I am aligning a 650 and have the osc tracking nicely (adjust the trimmer in the can at 1600 and the outboard trimmer under the chassis for 610)
The RF does not track well in my observation. I can peak it at the high end or the low end and seems to be very sensitive. I could "optimize" it ,but it would be a shame to waste the gain for poor but even performance accros the band.
Am I expecting too much or should I look further.
Current conditions:
Total Re-cap
Out of tollerence resistors replaced
Tubes "tested" good
Using a 10' antenna for testing.
Blocks rebuilt
Looking for a clue,
