National NC-125
#6

Well... today I began testing, and there is good news and bad news. First I tested all the tubes, and I found that the audio output tube was very, very weak, tested bad, but with a tiny bit of life, if you know what I mean. I replaced that. The 0A2 also tested bad, but when installed it delivers the proper 150v regulation, so I am not going to worry about it. The good news is there were no explosions, and everything seems to actually be functioning. The bad news is that somebody has been into this thing and screwed around with the IF transformers. The IF is WAY off, so I am going to have to do a full and careful alignment. It is really pretty though when it is all lit up. I did have to replace the #47 bulb in the S meter, but the other one for the main dial was good.
