Well, I found that the Hong Kong models are better RF performers than the
Malaysian ones. I don't know any more though.

A while back I read some information about the various versions of the
GE SRII...the differnet letter suffixes, and theh date codes and seial
number ranges, plus where the varouis versions were made and which
were supposedly the best.

I can't find that info now...does anyone know where that info is or
can they pass it along?

Thanks,

All the SRI/II radios are equally capable. The difference is the care taken
with pre-market alignment. I've found some out of the box that could be
bettered by at least 6dB by a simple RF/IF alignment. Problem is, as with
most radios starting in the mid 1970's, that 'alignment' on the assembly
line amounted to setting the RF/IF transformers and trimmer caps to the same
physical position. Good practice in theory, not so good in practice.- Hide quoted text -

My experience indicates this is not quite true. I generally align all
my old radios and I have found differences in them after they are
aligned. You are right though in that some improve much more than
others but this is for a variety of reasons. My general experience is
that some have a diferent apparent AGC curve and some have a large
difference in tweeter level.. On some the AGC action on weaker signals
ia less which means weaker signals, although received about as well as
on the other samples, come in at lower volume, and when you increase
the volume to compensate you lose some of the loudness compensation
which makes them sound thinner. I don't know though if this is a unit
to unit of version to version difference as I have only algined a
handful fo these..perhaps 5 or 6. The tweeter level difference is
clearly audible on AM or FM althugh it can somewhat be compensated for
with the treble control.
