And with enameled bell covers and base mount.?. I'd remove the covers and see what internally grounded means. If the internal ground contact is visible and it didn't satisfy me I'd add a lead that could be soldered.

Too bad there’s no 5v tap, would actually make a decent PT for a low wattage tweed style amp.

I've seen power transformers with internally grounded center taps. You have to hope the mounting bolts don't come loose.

Is that a thing?

Transformer has no center taps?
This is the power transformer I pulled from an old tube reel-to-reel unit:

Two wires for the primary, two wires for the HV secondary, two for the LV secondary. No center tap wires.
Here’s the schematic (printed inside the unit):

The PT is at the bottom, just right of center; you’ll note that it shows both secondaries have grounded center taps. So what gives? Are the center taps internally grounded? Is that a thing?Tags: None
