I believe Bigus rewired the handset at the telephone terminal block as I suggested in post #10 (he may have put it back, of course) So I'd disconnect the handset from the telephone terminal block, leave the dial disconnected and chase for 150 ohms round the loop from across terminals 4&5.
If you get a resistance here, then there's your fault. You may need to snip one of the wires to the 0.1uF cap as they're soldered on. It's not unknown for wires to snag and touch at switch contacts or the ASTIC.
