Good morning gang...

My 28V power supply for my SCR-274N system isn’t quite stout enough so I’ve
been using a standalone HV supply in place of the BC-456 dynamotor.   I’m
planning on getting the 274 on AM and would like to use the dynamotor
(which I’ve rebuilt and runs fine).

 I have a 29-0-29 50A transformer in the pile that I’m planning on using
for a new supply (variac controlled) to power the dynamotor.

 Does a dynamotor need a regulated input?   I recall reading that if the
supply for a dynamotor is stout enough a regulated input isn’t needed,  but
I can no longer find the reference.

Thanks!
