It’s definitely been entertaining rereading this thread, even if it has been several times.

The line frequency was fast even with the original decoupler. The picture stability in #90 didn’t last very long, and I’ve never been able to get it back to that stability, and even then it wasn’t the most stable. The cap in place is now at 4.7 as this is the closest I could get. If needed I can get two more 2.2s and put them in parallel - and properly this time.

I’d figured out the BECs on the BC148 and it was back to front, E and C had swapped over. As I say was recommended a BC108 which has the right BCE configuration. This is in place and appears to be working just fine.

Definitely does help as I’d be completely llost otherwise.

Thanks
