Top Gear Flanger Schematic Required

[gaztech]

Hi guys,

A good client of mine recently gave me an old 70's British Top Gear Flanger for attention.

Most of the circuit is pretty standard but the oscillator circuit is weird. Although the oscillator is working, for some reason the clock isn't getting to the 4013 flipflop that drives the BBD. As a result the flipflop isn't being triggered properly. Oddly, the clock seems to go off in all directions on this board so I really need a schematic to get to the bottom of it. I don't have time to reverse engineer it...

Does anyone on here have one? I've looked everywhere on the net and can't seem to find anything for this range of pedals.

I found a link here that recommends the replacing 4011 & 4013 IC along with the electro caps.

Can you post a good clear photo of the component side? Move any wires out of the way.
And the foil side too. The photos above are not quite clear enough.

Useful but I have already replaced these components as they are the most obvious culprits. At the 4001 I have a very healthy clock signal. This then goes to a load of other components - all over the place!

The clock at the 4013 CK pin is VERY low so the flip flop driving the BBD won't clock. Navigating around the board isn't easy so hence the need for a schematic. It's one of those items that doesn't lend itself to spending loads of time on it. If it was mine then ok but I can't warrant spending hours on it randomly swapping components.

I'm hoping that someone may have this drawing... It must be out there somewhere.
