CG left channel out

Post: # 22932Post Hydrolastic »

Hello Guys. So turned on the 60 CG and the left channel has gone quiet. Couple of things to note. I unplugged the rca input plug from the right amp and there was no noise on the left side.(no hiss ,clicking, or static ) I also swapped L and R leads from my bluetooth adapter and both channels worked. Both amps are lit up on the tubes. Where to start ? Hydro

Hydro, are you saying by swapping leads on your Bluetooth adaptor the CG worked on both channels or the Bluetooth adaptor was working? Have you tried playing the radio and record player to see if either of them plays through all channels?

Are both amps on the left channel quiet? First suspect is always a switch. Function switch, external speaker switch. Next suspect is a Molex plug/connector. That is a chronic problem with Magnavox bi-amps as they age. My CG isn't so bad, but every time I run the Imperial, it seems like something isn't working, usually the treble amp on Channel 1.

Hello guys, Sorry for the late reply. I have been madly trying to get a house project done as my wife is out of town. I think you may have it nailed the molex plug, This is the strange one we talked about and I don't think it is connecting correctly. Will look at it closer.

Hello Guys, Update: I was heading to LA to deliver some car parts to a friend. I realized that Steve at Midcentury sound was near riverside (3 hrs away) So I contacted him about going through my CG. After owning the CG for a couple of years now it was frustrating that it was dying. first the lights went out then the magic eye stopped working and there were other issues with incorrect connectors and finally the left channel went out. I messed with the connector for hours and nothing. I have come to the conclusion this is not the console to learn on especially with so many issues. The adventure began. I disassembled the CG being methodical in labeling every fastener and found more issues. Anyways I had to get boxes and packing material. Since these were going to be shipped back to me. This took a day and a half to do.
I then went to LA and spent a few days there then on a Monday morning I took off to I-15 got a half hour into the drive to the Cahon pass and stopped and I mean dead stopped like get out of your vehicle and stretch your legs. Get in start it and move 40 ft and stop again. 5 hrs like this. The freeway was closed apparently. Something about a crime scene with a shooter and a casualty. Finally got moving again. It was a pretty good pass I had to slow down to keep the truck from overheating. IDK how hot it was but it was very hot outside. I arrived in late afternoon. Steve was understanding about the delay. We talked about what needed to be done and I brought a spare MPX unit to pirate the connectors from and the rest of the bits like the wiring with the selector switch so he could make it all work again. I suspect its going to need a lot but we will see. I may go down to get it after Christmas if its done. So that's the update ! Hydro

Thanks for sharing, Hydro, and it sounds like you had quite the adventure. I hope Steve can make it like new without breaking the bank. Good luck and please keep us posted as things progress.

Steve will get you fixed up! Riverside? He was in Henderson, NV last I saw...maybe it's a 3 hour drive between the two...

As soon as I get twiddling with bakelite radio cabinets out of my system, I'd like to dig into my CG again. It will be interesting to me to see what Steve does to Hydro's CG and how it turns out. Please keep us informed, Hydro.... ;) ;)
