    Wanted: Desperately seeking old caps

    Thanks, kellys_eye. I believe I've seen that combination of values.

    Wanted: Desperately seeking old caps

    Thanks, *Steve*. Those are the kinds of details I'm fuzzy on.

    Wanted: Desperately seeking old caps

    Appearance is irrelevant; I just threw in the dimensions for cross-reference. The only crucial items are the values, although it would be nice if the terminal spacing matched the PCB. I have in fact been through the Digi-keys charts about 3 times, and the 50 vdc/8700 mfd combination seems to be...

    Wanted: Desperately seeking old caps

    I badly need at least two older capacitors: 50 VDC, 8700 μf; can-type with three leads, one nonconnected, placed radially; distance between + and - leads is about 14.5mm. The radius is 30mm and the height above the PCB about 64mm. ELNA was the original manufacturer, I've been checking through...

    Should I check everything?

    Thank you. I think I can cut out the DC.

    Should I check everything?

    I need to replace two visibly damaged capacitors (50 vdc, 8700 μf) in an audio receiver. I don't see any other physical damage, and I've checked continuity, but should I check all components with my multimeter to be sure another problem isn't lurking? Thanks

    JVC RX-450 silent

    Thanks for the detailed and practical advice. I've had to accept the fact that I can't do much until I can get out of this leg cast and back to my workshop. But I do now have a schematic, and I can start tracing out the paths you mention. I have checked the output transistors (powered down) and...

    JVC RX-450 silent

    The mystery of my silent JVC RX-450 continues. The sound I heard from it was almost certainly created by an arc, but I can find no apparent damage--not even a scorch mark. If it was a power surge it didn't enter via the power cable. Nothing else plugged into that circuit was affected (well, my...

    JVC RX-450 silent

    Thanks very much. Right now I'm recovering from ankle surgery and in a cast, and can't get to my workshop. I'm getting a temporary workspace set up and will get back to you as soon as I'm able to check this out.

    JVC RX-450 silent

    OK--there's a place to start. Thanks.

    JVC RX-450 silent

    Hello. I have a JVC RX-450 receiver that I got used but in generally good condition. Recently during a thunderstorm it emitted a loud snap (from the circuitry, not the speakers) and went silent. Nothing else in the house was affected, including my computer, which is plugged into the same...
