    Hello,
    Thank you, just fantastic job finding this information and sharing it.

    Could you please find videos explaining how to identify unknown Power & Output Transformers?

    I have 2 - sets of Baldwin Transformers from Hammond Organ 4 - 6L6 Power Tubes. I would like to know how to identify the wiring and be able to test them and know what their capabilities are!!!

    Thanks again!!!

    An "Integrated Amplifier" means it has a pre-amp built-in. There are plenty of tube integrated amps. If it does not have a pre-amp, you will need an external pre-amp for most turntables.

    Note that the pre-amp section is most important from a noise point of view. So, IMHO, a tube pre-amp connected to a solid state amp makes (some) sense, (although you will not get the full "tube sound"), but connecting a solid state preamp to a tube power amp makes no sense to me.

    One thing (and this part is more a question for discussion, not an answer) is that combining a modern tube pre-amp with a vintage tube power amp does make sense to me.

    There seem to be lots of cool tube pre-amps available at low cost, but the vintage power amp hardware can be found at a good price, even if you allow some budget for repairs/modernization.

    Some of the modern tube pre-amps use modern solid-state power supplies, but stay pure tube in the signal path.
