hello : I need information about an amplifier called Tornado 100, as he says in his box, is 2-30 Mhz, of 250w SSB, 100w CW, works with 12 vlt and takes 2 transistors MRF 455. It works very well with my FT-817 in 10/12/15 and 20 mtrs but in frequencies more low I have an imbalance in the entry. Anyone know this amp? can found the circuit diagram of this? 73s Fred LU6KK
