Truth be told....I have no clue.
The guy I bought the radio from had a receipt for the peak/tune install of a connex. ME, I just tried to keep the echo/reverb set at a level where I sounded clean without being in a tin can or echoing like a bad football announcer.
As for the wattage...I had the SWR meter fixed, and the CB GUY scoped it and said it was putting out 37ish. Whether or not he knew how to read the scope?????????? At least he fixed my meter light!!!
I just know I got a lot of comment on how clear my BIG RADIO sounded. Running a telex roadking mic, and having a voice like Jim Reeves probably didn't hurt.
