Hi David.
This circuit is also used on the V510/530 and I think the Astra as well. On the V510 & V530 the upper decoupler (C46 on the V530) was changed to 1800pf and is an official mod for the 410 through to the V530. The mod is in the V530 service manual and was in Murphy News sometime in 1960.
Today I managed to drill out two damaged cores and free off the rest that were OK. I did a quick spot alignment with reasonably good success. Tomorrow I'll do a full realignment with a Digital signal generator for 100% accuracy.
