Can you recommend a suitable replacement part?
I tried to tune my P6 with a tuning fork. That's right, a TUNING FORK. The result was quite shitty. Ok, I'm going to use a real tuner, I just didn't have anything better at my hands at the moment.
About the calibration procedure... I found some parts of it a little bit confusing. Maybe I just wasn't paying too much attention or I misunderstood something. Anyway, some of the tweaking didn't really do anything... VR1 for example. What's the "circuit board slide swich"? I assume it's the "SW1" on the KLM-366 board, but which position is "away from VR1"? What's the function of it, anyway?
Sorry if I'm stupid or something, I'm just an electronic engineer, forgive me :D
