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
1 answers Does this work with a 6V6 tube?
1 answers How many pins does a 6V6 and 6J5 tube have?
1 answers Hi: I want to built an stereo amplifier Hi-Fi with single ended audio transformers, I was searching the store and the frequency response are only 10Khz like for a guitar amp,any audio transformer with a list 40hz to 20Khz? Thanks Alfred
1 answers What kind of speaker should I use on the P-T31 transformer. I am restoring an old GE E-61 radio and the speaker and transformer are missing. Hoping this transformer will work, but not sure what kind of 8" speaker I need next.
1 answers What is the distance between mounting holes?

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.
1 answers What is the frequency response of this OT? For example, the low and high frequency -3db points.
1 answers Where are they made?
1 answers What is the primary side inductance of this device?
1 answers What are the phase "dot" on this transformer. I would guess that the red and black are in phase. In the mod102 design I think this would make the speaker out in phase with the guitar input voltage. I would like to add negative feedback to the mod102 kit which means I think means I would swap the green and black wires on the speaker connections like a 5F2A negative feedback circuit. I am guessing that the mod102 transformer is using color conventions that are similar to other speaker transformer designs. Thanks.
