RX:
C408 - Change to a .22uF, 50 volt or higher
More highs?
C410 - Change to a 330 or 220pF, 50 volt or higher
This unit has a strange always on ANL circuit. Because of this I'm not sure if C407 also needs to be made larger without having an actual radio to play with. This cap also feeds the AGC line. If the receive seems to be lacking lows after the conversion, change C407 to a .1-.22uF, 50 volt or higher. Let me know a365 after you modify the radio and I'll edit this post accordingly. Thanks!
TX/RX:
C511 - Change to a .22uF, 250 volt or higher
If the squelch acts sluggish, lower to a .1uF
C513 - Change ta a 22uF, 25 volt or higher Electrolytic, observe polarity
C601 - Change to a .22uF, 250 volt or higher
TX:
C504 - Change to a .22uF, 250 volt or higher
More highs?
C502 - Change to a 330 or 220pF, 50 volt or higher
C905 - Change to a 4.7uF, 350 volt or higher Electrolytic, observe polarity
Disable AMC - Remove C604
Variable power - Add a 50K, 2W potentiometer in series with R904
More peak power?
C912 - Change to a 1uF, 350 volt or higher Electrolytic with the negative lead towards L907
