That is nice ,Yes Daniels right, the 3" boiler on the Jensen would probably run your new Stuart, just get an auxiliary valve to screw into the boiler. Or you can run it off of a variable speed aquarium compressor. Re:reducing the power to the Jensen #20, just buy a variac, they've really come down in price since I bought mine, look for a 2k watt to cover your power future needs for a long time. Thick walled silicone tubing (medical grade) works well for me.
