Czy ktoś zna źródło takich trymerków 60pF i 30pF nadających się do 100W PA na 2m
OZ2OE:
"With 10 W drive and abt. 26 V supply voltage I have 90 W output. The transistor is designed for 28 V and will give more than 100 W, but I had to settle for a little less. The reason is, that my transformer/ capacitors was a bit underrated and could not deliver max. current without ripple "break through". So by reducing the output voltage, the regulator had a little more headroom to work with."
