For anyone else on the list who is interested, I have found the scans of the circuit diagrams for the 40CT1 and 45CT1. It's about 500k all up, plus another 300k for the PDF manual. If anybody else wants a copy I'm happy to email it to you and if anyone wants to stick it on a web-site for all to download free I'm happy for that to happen as well.
