Vintage Synth Repair

Hi,

I recently bought some synthesizers for a very low price, most of 
them aren't working. But i would like to fix them, one of them is the 
ARP Explorer I and the Omni MKII.

If anyone of you guys have a service manual or schematics please let 
me know, also i have some spare parts for other synths :

- Polysix, Monopoly potenciometers and switches
- Roland Juno 106 Power supply, color buttons.
- Crumat Bit 99 various parts.
- Rolsnd SH-1000 various parts.

Thanks,
