It tunes from 50 MHZ to 220 MHZ so it covers channel 2 to 13 which includes the FM band that is between channel 6 & 7. The tuner input is 300 ohms so I’m wondering if I can use a ballet coil to match this amps output to the 300 ohm input of my radio. What is the impedance of the output of this amplifier. If there is something better that I can do I would appreciate any and all suggestions.

I also want to have a 0 center tuning meter. Does anyone have a circuit I can use for this? I have a nice Zero center analog meter movement. I would post pictures if I knew how

Do I change the capacitors to higher value such as 1000 pF?
