Hi Al. That confirms my suspicions in as much as..... maybe it was a..."its nearly ok" let it go. The Core has only one peak, and that is fully or nearly in. The beehive is nearly out.
I thought about the osc not tracking and looked at the coil and components there too. It is a very "Techy" adjustment for either. I am getting to the feeling that as I will not be bothering with 15, I may let it pass.
Ref the ECC85 mod, I think, for the moment I will leave till I have nothing to do... which is a long way off....
One other thing... the "Top Band" beehive trimmer in the L/O was broken, the ceramic post was broken, thus the adjust element was floating about and shifting the upper tuning point. I replaced with the RF coil trimmer and retro fitted another style on that coil.
"NEXT"
