Over the years bypasses went from .1 to .01 as both technology and knowledge improved. I have no problem using a .05 in place of a .1 or a .01 in place of a .05 or anything in between in sets that cover the BCB to say 30MHz and use 450-500KHz IF's
When the tuning range goes well below the BCB and/or much lower IF's are used I stay closer to the original values and do a quick capacitave reactance calculation first.
Hammarlund had a thing about using .02uF over about two decades, however Id have no problem using .01 if thats all I had available and didnt want to wait. Their design changed very little over that time also
The 129X is also very prone to way out of tolerance resistors and dont forget to pull off the BFO coil cover for caps and resistors.
