  • Transformer Specs

    Hi, I've been searching a bit but couldn't find any specs about the transformers for the 5e3.
    When I go to the transformer shop down my street, what should I ask for?
    Yes, I'm a noob.

    PT:
    B+ secondary: 320-0-320VAC, or 330-0-330VAC at 120-125mA (330VAC is really as high as you want to go with NOS 5Y3 & stock cathode resistor, less if your trying SS rectification/unsure about the rectifier you have).
    Heater winding: 6.3VAC @ 2A, or 3A.
    Rectifier winding: 5VAC at 2A, or 3A.

    OT: Push-pull, 8.5K:8ohms, 15W rating.

    ...best bet is to go to a 5E3 specialist like Mission Amps. Transformers may cost a little more than the shop down the road (unless, of course, IT IS the shop down the road) but they're the heart of the amp.
