I have a 1986 model year Cobra 2000. Final quit working. Just replaced the C1969 final with a used one that I had and works good. My question, I want to adjust the bias. My 2000 service manual mentions a TP3. There is a CRD on the pcb there and a hole but no post for a TP3. This is for the...
thanks for that info. I guess I'll just replace it with at NTE236. I have a Cobra 148 that has a NTE236 final in it and it works fantastic. Do you or does anyone know where I can find a original Mitsubishi C1969 that won't cost me a arm and a leg?
Cobra 2000 C1969 quit working on me tonight. It's bad. I have read that the NTE236 is a direct replacement for the C1969. Is it exactly the same wattage output? What a your opinions on this. Need to order the final soon. Thanks for any info.
that Pace 1000M 23 channel uses crystals. No PLL. The meter doesn't move at all. It's dead just like the trans/receive. Haven't tried trans on LSB or USB but I will next time I hook it up. Doubt it will do anything though.
Just realized I might be using the wrong schematic/board layout I found on CB Tricks. My Pace 1000M only has 2 transformers on the right while the pcb layout is showing 3 of them. Also tank coils are not in the correct orientation. Anyone know were to find the correct schematic/pcb layout for my...
UPDATE, changed out all caps. Still isn't working. I pulled TA7205P and a C106 power transistor. No output on PA and no audio. Relay is clicking when mic is keyed. Still no trans or receive or PA also. I have the 2 parts on order.
thanks I did use detoxit on the channel selector but that didn't do anything. I will look into some more soon. Would really like to get this thing going. Thanks.
I have a really clean Pace Sidetalk 1000m I hate to throw this radio out in the trash or use it for parts if it's a simple fix the issue with the radio is it does not fully power up. There is no light on AM USB or LSB lamps also the channel selector lamp and meter light are not working. The RX...
This 101B almost got tossed out in the trash last week. My friend called and asked me if I wanted it. His father recently passed. Don't know much about it. I have a lot of CB radio experience. Going to clean this thing up and fire it up soon.
no one has been in the radio. Transmit is dead. I have tried everything. Replaced all electrolytic caps, tested some of the C945 transistors and a few diodes. No luck. Yeah I'm listening in on another radio when keying the mic. Nothing heard. Red/Green LED's do work. PA works, talkback works...
I have a 2007 model 29 LTD Chrome that's in great shape, but it will not transmit. I have checked the driver and final and a few of the 2SC945 transistors and all have tested good. Also recapped almost all the electrolytics. The PA and talkback have audio so I don't think the audio IC is at...
I have a few TOKO RCL coils I need to test. Really just need to test the coils for a open/closed coil. If it's good or not. I saw on ebay that here are a couple of different low priced LCR meters that can test inductance. Anyone ever used one of these to test these toko coils? Thanks for any input.
