I have myself just aquired an VIBROGRAF M80 (without the sensor pickup transducer) The mainboard tantalum caps and logic ic's are all OK ,the unit power's up OK,
The front led display shows (-1 00) .
I need to aquire an user manual and an schematic of the pickup sensor, or pictures of the internals of the pickup , and din plug wiring etc ,etc.
Your help would be much appreiciated,
If you need the I/C s layout of the mainboard, I could send you pictures of the internals of my unit and I/Cs placement drawings via email .
Hope to hear from you, Kind Regards ( Graham Ashton) UK.
