What is the max current on the primary?
Asked by Anonymous on February 7th, 2016.
It doesn't appear as though we have that spec available for this transformer in particular. Both Hammond 8 Watt versions 125C and 125CSE have a max DC bias of 60 mA. Someone might consider that rating as a ball park reference for similar transformers, but you may want to consider the Hammond's instead of P-T291 if you need a guarantee on the rating.

Will this work on my phico 87 with push-pull 45's?
Asked by Anonymous on June 29th, 2017.
Unfortunately we are not techs and can not advise you on this inquiry. I would try to get the specs on the transformer in your Philco and compare them with this transformer.

Are you able to provide me with the primary side DC resistance, (not impedance) I would like to know what that resistance measures from the centre tap to each side.
Thanks

I'm somewhat of a newbie at this and want to know if this output transformer would work in a Truetone/western auto supply-- D711. Thanks

Unfortunately we are not amp techs and do not know if this is compatible with a D711. You may want to contact a tech for compatability.

Is the brown wire center tap for primary? No drawing shown for the primary side; rather 2 drawings for secondary connections! Thanks!

Will this work in a single ended guitar amp, design calls for 4k primary and 8 ohm secondary. The tube complement is 1 12at7 and a single el84/6bq5.

It may work, but the P-T31 sounds like it may be a better fit for your application. https://www.amplifiedparts.com/products/transformer-output-8-w-single-ended
