Question about Rockford Fosgate 100a2 Car Audio Amplifier
I have an old school punch 75 pre hd that has a bad crackling in 1 channel. It was both channels. I replaced all output fets, all the ao6 and a56 transistors, all emitter resistors and 1 side works great but the other does not. The side that does not work will not bias either. I did find a very burnt resistor just in front of the transformer but don't know if it is part of the chaneel or causing the problem. Its so burnt I can't tell the value. Its right next to a IN5336B diode. A picture would be nice. Please help??
MJE182 is a replacement for the now obsolete D40D8, although the D40D8 is still available on e-bay.

Sounds like the D40D8 transistor the one that stands straight up on the board and not heatsunk! there are two of them. could have a cold solder joint there. have had a few of these problems from people doing hack repairs to them. they look like this http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290297644906&ssPageName=STRK:MEWNX:IT

Channel Master by PCT indoor antennas are designed to provide optimum reception of
UHF / VHF and FM signals. These antennas have 75 ohm outputs, which allow simple,
hassle-free connections to today's newer TV sets that have 75 ohm F type connector
Simply attach one end of the supplied 6' cable with F connectors to the output of the
antenna (Fig.1). Attach the other end of the cable to the input of the TV set or VCR
(Fig. 2). Some adjustment of the antenna might be necessary for optimum viewing.
Model CM-4030 includes a built-in amplifier and separate power supply.
1. Follow the same steps as above for antenna to TV / VCR hookup. Note : Model
CM-4030 also allows for two set / VCR hookups with its unique dual output feature.
2. Insert the power injector into the back of the antenna (Fig. 3). Plug in the power
transformer to the closest electrical outlet (Fig. 4).
