Does any body happen to know what the 2 diodes are that are in this controller/ There are 2, D1 and D2, but the manuals only give a CDE part number.
1 is listed as a zener, and another a 100 PIV diode. That's all the info on it I can find.
Thanks for any help
Has anyone used or owned one of these.

The specs seem good and it's Made in England (Great Britain), There just doesn't seem to be a lot of information as far as reviews for it. One guy on utube has a review, that's...
I had my counter set to MHz at first, switched to kHz showed the signal frequency. That got me to looking at the data sheet a little more and I see how you got me there. I don't have a very good knowledge of what the ic does, so thanks.
So with all that's going on with the 5082, it looks like...
With the scope on pin7 of the 5082P and pin7 of the 2081AP, they connect, I get this image. It's a snapshot, best I can do. But it does appear to have signal unless I'm mistaken. No voltage or freq showing on pin7 though.
I found the 5082P datasheet. Only it's in Japanese I believe. Also this diagram.
Looks like IC5 (TC5081P) comes in to play as well. I've just been tracing back on the schematic to anything tied to the blown capacitor I had (C103).
