help needed with old detector

[dbanner]

you are right. Those tracks look terrible in post #110, especially the one running along the bottom of board.

Hi again dabanner.

i tried that adjusting capacitor and all i got was a very, very tiny amount of extra sensitivity.

[dbanner]

try changing the 30k for a 10K

I wouldn't trust those old electrolyte capacitors anymore, after 40 or so years & unknown storage conditions. They might have gone funny inside.
Put in new ones if you can. Shouldn't be too much work.

[dbanner]

yes, good to change out old caps.
