Perhaps a little off topic subject.... Does anyone know of a source for
25 Ohm, 0.10" diameter flexible coax cable? I am in the process of
converting a 500 Watt Quintron QT-7095 station to 10 Meters. The RF
amplifier uses four 28V MOSFET's matched to 50 Ohms with a Guanella 4:1
transmission line transformer. Unfortunately, the amplifier is tuned to
36 MHz. The Guanella transformer gets very hot at 29 MHz while output
power is low. It looks like I may have to rewind it, but am unable to
find a source for 25 Ohm mini flexible cable. The closest thing I can
find is semi-rigid, which is no good for this application....Alex
