I need to replace the power transformer in a Magnavox amplifier 93003-00. It is a stereo push-pull EL84 circuit. The schematic is attached and some pictures of the defective one are shown. The schematic shows the screen voltage to be 300. What other info do I need to find a suitable replacement?

Thanks,
Rich

Thanks so much Greg! That is exactly the part I need. Anybody have one for sale?

Are there other products that might have a similar transformer?

Thanks Greg. Do you know if the Magnavox 8800 (8802) series amp also used this power transformer? Do you have access to that Sams?

Hi Rip ,

I have a vertical mount power transfomer that will work fine for $25 + $14 for shipping , or i have a exact power transfomer in a magnavox 9302 amp that i'm working on that will sell for $45 + $14 shipping . I will put the vertical mount in mine if you want the original transfomer .

Be sure you check the hum balance pot , i have found them shorted and have taken out the power transfomers in two diferent magnavox amps . I have spare output transfomers for you amp if you need them , have seen several open before when the power transfomer burned up .

The magnavox 8802 , transfomer doesn't 5 volt winding for the 5U4

Perfect! If the original is in good shape I'd prefer it over the vertical mount. I will PM you to arrange payment.

Thanks,
Rich
