Phil, your message is in the archive but hasn't filtered thru MSN yet, this
set does not use the SBX module it is about 5 years too early for that (1988
vs 1992-94). It has the tuner, PLL and MTS module (one that uses DIP IC and
standard caps) all grouped togther on the left (As seen from the rear),
Chassis uses a STR3035 reguator, It is some waht the poor earlier cousin to
the TS20, it is of the series just before switch mode power supplies were
used in the sets. (series prior to the LN-1 ie kv27ts27). PLL and tuner were
resoldered, Yoke was replaced as it would wine while cold.

Sony
KV27TS11 (this is a 1988 model, sony's low end stereo but no AV)
Set has audio reception problems. On antena it is fairly ok
exept in cases where signal canacelation/ghosting is just right audio get
mute and tinny. At the customers house running on cable (either system is
comcast and is either standard cable or IRC I not sure which) Audio is
almost not existant and is mostly just hiss (Pink noise) on channels higher
than 6 ( VHF-H and cable). On antena CH 6 audio is picking up an ajoining
radio station (88.7 FM) Although replacing the AC Bypass cap on the input
with a .33 (up from .22) signifcantly reduces this. I wa looking for the
sound IF but can't find any sound labeled coil...
