The warble on my Corsair II was only on certain bands. If I remember 
right, the offending pot on my Corsair II was the pot which supplied a 
preset voltage to the varicap which in turn provided an extra 
capacitance for the frequency offset on the PTO.

The offset is only on some of the bands - can't remember which ones - 
and it was this feature which enabled one of the contributors to this 
forum to spot the source of the problem. At the time I solved it with a 
squirt of switch cleaner but the problem returned so I plucked up 
courage and replaced the pot.

I hope there are other contributors who have better memories than I do 
and can supply more detailed information!
