ST-70 Power Transformer Info

rudy129 · 10th March 2007, 05:49 PM

I came across a power transformer that was in a Dynaco st 70 that does not have any familiar numbers on it to me. Was wondering if anyone has a clue as to who made this? The numbers stamped on it are; 464006
GT 9790
7578826

I was able to find that 464006 is a Dynaco # that xreferences to PA060.

Look at the DynaClone replacement data sheet. See how that matches up with the trafo you have.

"757" is the EIA code for "Grand Transformers, Grand Have MI".

8826 is 1988, week 26.

Did Grand manufacture this for Dynaco or is this a "drop in" replacement? Better, worse or the same as PA060?
