    Does anyone know of a commercial power supply that will output both AC and DC as well as regulate voltage and amperage? Or would I need to buy both a AC and a DC PS? Right now it will be used to charge capacitor banks, but I would rather buy one rather than need a better one for a later project. As such DC is more important then AC, I would like to go up to 100v or so.

    The majority of power supplies are either AC or DC but not both. Some AC sources
    may be able to do DC.

    You may be able to find an amplifier that goes down to DC. Take a look at Kepco
    power supplies (BOP series).

    A Variac ,120V AC in gives 0 to 130 v out, un regulated and hot. Feed it into a DC PS un reg and have 0 to about 175V DC. One comercial PS DC only excellent regulation 1 KW. 1 to 120 V & only $ 4k. do you want two ?

    You have to be careful with a Variac. It provides no galvanic isolation and so presents a lethal shock hazard.
