Shorted primary?

10/25/2004 5:15 PM
Mark Lavelle	Shorted primary? I think the 270EX in my Verberator may have a short in the primary. My secondaries are way low even with all the tubes removed (e.g., under 80 VAC across the red leads), and I've already been through a couple of fuses on the primary side after not finding any shorts on the secondary side of the circuit. Does anyone out there have a 270EX they can measure? I'm getting less than 3 ohms across the primaries (a 270DAX I've got measures 5.2 ohms). Any other suggestions are welcome, too, of course...

Shorted primary?

I think the 270EX in my Verberator may have a short in the primary. My secondaries are *way* low even with all the tubes removed (e.g., under 80 VAC across the red leads), and I've already been through a couple of fuses on the primary side after not finding any shorts on the secondary side of the circuit.

Does anyone out there have a 270EX they can measure? I'm getting less than 3 ohms across the primaries (a 270DAX I've got measures 5.2 ohms).

Any other suggestions are welcome, too, of course...
