LL1620's max voltage is for PP operation, SE being 380v...

Well go with a LL9202 (6k5:16/8/4 - 525V AC. Note that that's the RMS AC signal rating not the DC supply voltage. At 380Vac signal the LL1620 should be adequate too unless you're looking at a >1100Vdc supply.

Insulation is 3kV P-S and 1k5V to core.
Check the datasheet.

This morning's response from James:



Helpful and prompt response, if an expensive one. Now it has me wondering about the way James rates current, 120 ma should have been sufficient. Looks like I need new iron in any case. 🙁 Might be a good opportunity to give the re-vamped Hammond line a shot. Maybe the 1629SEA?

Maybe so, the 1629SEA seems like a near perfect solution!

But I'm grinning from ear to ear over the 1642SE 😀
