Default Help with Hallicrafters S-77

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've never worked on this particular radio, but I believe it's similiar to
the S-40A, which I have.
The bandspread cap must be fully open to align the radio. The bandspread
dial might read "Set to zero for normal tuning". If so, it should be at
zero with the bandspread cap fully opened. Both knobs should close it's
respective tuning capacitor (lower frequency) when rotated counterclockwise.
I mention that because the dial stringing diagram is incorrect on my service
manual. The oscillator frequency is above the signal frequency on bands 1 -
3 and below it on band 4.

The BoatAnchor Manual Archive has the service manual online:

So, how hot does that ballast resistor get?

Hi Frank thanks for the info, I wish Bama did have the manual
but when I download what they say is the manual all I get
is a couple of pages on replacing the ballast resister (

The S-77 is described as the AC/DC version of the S-40B. The power supplies
are the major differences, the alignment instructions should be the same.
So, try downloading the S-40B manual, or any of the others from the S-40
series.

Ron:

It's up there, all right, but it's in some whacky .djvu format, which
some other docs up there are in as well; you need the right plug-in to
make MSIE work with it, and MSIE, I think, is the only way you're
going to be able to view it. It won't allow you to export the doc
either, except as individual .BMP files. (Everyone always has to have
a new format...sigh. Too bad they just couldn't stick with the
standard .PDF file format...)

I usually run Mozilla, and the plug-in just will not work with it at
all; if you are running Netscape you might have problems too, as the
rendering engine on Mozilla and Netscape are the same.

I'll try and get it into a .PDF format; if I'm successful, I'll let
you know. I may have to dump every page into a bitmap, and imprt that
into Acrobat, which is pretty much the leading recognized electronic
document format.
