[TenTec] Subject: looking for a schematic

[Dads Desk]

Bob, I have a schematic here that probably matches the one you have. 
Looking in the drawing here is what I found. The U1 is supposed to be a 
TL442CN, but the board actually has a MC1496P. I think the drawing was 
done before they came by the MC1496P. This is not out of the ordinary 
for Ten Tec. My suggestion is, I would be very careful that the DATA 
SHEETS are for the correct chip, and then go from there. If they are the 
right sheets then check the wiring. Maybe some one has a different book 
for a Corsair I. That might be where the confusion came in. Anyway, I'll 
get the pages copied and attache them to a email to you. 73 Paul K. WA0BAG

Hi All,
I am in the midst of restoring my Corsair II (a bucket list radio) and
discover that the board doesn't match the published schematics or
manuals. Specifically my board has the Motorola MC1496 IC and the
schematics all have the TL422. Pinouts are totally different. While this
is not a showstopper, and I am sure I can figure it out by using the two
different datasheets, I can't help but wonder if there are other
"gotchas" lurking on this board that I might miss.
By any chance does anyone have a schematic they would be willing to
share, either electronic format (preferred) or paper? This is for the
80975 Oscillator Mixer board.

Thanks in advance and VY 73,

Bob W1ICW
