Hi Ken
I've been troubleshooting my 5 Band pass array on my COA VV4 panel.
On the lowest BPF the influence of the Freq pot only kicks in at the last few mm of pot travel towards CW. I've beeped out the connections for both pots , they are correct. Could this be a blown TL072 causing the problem ? Can't see much else on the board apart from resistors , caps and a couple of diodes.
Regards
