Greg,

Please do the L-L Scope verification.
There should be a Zero Crossing, as this is still a 2 Wire Single Phase Circuit, even if the Source is a Wye Configuration.

If the results show different, I definitely want to know!

For fun, how about viewing a few Load Types, such as:
  • A Pure Resistance Load,
  • A Linear Load (Induction Motor Loaded to 30% to 50%),
  • A Non-Linear Load, of >10% THD.

Greg, according to my old cross refs. the 'AM' diode was p/n 2111232. Also it was close to a 1N4003. 200v PRV but only 300ma forward current. I agree that they made them tougher as time went on.

Yup that was the one. The original little black one was not real tough but the last ones I have are something like an 18ga lead, a round gray body and a whole lot tougher.

What did you do there?

Greg,
I was at the Modification Centre 16 years (2848, 3145, 3148, & lots of other stuff) and then 14 years in production maintenance at the Toronto Plant. Retired in 2000. Still putter around with control stuff (mostly relays). What did you do?
P.S. Loved that link to the 1401 resurrection.

I was various flavors of CE for 13 years then I worked at service planning in Endicott (4300), support Specialist in Florida. In the late 80s/90s I went through the Installation planning and contract services fiasco (building computer centers and data cabling) until IBM decided they were not doing that anymore so I retired. By then I was leveraging all the construction training and experience into an inspector's license and I won a contract with the state for 8 years.
