Vintage Synth Repair

hey all

While the jury's out on my Farfisa question, I have a couple of 
nagging problems with my Multimoog that I'll put forth a request 
for assistance about:

1) The Attack control on the VCF often (not always, but much 
more than it should) does not want to go faster than about 0.5 to 
1 second attack time. In other words, you turn down the attack 
pot full counterclockwise, and the VCF still wants to go 
"wwwaaaaaa" instead of "wa" or even "a". A while back I replaced 
the capacitor associated with the VCF envelope generator but 
seeing as how it still does it off and on (currently on) that's 
obviously not the answer.

2) The oscillator sync function doesn't seem to be working at all. 
At the same time I was working on the capacitor problem above, 
I remember accidentally dropping a screwdriver on the PCB 
which blew out one of the CA3080 chips and put the synth out of 
commission until I could replace it. Is it possible that something 
got zapped on the sync board as well?

Any answers or suggestions for these two thingies would be 
most appreciated.

thx
