A Local Tranny winder made me OT and PT for plexi clone (schematic
from hoffmanamp.com) I built. The Vs are way off (500 on EL34's plate)
and OT is mismatched as well: instead of 3.4 K it gives 2.5 K into 8
ohm load. I'm thinking to haul these wonders out and ( if ithere is a
power tube that can handle such values as noted here) use then in a
new amplifier. Q: Anyone know of an output tube that likes 500 B+ on
its plate while looking into (PP) a 2.5 Kohm load? To get the plexi
back on track are there any Tranny winders one would recommended?
Mercury Magnetics, Heyborer, Hammond

He wants winders, not mfgrs... and you misspelled Heyboer.

Peter Dahl Co. in El Paso, TX does lots of this kind
of thing... it ain't cheap, at all.
