Perhaps the problem would not have been resolved if there was not a world wide complaint on the 'zed. In any case, an amp that requires less than 50 watts drive to operate from 24-35mHz is, as I seem to recall, illegal to sell in the USA.
FYI of all hams...DNJ operates out of the back of a strip mall in California. The guy who operates the "store" is named Hwang, and he REALLY hates that people know this. You guess why.
It would really help new amateurs who want to build antennas to find an older copy of the ARRL Antenna book. There are too few explanations and too little data in the current editions. By old I mean say pre-1989. Cruise hamfest tables and Ebay, there are plenty available pretty cheap.
