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...

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...

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...

Hi all, I am working on a texas star 667v and am having trouble, I am getting 2 ohms from the bases to ground not 1.3 to 1.5. I have replaced all 3 of the half watt resistors though I had issues with them 2.7 coming out and reading at about 3.3 ohms, I even took 5 - 10 ohms and twisted them...

Hi all I have a few questions concerning a Ranger 69ffb4 one of those old chrome faced models with the hard to read red print. Seems to me this radio should do a little bit more then I am getting out of it as it's doing right around 275 pep on a dosy and I have seen these radios do much more...

Hello all ! I was recently given this sweet sixteen that needs alot of help ! My skills and or knowledge with the pill amplifiers lacks a bit so I am going to need a little assistance here. When I recieved this the transistors were already removed so I do not know for sure what version it is or...

Hi all, was wondering if anyone would happen to know what amplifier this might happen to be as I don't believe I have ever seen one before, appears to be 2- 6LQ6 driving 5-24LQ6 configuration. Has a date on the inside of the unit as 1972 . Thanks

Hello, I am working on a kenrich eagle 200 that a buddy gave me that needs some help, the only schematic that I have from a member on here I believe is fairly blurry and I was wondering if anyone could tell me the value of the resistor at R11 ? Also possibly if there is a diode at D9 ? Is it...

Hi, I am kinda just getting started working on radios of this sort anyways and I have a RCI 2970N2 board model EPT695015BR the radio has hardly any output wattage at all but I can hear it on another radio close by, the things I notice that might be a hint to what's probably wrong with it is that...

Hi I have a Browning mark 3 reciever that is not acting correctly and wondered if anyone has run into the issues I am having, so far I have cleaned the relay in the transmitter and tested all the tubes and they all tested good ! The issue is the meter is peaked and never drops down when it warms...

Hi, got a new to me Eagle VIII that is leaving me with much to be desired as it is only putting out a pep of 600w max I am pretty sure it ought to be doing quit a bit more than that as I have some that have less 20LF6 tubes that blow this one away ! So somthing is wrong with this one, looks...

Hi there, I have this modulator that is alot like a JB12 that I am working on and recapping after opening the unit up I noticed that there is a pair of old camera batteries 22 1/2 volt that are being used for the negative bias LOL, I also noticed there is only 4 wires coming from the transformer...

Hi guys I am wanting to replace a golden eagle 750 keying relay. This is the black box linear. The relay has part number ITT 4ZB-CR or possibly 35577. I have been unable to locate one with this part number and the other thing that is confusing me is it says it's 24 VAC ‍♂️ ? When I test the...

Hi all, I have a Dentron 2500b that I can key up just fine with a pedel but it's rf sniffer circuit or whatever is not functional and this beast is a little different than what I am use to working on. I guess my question is what do you guys think could be the issue since I don't see a keying...

Hi guys I am about ready to pull my hair out over this modulator, last week it hot plated a tube popped a fuse so I went ahead and replaced the HV capacitors and the 100 uf 200vdc capacitor for the bias. When it first screwed up I put a voltmeter on pin 5 on the 8417 tube and watched the...

Hi guys I am a little confused on this old carbon resistor here, what exactly is the rule of thumb here, which is the first band ? The red ? If calculated like that this would be a 2.23 ohm resistor however it is reading 23.75 K ohms. If calculated the other direction it should be a 24K ohm...

Hi all, I have a Siltronix LA-650 here in need of a plate tune air variable capacitor part # 074-064 and am having issues finding one, anyone know the specs on it or one that would work fine in it's place ? Thanks

Hi, I recently got ahold of a Maco 750 that is in need of great help as it has several issues I am aware of, one of them is, there is a white wire coming from the large capacitors that is carrying 450 VDC that had come off from wherever it is supposed to go ? anyone know off hand? It goes...

Hello, I was wondering if you guys could help me identify these components and or inform me on what type they are ? Resistor, diode, and capacitor perhaps ? But not sure of their types, values or what to call them to order or find them. Thanks

Hi everyone, I recently got a used RCI 69ffb4 and I was wondering what the output on just the radio itself should be without the 4 pill on, anyone happen to know ? Thanks
