It was Bill. " LET ME SHOW YOU SOMTHIN" ! LOL

Yeah, 10-4 on all this Nomad. Could be still somewhat gassy tube i spose, but they are new tubes but possibly NOS so who knows how long they sat around, they were arching at first on power up on standby! They no longer due that though after I cooked them in slowly for 2 weeks. The tube sockets...

This thing is still operating but I now know why they named it the blackcat because it sure sounds like one every half hour or so !!!! Just like the firecracker, it doesn't pop the breaker on the rear since I have replaced it and doesn't pop the 3 amp HV fuse either but boy it cracks, scared the...

Yes, sir I did add a small AC fan down there in that location already as I have heard and read about the pins solder getting to hot at times. I did not add any bias or any input tune at this time but am very interested in it if it will make this box run better and or more efficient. My input swr...

Yes I believe so, and not sure why

I do now currently have this amplifier operating, I am not for sure what I did to get it functional I do not know if the tubes were gassy and that's why it was arching in them before or not. I burned them in for like a week with just the heaters on first, then added 1300 Volts to the plate and...

Got a new toy for Christmas and yes pin 2 looks real close to 4 MHz

Yeah, I see that too ! Yeah pin 11 of the pll is clearly not going all the way to pin 3 of the divider but it shows it in the schematic? Hmmm anyone else know anything about that ?

I now can get some signals off of it but I am at .5 micro seconds on the sweep time/ div this is pin 11 on the ic I replaced

Hi, Thanks for your reply, I have adjusted just about everything on this scope when it comes to getting a waveform from the radio and all I get is a blotch of green, I have messed with the sweep time / div and volts div with no success, I did get the probes calibrated I believe. Here are photos...

Hi Nomad thanks for the reply, I think you were correct about the age of the scope though and I do not think it is operating properly. I did take the cover off today and cleaned the volts/ div as well as I could and it did help, I went to calibrate the probe and you can barely see the vertical...

Yeah, I am new to using a scope and I need to work with it a bit and do some research in them, I will try your adjustments and also look into how to calibrate the probes because no I did not calibrate them yet. Thank you for the advice I appreciate it, this is a new ordeal for me

Where as the other 74160 ic outputs give somthing that looks more like this

I do see another thing, the 74160 ic on the far right there just gives this on the outputs

Like I have said I really don't know what I am doing with the scope yet for sure, but Nomad helped quite a bit here, I turned down sweep time/ div to 2 and put the probe on pin 2 on that ic I had replaced and the line rises but I really don't think it really shows a waveform I don't know. The...
