    Back with another electrolytic question.

    I’m replacing C-50, red circle, and C-48, blue circle, and want to ensure that I get the + and – connections correct. I’m ok with + connections but I assume all the negative connections from C-50 go to the green box chassis ground, but where does the – connection from C-48 go? I’m assuming it’s chassis ground as well but I can’t tell where the existing – connection for this electrolytic is. The only connections from C-48 are the wire to 6F6 and the 47,000 ohm resistor from C-50.

    I would appreciate any assistance.

    As I’ve mentioned in previous posts my schematic reading ability is lacking and until I have a chance to go to a vintage radio club or meet with a member to get a hands on lesson you will have to be patient. I can read a text book and unfortunately it just doesn’t sink in.

    Both of these electrolytics have their negative terminals connected to the can, and the can is bolted to the chassis, so that is the negative connection. If you look at the chassis wiring diagram on page 6-4, these two caps are shown as hexagons and both show the neg terminal of the cap going to ground, inside the hexagon.

    Thanks Alistair. That clarifies that issue up for me. Much appreciated!
