Vintage Synth Repair

Hi, first post on this group.
I realise this is a vintage synth repair group but.. 
Ive got a Waldorf Pulse that i brought s/h as faulty. I replaced the 
opto isolator on the midi in circuitry which restored operation.
Theres one remaining problem i noticed with the panning if i recall 
correctly.. (it was some time ago, actually it might of been something 
to do with the mod matrix with the lfo's leaking now i think about it) 
Has anyone got the schematics for this synth that they could share?
Anyone with experiance repairing pulses here?
Its really hard to get servce data on waldorf anyway and as their in 
insolvency, the company that could help me cant release service data 
until the've sorted themselves out. Mean while its just sitting here 
gathering dust which is not a good thing.
Cheers
Gonz
