    Mikes repair videos

    Well since we got off topic, I'll add that I've heard good things about Doug at custom cb. Also q5 is supposed to do good work.

    Galaxy No am tx but ssb works fine

    It's fixed!! Thanks Andy and ext13 as well. So when you pointed out that voltage was magically appearing and disappearing it really got me thinking. I decided to focus on the area that you(andy) had made a line/marker to , the r264 ,265 junction. The wiper of vr14 had correct voltage, ok good...

    Galaxy No am tx but ssb works fine

    I see what your saying about the voltage appearing at q56, I didn't catch that. I will be definitely looking hard into that area. Then I will be tackling the other things you mentioned. There were some mods done to this radio by previous owner, but all that stuff is long gone. I have already...

    Galaxy dx77HML no AM transmit but works on SSB

    Yes I am following Andy's instructions very closely. I was just curious if the op had ever figured out what was wrong with his radio being that I am experiencing the same thing. Didn't mean to get two threads going on the same thing. No voltage getting to collectors on driver or final in am...

    Galaxy dx77HML no AM transmit but works on SSB

    Wouldn't ssb also not work if they were bad? Both have been replaced though.

    Galaxy No am tx but ssb works fine

    I have 8 volts present at vr14 in am and fm with adjustability. Then after that it just seems to get lost. I can check out those d84 to d87 diodes. Thanks a lot.

    Galaxy No am tx but ssb works fine

    I did already replace q53. Also voltage can not be adjusted with vr14 in am only in ssb at q53. Same with q56 and vr17, only able to adjust in ssb. Same with rf power knob. Just checked fm, it is dead as well. I'm going to find q58 and check it now. Thanks

    No voltage on collector for q55. Voltage missing on q53 base and emitter. Q53 has correct collector voltage. Thanks

    Hi all, New guy here, but have been around cb radio all my life. Hoping someone can help with this issue I'm having. I have a galaxy dx95t with the ept6900 board. It lost tx on am but ssb is still working. No voltage getting to collector of q54, meaning no voltage getting to driver or final...
