All = bands are working ok. Band 6 had a problem related to L6, the antenna = coil for the band. It was traced to the development of a cold solder = junction in a connection to the coil. All the resistors were found = inside their tolerance values. Corrosion inside the tuning oscillator, = mixer box was not much considering the fact that a denisen related to = the rodent family used to live here for a while. Cleaning that area was = quite some work. Luckily no corrosion affected the capacitor plates. = Lubrication did wonders to finally attain a very smooth tuning capacitor = movement. All tubes were checked and only a 6BA6 was found to be = marginal, another one was suspicios so both were replaced. In the 12AX7 = socket I found a 5965 tube that is supposed to be the industrial = alternative to the 12AU7. I replaced it with the correct tube. That = action seems to have eliminated the pegging of the meter to the left = under no signal conditions. There is a 25uF electrolytic as a cathode = bypass in the 6V6 circuit. The manual indicates that it is a 500VDC cap = but I think that this is typo. It is probably a 50VDC cap. I have been = giving it quite a run during the week to see if anything else pops up. = Now I will prepare the old original transformer for shipping and = rewinding. This set should be all original. In the meantime I will keep = operating it with the replacement. In my opinion this GPR 90 compares well with the high end Hammarlunds = like the HQ180. It requires about 30 minutes for stabilization but after = that it remains right on the dot. Sensitivity and selectivity are = excellent and the audio filter works as it should. I also found the = crystal calibrator right on frequency by tuning to WWV. Cosmetically the front panel is OK and some mild polishing will do = wonders for it. I already tested in a corner. The blue-gray panel where = the meter is mounted was removed, cleaned, prepared and repainted. I = found that Harris Paint universal gray engine enamel closely matches the = original color. Now, work on the really dirty cabinet commences.
