Unfortunately, Mike, I believe it was the D5 that I squirted into the pot. I had both cans sitting side by side, and was going to use that in the sockets and the F5 in the pot, but grabbed the wrong one by mistake. Easy enough to do but it could have been the cause of the volume fluctuations I've been experiencing.

I haven't had a chance to see if the flushing with the WD-40 fast drying contact cleaner did any good but will get down to the workshop later today.
