Problem solved! Turned D19 in secondary menu to "on' and all bands are now within the spec'd VCO range. My thanks to Don, W3FPR, for suggesting this!!

K2 #5266 aligned beautifully after I fixed C-6 which the Cheap 'N Dirty Signal Tracer found in about 2" flat. I had it on the air and made about 100 cw contacts before adding some mods: DSP, SSB, NB, 160 meters and 60 meters. I had a problem which was resolved but involved a master reset...so I started on a complete re-alignment today.
With the exception of the 40 meter band, the VCO alignment went "by the book" - 7000 and 7300 Mhz both read 7.92 volts and it does not vary as I tune between those frequencies. I have checked the parts which were replaced in adding the mods noted above and re-heated C-71 through 75 and D-19 & 20. Hooked it up for testing and it's still a rock solid 7.92 volts on 7000 through 7300.
L-30 is the correct inductor; T5 (wound by Mychael) and D21-26 all worked the first time around on the VCO alignment so I doubt there's a problem there.
Does anyone on the reflector have any idea where I should look next? If so, I 'd appreciate it!
