Wyvern Electronic Church Organ Information Sought - UK Vintage Radio Repair and Restoration Discussion Forum

pmmunro · 13th Feb 2016, 7:02 pm

Can anyone help with information on a Wyvern Electronic Organ, Model C340, dating from 1993 please? The tone generators are based of Bradford University technology and these boards may even have been supplied by the university. They use a significant number of Plessey MSI circuits, so I hope they stay working.

I have general layout diagrams but really need circuit diagrams and, if possible, an overall wiring diagram - although I suspect this may never have existed.

I have tried contacting Wyvern but it seems that the company split in an not entirely amicable way and although I have been referred to one or two individuals whom it was suggested might be able to help, I haven't been able to get the information I need.

This organ has always been maintained by a man who lives very far away and who is becoming increasingly retired. He has supplied some basic information and promised more but probably finds it difficult to find the time.

PMM

Is it no longer officially supported by Wyvern themselves (Graham Lord)? Have you tried Royston Orme a.k.a Ormatronix? Might be worth a post on the Organ Forum, although US-centred there are some knowledgeable UK readers.

Much of the R&D work on these was done by Tony Koorlander, whose profile is readily available on the internet. He might be able to give you some pointers.
