Hi
This looks like a sensible news group! who but sensible people
would want to repair and play with Old Knackered Radios )
Being a lonely Brit trying to refurbish an old American Radio
I'm a bit stuck, I have repaired the old girl and it works very
well after sitting in a garage for many years as a home for
spiders, But I can't seem to align it correctly in as much as
I can't get the osc to track the dial reading and keep it in
good spec across the band? also I'm a bit worried about the
bandspread dial, it reads 100 with the tuning cap fully in
this means as you go up from 0 to 100 you are going down in
frequency? is this right? or has someone strung the dial cord
incorrectly? do I align it with the bandspead cap fully meshed
or not? I could really do with the alignment instructions has
anyone got them out there? I've looked for a manual but they
either want lots of $ (whatever they are ) or the ones that
are available don't have the circuit or alignment details (
Also Are there any transfers or refurb material available
I'd love to respray it but don't want to lose the original
transfers or logo, any help very welcome

I recently aligned my S-77 using the instruction from the BAMA site. Not
hard at all.

Keep in mind, very important - make sure that the first thing you check is
the range of the tuning dial. If this is off (mine was) it can cause all
kinds of trouble. There are index marks at each end to set it's travel.

I was able to get all bands quite close except for the high one. It tracks
fine at low end, but above 30 MHz it's off. I messed with it awhile and let
well enough alone. Who listens above 30 MHz anyway? I set it to track
correctly on 19 and 16 meters.
