Cool stuff, I'm glad this thread is taking off despite our small numbers. Steve, I'd be interested to see what you'd come up with for the SFI drivers. I currntly have the ECR-500 stripped down to it's pieces with a view to modding and replacing the old foam and cable etc.
Fungi, thanks for the offer. I downloaded the service manual a while ago as I've been looking for some ECRs on and off for over a year now so I'm set.
