    Hi guys, I have a VS100 combo that is DOA and not wanting to be revived.
    Power transformer is good and will repurpose it.
    Would anyone know specs at all.
    Other wise.....
    It has a high voltage tap that powers the single 12ax7 (approx 240vac) with a protection fuse of 250mA, so the current capacity could be good for 3-4 12ax7s
    The 6.3v heater tap may be only good for one 12ax7 or relay power, has a 250mA protection fuse
    The 64v CT that powers the main circuit has no fuse, but a fusible resistor rated at .5w
    Put through a quadrupler could get approx 350vdc to power a pair of small output tubes, maybe around 120mAs
    Thoughts

    Power ads so you need to know how much you have to work with . The heaters take the most the plates is next what tubes will work with it so what do you plan on building

    Bassman/JTM45 circuit with 6V6 or EL84 output.
    Heaters will be a separate PT.
