I am attempting to bring back to a life an R4B with a botched electrolytic cap rebuild. Whoever tried this unsoldered all the connections and with my limited ability I am struggling to put it all back correctly. The cap is a 4 section with 3 100 uf and one 20 uf cap. I need to know which wires go where. There are caps marked with one square, one half circle, and one triangle with the other terminal being unmarked. The wires are white/purple, white, blue/white (2), and red/white (several). In addition there is one 1000 ohm resistor. I think I have everything nailed down except the one white wire which goes from one of the 100 uf caps to somewhere – that somewhere is unknown as the wire is completely unattached.
White/purple to 22 uf Blue/white to 100 uf Red/white to 100 uf White to 100 uf but I don’t know where the other end terminates in the rig. Resistor across white/purple and white/red
I have been staring at the schematic and can’t figure it out.
Help!! |
