Thanks Jamie,
I answered most of my question regarding the vertical IC yesterday. TDA8174
and TDA8174A
have two different peak values, and amp ratings. The TDA8174AW is referred to
as a clipwatt
style and is just plastic backing verses the metal backing with screw-hole
mount, thus the
"W" suffix.
As to the resistor I believe I'll try the 20kohm and monitor the heat build-up
on my
vertical IC. With what was left of the burned resistor that I could get to
with my dmm I
guessed at the value around 10k and was going to try that this morning.
Thanks again for the info Jamie!

Bill,
I have a KM1400CN here in my shop. It uses a TDA8174W. I don't know if
there is a difference between the AW & W. But anyway R236 in this monitor is
20k ohms.

> Fellow Techs,
> Need the value of R236 in the vertical circuit on this one. Also, the
vert IC is a TDA8174AW. Is the suffix "AW" critical? Can't find a data
sheet for the "AW"
