MS9 that curls in at the sides, picture goes out

Post by nem »

I have a MS9 that curls in at the sides and then snaps back:





It also does this:





(sorry for the crappy video, I was moving to have a better angle on the monitor. The picture actually came back soon after, right when I was about to pull the plug on it)

The electrolytic caps have been replaced, the hot was swapped (it had a D1887 before, I put a legit 2SC4692 in). B+ was stable at 115.3 (24khz). It does this in 15khz as well.

EDIT: I cranked B+ to 119V which it's supposed to be at, I think. Didn't make a lick of difference. Had it running for 10 minutes, then the picture went out accompanied by a high pitched whine.
