Hi Alex,
A big one P.Dahl does not show negative effects but a small transformer
with less iron will saturate a bit more (Gauss).
Results, higher temperature at load and no load. Output Voltages are
mostly equal. "Switch On" current is higher (fuses).
Fans rotate a bit slower and cooling is less. At first time be carefull
during a 48h contest.
In the past I used different US equipment, Collins, Heath, Drake, Alpha etc
with original PS. No negative results.
