This is the newer version of board also and I think the schematic is the older one if that helps

Can anyone tell me or show me on the schematic what value of caps I should put in each spot, my eyes are having trouble tonight to see the small schematics lol

There is also a couple xtal pin isolator rings on a couple of the transistors there, not sure if they did that at the factory so the pins don't make contact or what.

Ok, here are my findings guys. I do have -8 bias on pins 24, 14, and 17. But I did discover this with my magnifier and I looks like it is missing a couple disc capacitors ! One of the photos here with the missing caps is my unit and the other is. Screen shot from another radio. Look where the...

10-4 on that Nomad I did not know that, I do now

Absolutely awesome TM 86 thank you very much for that as now I understand it a little bit more now, I will check for the -8 on those pins at the end of your post ! I did find -8 on one of the test points on one of the boards but it wasn't on this chip. Thanks I will get back with the results

I do know that there is change on the pins of that chip as I change the channel selector it will go from like - millivolts to positive voltage usually in the +3 to 4vdc range

I am very new to this kind off pll work but if someone can assist on exactly how to checkit I am sure I can get it done

Could you possibly go into a little more detail on this as I am new to pll eprom, what type of change am I looking for on the MM 5221 ? Any help would be greatly appreciated

Hi I recently acquired a CP 2000 that is in need of repair. The radio has no output power and hardly any recieve at all and was wondering on where I should start on this unit. It looks untouched inside and pretty clean. I hear clear audio on PA but that's about it, last night I heard faint...

Yeah, I tend to not move them either Nomad, especially on Texas star boxes. Thank you

The new pot came in and I installed it, the amplifier appears to be working good

There is readings off of it but mostly in k ohms

RV4NAYSD251A is what was on the back of the control, I guess this is supposed to be a 250 ohm pot but when I put the multimeter on it read pretty crazy and there is a bad burnt spot on it so I ordered a new one and hope for the best I guess. I will try to get some photos of it on here soon. I...

Hi all I have this Golden Eagle 300 that I would like to replace the variable potentiometer on, I feel the one that is in the amplifier feels gritty when turned all the way up and am pretty sure it has been replaced before and am not even sure it is a suitable one. I haven't been able to find a...

Yeah, Nomad I toltally understand what you are saying here ! I would be very interested in the bypass conversion instructions if you could locate it . I am also planning on installing a fan for my new tube sockets also as I have read about the solder pins issues. I also wonder and am interested...

Also I may add that mine does not have the 10 watt 2 ohm resistor off of the 3 amp fuse holder to the HV capacitors either but think I will install one. Also, what is this 25 watt resistor I have circled, don't believe I have seen that in there ?

Hi all, I recently got ahold of this old JB 2000 and I am attempting to get er going and am having issues with it. Things I have replaced on it so far are HV caps, 3-500z tube sockets, and all the rectifier diodes. When I replaced the diodes all 4 on the side my finger is pointed at were all...

Yes sir ! Running it with a ol Phillipines 148 with a swing kit on it
