I will have to order those parts will this work?

Still working on getting the driver transistors out of the circut, desodering is difficult with what i have. Are they bad anyway should i just cut em and test the resistance?
Add new solder to all 3 pads. Lay the iron across all 3 pads so all are heated together. Pull the transistors when all are hot.
So remove them from the board and the mesha rail now and then test the resistance on the ps fets?
Perry quick question on my board all the resistors R180-R191 are color coded for 15ohms i beleive, on the scheme it has 22ohms for R180,181,182,183,184.....Would this make a difference, or am i not reading something correct??
after checking them again. i only get infinite resistance on Q9-12, Q8 nothing Q7=409 Q6=408 Q5=409?
You should not be doing anything on the output side of the amplifier.
Q8, what do you mean by nothing?
For Q5-7, do you mean 409 ohms?

I couldn't get a reading of resistance from Q8, yes I think so my meter is really bad. It was on 2000k and read 409ohms?
I just purchased a better one yesterday so I can give u more consise readings. I couldn't get any resistance to show on the meter, it never changedwhen I touched the PS fet anywhere. I can try again when I get home.
Ok so this is the best description i can give you, the fets Q9-12 have infinite resistance on the 20k setting, is where i can get a read, the ps fets Q6,5,7 have infinite on the 2000k setting, and i still cant get a read on Q8 on any of the setting my reader has, i held it on for awhile. I did remove the soder from the board where the drivers were, not sure if it makes a difference but i dont want to leave anything out.
Are you using the correct term? Infinite resistance means that the meter reads the same as when the probes are in contact with nothing but air.
no i am not, sorry. And thanks u teach me something everyday. then Q8 has it, and if i set the meter to 20k then all of them are infinite. on 200k Q9-10,11,13 start at 15.0 and rise then on Q6,5,7 is 128.5 and rises steadly. ?
When the reading increase, do they eventually go to infinite resistance (whatever your meter reads when not touching anything)?
If so, how long does it take?
