[fields 100]

That little thing gives me plenty of headache. After fixing the 6A8 tube (all contacts inside the base were loose, go figure),
alignment was an order of things. The set is very sensitive and receives many stations but all over the place with at least 20K.C. discrepancy, and that discrepancy is not linear.1500 is at 1200, 800 is at630, etc. The alignment procedure is written very laconically. So, first to k work with are 2 IF tr-rs, then the wave trap,after that 3 other trimmers, that takes care of BC alignment.All has been done,but even after that the same problem still persists.The only thing damaged in this set was the osc. coil, which I rewound with exact amount of turns observing correct rotation.The only difference- slightly thicker wire gauge.Did not touch any micas. One issue I had was the trimmer J - I was running out of capacity to the point that I almost cracked the porcelain base of it.It is about 390PF max. So, I added in parallel 40PF with no positive results.
Any ideas? Thanks.
