SINGLE-ENDED
"CLASSIC" TUBE TYPE - ULTRA-LINEAR
OUTPUT TRANSFORMERS
•
Over designed for single ended tube output circuits
(triode, tetrode or pentode tubes).
•
Enclosed (shielded), 4 slot, above chassis Type "X"
mounting.
•
Frequency response at least 20 Hz. to 20 Khz. at full
rated power (+/- 1 db max. ref. 1 Khz.)
•
Insulated flexible leads 8" min.
•
25 watt units include a 40% screen tap for Ultra-Linear
operation (if desired). 75 watt unit does not include screen
taps.
•
High quality laminations, (M6) grain oriented silicon steel
•
75 watt model secondary, has easy hook-up taps rather
