Gents (and Ladies) -
I'm trying to align a very nice Drake 2-BQ and have a few questions: 1- When I switch on the 2B, the 12AX7 in the 2-BQ glows very bright for a second, then quickly fades to two tiny glows. Is this normal? The tube diagram shows two filaments, but not sure about this burst of light at power on. 2- Attempting to do the alignment procedure as provided in the 2B manual; attempting to adjust L2 of the 2BQ to get a peak S-meter reading does nothing - the meter doesn't go up or down. I've gone roughly a turn CW and CCW from the initial position, and nothing. Any comments? 3- Twice this has happened in the past ten hours of operation; after a few hours, with the 2-BQ connected, the 2B seems to lose all sensitivity and audio out. Moving the Preselector doesn't increase output noise, nor does cranking the AF Gain full CW. If I switch off the 2B, unplug the 2-BQ, then switch on the 2B, things return to normal. I have switched out all the tubes; still happened. All in all, both the 2B and 2-BQ seem to work great even with the above concerns. Any help from the experienced would be greatly appreciated. 73 Ferris NB6T
