I heard ye ;)
So after an afternoon of scoping (and taking action) I still have a "corrupted" (slightly distorted on the positice top of my input sine) output signal from the DA section of the MC4102 chip in an Ibanez DDL20 delay. You have a schematic for that!?? Man! That would owe me a cigar to you!

I kept thinking about the emmiter resistor for Q3,4.
I would like to see the original Ibanez value- curious!

See my pm at DIYstompboxes from yesterday?
The you'd know that wanadoo considers my info@ a spam IP and I asked you to provide a different mailadress so you'd have that stuff by now.

hello,
my PT9 was modified by Robert Keeley. Someone he know the changes ?
The obtained lissasjou currently does not correspond to the service manual lissajou Ibanez.

There are three more resistance
and a capacitor more
and perhaps other changes ?
