2 answers Can this transformer (P-T31) be used to replace a Hammond AO-24158-D in a AO-44 reverb amplifier.
Asked by Anonymous on July 10th, 2017.
We are not techs and are unsure if this will work in the AO-44. The best thing to do is compare the specs of the P-T31 with the AO-24158-D.
no the AO44 is a push pull type amp it uses 2x ecl86 tubes but any output transformer that is push pull type and works for 2 EL84 tubes (ecl86 has 1/2 of a 12ax7 and 1 el84 in 1 tube) should work i think Hammond universal push pull 8w would work plus offer different speaker outputs, the Ao44 was 8ohm speaker only
2 answers I am replacing a Transformer whose primary leads go one to a filter cap and the other two 6A Q5. Can you please tell me how to wire the red and blue also which of the speaker wires is positive? Thank you very much
Asked by Anonymous on September 1st, 2017.
Red goes to B+ which is the filter cap, Blue goes to plate of 6AQ5; Not sure which of the speaker wires (Green/Black) is positive, but it shouldn't matter as this is an A.C. output and polarity is not critical. It will function well either way, but if you are concerned about the phase of the speaker as compared to other speakers in the system, hook it one way and try it, is it sounds good, leave it; if it doesn't, switch green and black. If the amp howls with no mic or guitar connected, switch blue and red. 6AQ5 Plate is Pin #5.

1 answers What would you recommend as the best sounding speaker for this transformer?
Asked by Anonymous on March 28th, 2017.
Since speaker selection is a very personal choice, it is hard to say what is best for this transformer. I would look for a low wattage 8ohm speaker. For an economical solution SKU: P-A-MOD6-15-8 would be a good choice. If you wanted a large speaker SKU: P-A-C10R would be another option.
