    Not designed by Bob Carver, but interesting. Did a number of upgrades to this. New panel mounted RCA jacks. Original PCB mounted jacks tend to fail when used with high end very tight RCA cables. All 5 on this amp were destroyed. Replaced all 5 relays, one on each amp board. Strange white...

    Fred's "my wife thinks I'm crazy" 700B conversion

    Had so much fun doing 400s I figured a 700B was in order. Chassis is ready. On to the backplanes. Edit 10/12/14: This thread is for the guys (or gals?) that are interested in trying to do a WOPL mod themselves. It's doable assuming you are able to: 1) solder without mucking things up (temp...

    PL400 Backplane Rev B

    Spent most of the long July 4th weekend doing another 400 conversion, this one using Joe's new Rev B backplane with the cool new socket cups. Congratulations to Joe on doing it yet again. Rev B is just outstanding. Fred.
