I was wondering if someone could give me some information on this mod.?The instructions that i have on this mod. doesn't say anything about removing the biasing diodes that are on the finals or to leave them in place is there anyone that has done this mod. that can give me some information on this and what to expect on the output of the radio after the mod. Thanks.

hi there,,yes, you need to replace the bias diodes with 1n4148 diodes..also remember the diodes will have to put in reversed than what the original diode are.....................ramblingman

Thanks ramblingman for the help can i use the companion parts instead of diodes.like the en-369dr and the en-369fn. Thanks for your help.

I would not wast my money on such a mod. The power you will gain is so small it just not worth it.

OK Rick i was just curious on the out come of this mod. Thanks

i did this mod on a cobra 148gtl one time.and the radio actually had more output with the 2sc1969,than with the erf2030.might have better luck on the galaxy

Well i didn't have anything else to do so i tried this mod. done everything that was listed on the sheet and double checked every thing and never could get over 1 watt dead key and it would only swing to 10 watts so i put every thing back like it was swings to 30 watts now don't think i will go that route any more.

I have done this mod and it is a little tricky to get it right. First i would not use the ERF2030 use the IRF520N. DO NOT USE ANY OTHER IRF520 MAKE SURE IT HAS THE SUFFIX N. If you use any other it will not work properly. then just go by the dx-33hp schematic to math up all the other stuff. I get 10 watts deadkey and 30 watts swing on a dosy and 60 watts pep on my bird 43p. so you have a good bit to gain, but you have to take you time and have pateince with this mod.
