Delta Prime replied to the thread Television reception antennas farce....TV reception antennas are nominally designed for either 75-ohm unbalanced or 300-ohm balanced standard impedances. An antenna’s... -
Martaine2005 replied to the thread Amplifier biased too hot?.Most amps I’ve serviced have trim pots. I see absolutely no reason why you can’t keep them there. After all, a trim pot is just a... -
WHONOES replied to the thread Amplifier biased too hot?.Hi Tom. I'm pleased that it worked out for you and your amplifier. The procedure is fairly straight forward but, if you are not familiar... -
Ttom1970 replied to the thread Amplifier biased too hot?.Had to use a third resistor in parallel on one side to get it good as I didn't have the correct values needed so ended up with...
