No parts required for this conversion except the input tuning capacitor which for me is less than $1 .......
Only advantage is being allowed to operate the amplifier with a high drive radio up to 70~80 watts PEP going into it.
Replacing the currently installed ERF7530 MOSFET's with the newer ERF9530's will produce more power output with the same input .....
I did this with my Palomar LD 450-FET amplifier and run it with my Stryker 955HP radio.
The amp will produce about 550 or so watts output.
Using my low drive Galaxy DX959 radio with 4 watt am dead key and PEP watts of 24~25 watts, the amp produces about 175~185 watts.
The ERF9530 MOSFET's are currently $4.95 each ......
The ERF7530 MOSFET's are no longer manufactured and very hard to find.
