Thank you very much you 2 the 2166 was bad on one radio and the diodes on the others, you guys nailed it!.

I thought bias diode for the driver was d69? I will check all3 d69 d112 and d68.Cleaned vr 11 well, it's working checked it with an ohm meter through its range,.I was thinking maybe a disc cap electrolytic or resistor in the neighborhood may be at fault but don't know where to start. .Need to...

Have a few Galaxys with the same problem the driver bias is too low like 35 ma max can't get the 50 to 75 they want .2 of the radios are galaxy 99v's and 1 dx88hl they all work great but vr11 is maxed and only reads 35 ma the final vr10 and vr 20 I can get set correctly on all 3 but the driver...

The 2sa1869 transistor was bad but the 2sb827 checked good but i replaced it anyway,forgot to mention i also replaced i believe it was q37 that was a 2sa1869 replaced with a 2sa473 i did all this and that is when i got transmit back . Please help me get recieve.

I was transmitting on am with a wilson 5000 antenna ,swr was 1.3 all was fine till i lost am transmit.Went to sideband mode and transmitted fine for a few minutes then lost recieve audio and sideband transmit all at once .I replaced q54 and q55 and now i have am transmit and sideband transmit...

Dug this radio out of my box and would like to get a little more tx out of it,put a 1307 final in but it is still weak.Have a realistic preamplified power mic on it already.Need to have more pep forward anyone familiar with this chassis and how do i polish this turd.thanks

Personally i loved my first galaxy dx 959 after it was tuned by me talked all over the world on my shakespere pogo stick 318gbt 20ft off the ground at the base,in fact sold it on the air to a driver passing thru traded it for his hr2510 uniden which i still have.Really wish i wouldnt have traded...

So whats right on the bias what the tech on the phone at galaxy tech said or the tech that emailed different readings,Mudduck do you know the answer or how bout you Robb.You guys seem very educated on these.Mine is working great on 4 volts but i have a problem with two different techs giving...

For everyone the Galaxy tech said dont worry about the ma readings on the bias on tp7,8,9 just set vr 12 so l37 has 4 volts and set vr10 so l33 has 4 volts channel 1 usb tx on the mosfet only chassis.Thought id post this it may help someone trying to get this set.

Okay i'll leave the mosfets.Doing my full alignment as i did on the old transistor dx959 pulled jumper board checked ma between tp7 and tp9 and got 3.5 for transistors this was set at 50ma and between tp7 and 8 i get 1.8ma on the old radio i set it at 100ma.Should i just set the gate voltage to...

my 2sc2166 drivers and 2sc1969finals are original new ive been sitting on them for awhile and thought i would like to put them in my 2011 mosfet dx959 because it doesnt seem to do what my old bipolar final dx959 did for output pep.I will try what is suggested and do appreciate all the info .I...

noticed c222 by q52 is also missing on the mosfet version.

I have some extra nos 2166 driver and 2sc1969 finals and would like to convert my newer galaxy dx959 that has irf520's to them .I know there are 2 diodes d90 and d92 in directly front of mosfets need to be reversed but what else did galaxy change.The reason i would like to do this mod is i had...
