Astatic 575-M6 Teardrop.

Post by Tim » 20 Nov 2017, 10:05

Picked up a tatty teardrop at a local rally yesterday and it's in need of a bit of TLC. The battery connector was rather corroded and the earth wire had parted company with it, new connector fitted. There is another wire that's floating on one end, this is one of the element wires which has parted company from the circuit board, it's pale green, the other, which is still attached is a dark blue wire. There is no evidence where this pale green wire goes onto the board, I've looked at another to compare but this one has a creamy coloured board whereas my other has a green board which is totally different. Can anyone tell me or show me where this wire solders on the board to please? I can put up a picture or two if required.

Thank you Claude for the schematic but I'm afraid it means very little to me.
Here is a picture of the board, it's that I'm looking at to figure out where the green wire solders on to.

From your pic it looks like the mic element wires is. red wire circuit gnd /Green wire audio input to amp transistor. Get the schematic on cb tricks.com or astatic.com. gd luck .cheers n 73's

From what i can see the green wire leaves the mic element and attaches to the top of the potentiometer

Please excuse my ignorance but where is the potentiometer and at what point on the board should the green wire be soldered? An arrow pointing to the point of attachment would be the most helpful.

If im not wrong, any of the 2 points marked with yellow arrows, just DO NOT remove that red wire link when soldering it back in place
