Vintage speaker dating
Finally we point out location of components in the physical layout diagram.
Speakers The 2×10″ closed cabinet that came with the Tremolux is practically sized and performs well on most stages.
The two channels of the AA763 Tremolux channels are in phase and can be used together.
This is because they have the same number of preamp gain stages (each stage inverts the phase with 180 degrees).
All these things add up to an amp with less volume, less clean headroom and more sag/compression; a more forgiving tone. It feels very much like the blackface Bandmaster, the normal channel of the Vibrolux Reverb and Pro Reverb or the normal channel of the earliest blackface Bassman (AA864).
The sound is nice and clean and the tone remains relatively clean when one turns the volume knob.
All the narrow-panel tweed, blonde and blackface Tremoluxes are very valuable today with a well-deserved collector status.
The speaker is the most important component in your amp which physically produces the air waves that your ears detect as a tone.
See page How to select speakers for speaker recommendations.
A less complicated circuit means fewer things that can go wrong, less component drift issues, it’s easier to service and has less potential for noise problems.
The Tremolux is rarer than the other blackface piggy back amps since it was produced over a shorter period of time.
This will give you an full and meaty tone which you won’t get using just one channel.
