This is what I need to do as I have a like brand new B&K scope in the box that a friend hooked me up with, and I have never used a scope before, but its about time ! I also have a coax tap for it that I have never used also

I have noticed the signal in on pin 2 stays at 1.976 v and does not change with the channel selector

Yes, think I will be doing this the way you and tram d recommend, I ordered the sockets. I am not positive it is the chip that is bad but there is no change on the outputs of this chip compared to the other one, it did not do the same thing

Thank you Dr. Frankenstein but you know alot more about this then I actually do I can tell. One thing though as far as the schematic goes I know there were 2 different cp 2000 boards the older one and a newer one and I have the newer one and I am thinking the schematic was for the older one as I...

That was a picture of them before the replacement Nomad here is what went in

Also, all I have on the front of my amplifier is what's on this photo, other models were different I think, the one you worked on might have have 4 knobs

I know one thing Bayyouradio, when I got this unit all 4 diodes closest to the driver board were all blown so I replaced all 8 with 5408 diodes and figured then I had already found my problem, WRONG unfortunately

Or transformer I really mean

Probably but hopefully not in my PS

I have seen this same style 10 watt 2 ohm resistor on other people's JB2000 running off the 3 amp fuse holder going to the HV capacitor board, however there are several different models of JB2000 as we know. There are not any burnt traces on my HV board as I have already rebuilt it, and replaced...

I ordered about 4 of them since I have heard they run hot anyways, the shipping was more than the chip itself so might as well get extras

mine just had the solid core wires and that was it, is it a good idea to install the 10 watt 2 ohm resistor because if so I already have them, thanks

Mine did not originally have that resistor, I had bought some thinking i would put it there but haven't yet ! You mean the one that would have been coming off the 3 amp fuse terminal to the HV capacitor board correct?

These here would work wouldn't they TM86?

Driver board

She now seems to sit content all day as long as there is no plate voltage on the tubes now, but didn't necessarily seem like it before as it sounded like the amp would try to kick out the breaker even without the tubes installed. Rf choke, parasitic, and power supply have not been replaced

Wire was like this and I have removed it

Hi, I did try a couple caps in the vacant locations and it did not seem to make any difference at all. I do know that there is not any voltage changes on the outputs of the chip that I have the red pointer on when changing the channels, should there be ? I am guessing so. When I got this radio...

I have been back to messing with this thing after leaving it on the bench for quite some time over the summer. If I can figure out what is going on with it I will probably continue with the driver bypass but would at least like to see it functional first. It was my understanding that running the...
