Need to buy a part

[Michael Chisena]

Hi all,
Still working on that Astron 70 amp PSU.
Seems the OEM used an 'under sized' SCR as part of the crow bar circuit.
According to the web nobody offers this part, and if they did, it still was not enough SCR to shut this thing down in the event of a runaway.

Anybody have an SCR that is a good drop in for this project? And do you want to sell it.

I am not adverse to drilling new holes in this thing, so if you have a big stud mount part, that is ok.

Here are some 'in process' photos.

Thanks
Mike
