Hi folks, Long time no hear, but holidays and hospital visits and other things seem to get in the way! I have one of these devices: Smiths Sectric Tuning Fork which has been given to me - it refuses to work buzz, but the two coils are OK, as is the transistor. However, it isn't the same as the circuit diagram that I've seen, so possibly the small electrolytic has given up, as it's a few decades old now. One of the leads connected to the battery has come off, so has anyone one of these clocks and hopefully can show me a picture of the component side? Thanks in advance, Mike.
