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

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.

By looking at the spec sheet above, this transformer should work with 6V6, 7C5, and 6AQ5/A tubes.

Both a 6V6 and a 6J5 tube have 8 pins each. If you are asking how many used or active pins, the answer is different. A 6V6 is a pentode. A 6J5 is a triode.

Most of our current transformer stock will be leaning towards guitar amplification. I would suggest checking out the Hammond offerings as those would have the best chance of meeting your needs.

From what I can see you would want to use an 8 ohm speaker with this transformer.

Yes, this transformer should work with the El84. We use this transformer with our MOD102 Kit: K-MOD102.

The maximum DC bias depends on the tube being used, the plate voltage, and the value of the cathode resistor.

The manufacturer does not provide a maximum current specification. However, our MOD102+ amplifier kit, runs the P-T31 at a current of 35 milliamps with a plate voltage of 242 VDC.

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.

Paul Ryan - September 4th, 2019

I'm using this transformer in the recording amplifier on a Lear Wire Recorder, which is very rare, and it is working perfectly!
The second one is a spare, as I have 2 of these wire recorders.
This product is excellent and everyone involved in my purchasing and receiving it were excellent!

Eli Attias - April 6th, 2019

Suprisingly good sound from such a small and cheap device. very pleased.
