Well, tonight I replaced the 4 electrolytics that remained in the Space Command and also a 27K 2w resistor to still see no improvement. I thought for sure the thing would come to life or at least some major change in performance. To those who dont know I am working with a model C4007R with 18C24Q chassis. I am about stumped with the exception of wondering if some kind of short in the remote control chassis could cause this set to have almost no vertical sweep and volume adjustable hum in the sound. The power lead to the remote unit has to be plugged in to fire up the set. The only other thing I have questioned is the use of a 5u4 in the place of a 5au4 but everyone seems fairly certain that the swap is OK since the set is producing B+. If the remote is part of the circuitry I guess it would be logical to think that it could cause some kind of problem but I would think not in 2 or 3 different sections. Although I have bragged on how unused this set looked when I bought it I will say I did find evidence of some repair in the form of 2 .1 600v redish versions of orange drops. Maybe I am the victim of someone elses botched repair attempt and some cap is hooked up wrong. One of them is in the vertical section. This set has some strange and uncommon problem I think. I would love to figure out what it is. If that remote unit were the problem the whole time I will be pissed but happy if that makes sense.....
