Pulling RF off the H-amp?
#4
I suggest right after the HP-Filter.
Lower cutoff (-3 dB point) is 3KHz, and 50/60 Hz are attenuated significantly.
A 430-470 Ohm at that point is acceptable - this gives an attenuation of 20dB at the outlet.
Remember first stage amplifier ~ 0-30dB
Will we hear about the result? Wink
