Does anyone have construction and electrical details on the 4:1 transformer
used in the tank circuit of the HF-2500DX amplifier?  Number of turns, wire
size, toroid size, core material, inductance, etc.? Also, are there are
other 4:1 xfmrs that have been designed, suitable for QRO use? I'm
interested in 160m and 80m designs, mostly.

Tnx,

Jim W8ZR
