Push-Pull Output - General Purpose (125A-E Series)
UNIVERSAL PUSH-PULL
"CLASSIC" TUBE OUTPUT TRANSFORMERS
? Designed for general purpose or replacement use in push-pull tube output circuits.
? For single ended use, see our 125 SE series - optimized for single ended tube output circuits.
? Frequency response: 150 Hz. - 15 Khz (+/- 1db max. ref. 1 Khz)
? Open style with minimum 5" long primary leads, secondary solder lugs for convenient secondary connections.
? Tables provided with each transformer listing 90 pre-calculated impedance ratios.
? Primary impedances from 1,200 to 25,000 Ohms and secondary impedances from 1.5 to 15 Ohms (see chart below).
