  • Tweed Deluxe PT OT recommendations?

    I am looking to build a tweed deluxe 5e3 clone. In looking at Hammond's website, they list the 290AX PT and 1750E OT for the tweed deluxe. I have heard others say go with the 290BX PT and 1750H OT. I am trying to capture the tone of the original 5e3's. Anybody use either of these or would like to weigh in with their thoughts. Any recommendations on other manufacturers?Thanks!

    Hi Jman and welcome to the forum

    5E3 traditional PT is:

    325-0-325 HT winding @ 70mA (yes that's right - 70mA)
    6.3V heater winding @ 2A (if you get a PT with 3.15-0-3.15 heater winding, that is handy because you can easily elevate the heater CT to the output tube cathode(s) to quieten any heater hum. But if you can't find such a PT it doesn't matter because you can use 100R artificial grounds (or a humdinger pot) off each end of the 6.3V winding anyhow)
    5V rectifier winding @ 2A

    Traditional OT is 15W PP 8k primary - 8R secondary

    Any manufacturer making you something with those specs will sound pretty close to the original 5E3 if you more-or-less follow the rest of the original 5E3 specs.
