PT Wattage Testing

Post by steviea55 »

Ok,I found a "non-working" Scott power amp. It had a Woodfard-Schumacher PT which looked good to my eyes. After removing it I connected a Variac to the Primarys and set the voltage to 10 volts. I connected a DVM to the Secondary (red wires) and set it for AC volts. I now have 5 volts on the coil and 2.3 on the center tap. That looks good. I have no other wires other than the filament tap(Green Wires) with this model. Here are the #'s on the PT 024-1140-008 I know that 606929 is the mfg. code and the date. In this case 29th week of 1969. It looks like I have a good PT for a Small amp with a bridge rectifier using diodes. Here's my question. HOW DO I TEST TO FIND OUT THE WATTAGE POTENTIAL OF THIS PT?

I think the capacity will be rated in max amps for each secondary. You would then need to calculate if those are adequate for your needs.

Maybe they can help you with the specs if you are nice to them:

If it says "Vintage" on it, -it isn't.
