 Thanks! for the help, i have not checked Q312 Q313. But what i did notice is the tin box in side was very hot at one end, opened it up and found that R309, R310get really hot and some of the parts around it. Can't keep it pluged in to long or it gets so hot you can't touch it, not sure if this should be warm or not sence it is a 50 ohm load resister. It has always been pluged in to my 1040.


thanks! radio tech for your help

I have a B&K 2040 that has been working fine for years, the other day i had a radio on it and noticed that the signal was very weak.  checked coax and radio and they were working good, the 2040 other functions all work good. have printed a schematic for it, just not sure where to start. I can hear the tone on all settings, but its just not very load in the speaker of any radio. I have another 2040 that i would like to get fixed to, if there is some one out there can can fix them and align them, i would be happy to send them out.
