Mains Transformers for Tube Amplifiers
LL1669A
C-core mains transformer. The core is assembled with a small air-gap to compensate for any mains DC-unbalance. Estimated
power rating 250 VA which can be increased with good cooling. Magnetic stray is extremely small if secondaries of the two
coils are loaded identically.
