? However, amateur radio guys who go shopping for a Dahl Grade E-core
hipersil transformer tend to act like aborigine guys when they go
shopping for a new phallocarp. .-- i.e., they tend to buy a larger unit
than what is called for. . . As a rule of thumb, for ssb service,
Dahl's continuous VA rating can be multiplied by three to arrive at PEP.
In other words a 1000VA rated grade-E transformer should be good 3kWPEP
on SSB.

? good point. . . IOW more copper and less paper.
