Terry,

I would to thank you for taking the time to answer my post.
You hit the nail right on the head.
? concerning the new type zeners, they are colour coded, a good idea, are 
they still silicone and how
do you read the code (ie: resister??).
I've asked around and no one seems to know.
If you know the value of D820,D821 and D055 I could probably figure it out.

Thanks once again
