Universal 50W push-pull Output Transformer: SOLD OUT
This universal, push-pull output transformer has been specially designed to
offer the most common impedances used in guitar amps. Although rated
for 50W (full audio bandwidth) it can be run at lower power levels too, of course.
If the frequency response is limited to the guitar range then it can be also pushed to 100W.
It
offers two primary impedance options; 4k and 3.25k ohms into 4, 8, 16
ohm speaker taps. By doubling the speaker impedance you obtain two new
primary impedance options; 6.5k and 8k ohms. It has an extra heavy-duty
primary coil rated for 160mA per half, allowing it to be used even with
KT88s in Class A! It can be mounted drop-through or upright using the
end-frames. Made in England. Perfect for 18W, 36W and 6V6/EL34/6L6/KTxx
amps!
(Note; although the label reads "UL", this is not a true ultralinear tap, it is a labelling error.)
 
Suggested applications:
8k= 2xEL84, 2x6V6
4k= 4xEL84, 4x6V6, 2xKT66, 2xKT88 (triode mode)
6k5= 2x6L6, 2xKT88 (tetrode mode Class A)
3k25= 2xEL34, 2xKT77, 2xKT66
