GE SR II Versions
 

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,

Jay

My SR I was made in Hong Kong and the SR II is made in Malaysia.

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.

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.

Have a link to your alignment procedure?? Equipment??

The SR alignment is typical. For AM alignment you can do it with an RF
Signal generator and a VTVM. If your generator is not terribly
accurate you can use a digital world band radio as a reference to get
the frequencies exact.You first adjsut the 4 IF's to 455 KHz, then
align the oscillator at the top end of the dial for 1630 KHz, the
bottom end for 510 KHz, followed by antenna and RF peaking adjsutments
at 1400 KHZ and 580 KHz.

He http://groups.yahoo.com/group/SuperadioIII/ Go join that-the SRII
manual is in the files section. I put it there.
