Zenith SMS1935S

[gilloz]

Does anyone have a schematic drawing of a Zenith 20" TV model
SMS1935S? I am looking for the schematic of only the audio section.
I am confused by the part numbers stamped on the two transistors in
that section. They have the same part number, but each one checks out
as an NPN and a PNP. Schematic would sure help.

Q800 121-975A NPN
Q801 121-1300A NPN
Q802 121-1301A PNP

Audio enters Q800 from Pin 1 of ICX 1200. Audio exits Q800 at
collector to Q801 and Q802.
B+ for audio circuit is supplied at RX809 of 13V.

Hello David:

Thank you so much. Seems everywhere I checked, this schematic has
been discontinued. Your information is very much appreciated. Thanks
again. Gil
