Okay when troubleshooting you must resolve things that defy logic one by one until the mysteries are all gone.John1397 said:I drew up three different speaker hookups and voltages around output transistor.
I found this online a genuine delco book that drawing is right . I measured 0.8 ohms across this . On one side of this device on the circuit board it says fuse and the other side it says res. It is kindy 3/35" diameter 3/8" long looks like in metal can has cotton sleeve over the outside. I thought it was a thermal type fuse to protect the output transistor.jim hardy said:Is there something missing from your three sketches ?
View attachment 231732
does that say ".47 fuse" ?
Where'd you get that drawing ?
John1397 said:I seen online some one wrote when changing geranium to silicon double resistor value from base to collector. Mine is 22k so if I change to 44k should work?
Can't argue with success, can you ? Must feel great to hear it playing .John1397 said:I finally decided to inject audio signal at volume control to see if amp part works rather than fixing every thing and it did so I then connect signal from radio and it worked.
Got a Picture ?John1397 said:Found the on off problem anyone fixing these watch for tab punched out of top cover so it doesn't touch circuit board and short out signal. The tab bent down on cover about 1/4" should go on part of circuit board with no foil.
There are a few signs that may indicate your 1965 GM car radio needs to be fixed. These include no sound coming from the radio, static or distorted sound, or the radio not turning on at all. If you are experiencing any of these issues, it is likely that your radio needs to be fixed.
It is possible to fix your 1965 GM car radio yourself, but it may require some technical knowledge and tools. If you are not familiar with car radios or electronics, it is best to seek professional help to avoid causing further damage.
The time it takes to fix a 1965 GM car radio can vary depending on the issue and the expertise of the person fixing it. In some cases, it may only take a few hours, while more complex issues may take longer. It is best to consult with a professional for an estimate of the repair time.
The cost of fixing a 1965 GM car radio can vary depending on the issue and the repair shop. On average, it can cost anywhere from $50 to $200. Again, it is best to consult with a professional for an accurate estimate.
Yes, there are a few troubleshooting tips you can try before taking your 1965 GM car radio to a repair shop. These include checking the fuse, making sure the antenna is properly connected, and cleaning the contacts on the radio. If these do not solve the issue, it is best to seek professional help.
