A couple of weeks ago I managed to acquire a Hallicrafters SR-2000 with the P-2000 power supply for a really good deal. After a full recap of all the electrolytics in the power supply and cleaning of 50 years of oxidation on contacts, dirt and general grime, and replacement of one bad 7059 tube, the radio was brought to life. At this point it is receiving very well on all bands that have had activity. Due to this past weekends contest I was able to hear a ton on 15, 20, 40 and 80 and I must say I am impressed with the receive on this guy. Here is where I need some assistance... 1) Power supply makes a horrible buzzing when the HV is engaged. Good news is that the HV does engage and I get 1700 V but the buzzing makes the windows shake. Assuming its a choke issue in the power supply but how do I diagnose which one and what are my options for the one that turns out to be bad. 2) During my investigation while I was cleaning this radio up and getting it ready to go, I saw that some previous person had removed the cap connections from the 8122 tubes. Interesting I thought. Had no idea why they did it so I reconnected them. When I follow the tune-up process from the manual to the letter as soon as I switch over to "MOX", the HV instantly switches off. So, were the caps disconnected because the 8122's were NG, were they disconnected because something else in FUBAR in the transmit section? Where do I begin troubleshooting this and is there a source for matched 8122's should mine be NG. I have no way to test the 8122's 3) S meter/screen ma meter is not working. When powered on the needle goes to about the "5" and sits there. On a really strong signal it will move very slightly. Also If i change the switch to Screen MA it will peg the needle below zero and it won't come back up till I power off and turn back on. Where do I begin on this one? I will post some videos and pictures soon.
