HAMMOND O/P 5,000 Ohm C.T. 30W Speaker
taps 4-8-16 ohm & 70V. This transformer could be used in a typical Vox
AC30 configuration i.e. 4 X EL84 but special provision will be required
for filament supply. We suggest a 4A supply min @ 6.3V or use a 12.6V
or 25.2V supply. Recommended H.T. supply about 300V. Weight: 2Kg
Mounting centres 2" X 2.69" can also be used for 2 X 6L6GC, 6V6 or EL34.
HAMMOND O/P 4,300 Ohm C.T. 60W Speaker
taps 4-8-16 ohm. We recommend this transformer for anyone wanting to
build a Guitar or Hi-Fi amplifier in the 60W range. Max I per side
318mA. For guitarists this transformer is an excellent choice for 2 X
6L6GC, 807, 5881, EL34, 6146B, 6550B, KT88 for a truly 'Classic' style
amp. For a Fender style amp simply leave the screen taps insulated.
Weight: 3.63Kg, Mounting centres: 2.5" X 2.94".
HAMMOND O/P 1,900 Ohm C.T. 120W Max I per
side 403mA. Speaker taps 4-8-16 ohm. For those who want their 'Blues' at
80-120 Watts, this is ' the one'.Suits all 'Classic' 4 or 6
output tube designs using 6L6GC, 5881, EL34, 6550B, KT88 in push-pull
parallel. Weight: 6.35Kg, Mounting centres 3" X 3.31". Exceeds
Broadcasting and Hi-Fi Specifications.
