Ok, brings up a good question, I fed the 12 volts section with the 10 volts supply, would this drop of 2 volts cause a major drop in the audio out section? Mathew Matt, no it is not worth the trouble. Just feed only the 10 volt section. That will disable the audio. The 12 volts

I am working on a Mastr ER41 receiver which has low audio output. WOndered if anyone has run accross this before and where to look. I have not done any trouble shooting at this point, but thought by chance if is was a common problem someone could point me in the right direction. Thanks.

Matt, it is likely the audio output transistor. ER41 comes in two versions. One has about 2 watts of audio from one transistor. The other has two transistors and about 10 watts out. In both cases the transistors are mounted underneath the receiver on a tab on the heatsink. If yours has

Ok found all of that, this is the E version. I checked the voltage on the transitor, its about 1/2 of what it should be. I just wonder if this low audio will hamper the use of it any in the repeater situation. The sensitivity of the receiver is excellent, at .17 Uv at 12 DB. I am using
