For the ones I built with Carnhills, I simply zip tied the transformer on top of the Lundahl footprint and ran leads to the corresponding connections that translated from the Carnhill pins. I have had no grounding issues with them.

Thanks!

 Do you have a pic of that? Because this is a big traffo and it would cover the holes.

I'd have to open one up when I get a free moment. You can solder leads to the underside or find the next closest connection point to the appropriate solder pad and solder to that. It requires a little bit of creativity but it will allow you use a more compact enclosure than mounting to the case and avoid any possibility grounding issue.

Thanks!

Oh yeah, I wasn't thinking about wiring to the underside.

The compactness of the enclosure is certainly something to consider, but not a big issue for me.

I'm confident the way I mounted my transformers they will never touch the case. In the case of the Ed Anderson it wouldn't even matter since it's plastic with epoxy.

The Ed Anderson DI I built looks exactly like the Carnhill, except for one word on the front panel.

No way, eh?

I think I've built about the same quantity with various transformers.

Thanks!

I haven't made any with Sowters yet! Right now it's Lundahl, Carnhill (and Ed Anderson), Haufe, and OEP.
