The first post is dated Aug. 19th so it's been about 3 weeks so far.
I popped out the K6 network to do a little testing. It's tough to do because of the internal parallel and series combinations, but I here's what I found.
There's a 47K and 4.7K in series between pins one and 2 for a total of 51.7K. I measured 70.7K.
Between pins 2 and 7 I should have 3300pF but measured around 4300pF.
Seems to me those are pretty far off and I should replace this network. I'll pop out K2 next and see how it measures up.
