Are those actually silicon? I always suspected they were a selenium stack, and never trusted them.

shango066 also tried one in a roindie, and it fried in 20 min.

so I tend not to trust them.

if anything SS, perhaps this or something like it.

I never had one fail, so I don't know if they had a string of silicons or selenium stack. If I knew they were selenium, I never would have used them, knowing that the focus rectifiers were.
I used the EDI brand, not the ECG.

i did a quick look, but sadly any compatible EDI brands are quite unobtainium.

So the choices fixing it to the original spec, which I will try first, then go with that huge 1A 40kv SS diode later if all else fails.
