Christie Transmission System

Recommended Posts

The organ in the church where I am DOM has a Christie Multiplex transmission system which has failed. There are 2 racks of circuit boards, one which transmits the signal to a receiver unit in the organ, & another which takes care of the departmental & general pistons & memory levels. Both are protected by a 5A delay fuse. By a process of elimination it seems that the power supply board in both racks is causing the fuses to blow. My question is, do any members have experience of this system and/ or a circuit diagram?

The Christie system was designed by Vic Hackworthy who is now retired, & I have been unable to contact him.

Any help with this problem would be greatly appreciated. It seems a replacement system will take at least 3 months to design & fit! The organ in question is a 4 manual with approx 53 speaking stops.

Another possible source of knowledge would be the Village Workshop team/Andrew Ray (ex-HNB Works manager and seems able to turn his hand to anyting in the organ world). Try David Stalley on 01371 811185.

Sounds like Redland Park URC. A fine, fun-to-play organ. I hope it feels better soon.

You are indeed correct!

 

Thank you to those members who have responded with help, and as a result I have been able to speak to Vic Hackworthy.

The main problem seems to have been the failure of 2 zener diodes but what caused one to fail & then another 2 days later remains a mystery. Further problems have now emerged with the general cancel piston & Gt.& Ped Combs Coupled, but at least the organ is now playable!
