[TenTec] T-T 509 band edge alignment ?

[n4elm at tx.rr.com]

Anyone ever have to align the band edges on a Ten-Tec 509?

On the newest project radio, a 509, I have finished re-greasing the PTO which works smooth now but the radio must have set up a long time cause the grease was just a sticky residue which required WD-40 and pliers to loosen the shaft enough to disassemble it.

Anyway, now that it tunes, a check of the lower band edges shows a 20 - 30 KHz difference from band to band with 40 Meters being off by the 30 and the others closer at ~ 10 KHz or so. The manual mentions adjusting the band inductors for band edge and band tuning width but does not mention which inductor controls which function.

Yea, I can just try tweaking one and see where it goes but I was hoping someone has done this before and can start me off in the right direction.
