Thanks Leroy for clearing the part #'s up.
I was just quoting from memory. It's hell to get old.

[Correction]
Steve,
If you need to replace IC3401, be sure you use Zenith part # 221-291
which crosses to an NTE7002. The 221-466 crosses to a NTE7096, and is
the wrong part for your module # 9-323-04. I know you want to try
replacing the opto-Isolator IC3402 first,...and we have the correct part
number for that one, which is 162-18 (NTE3041).
I just wanted to clear up any confusion on this subject.
Regards,
LLW

Steve,
I can confirm that the part numbers Max has provided, are good numbers.
Opto-Isolator is IC3402 Zenith part # 162-18, and IC3401 Reg. IC is part
number 221-291 (the 221-466 might be an updated part number, or a kit
number that includes the clip, and heatsink, but the original IC itself
is 221-291 on the micro-fitche parts list ).

=A0=A0Steve I don't have that schematic but I recall thos Zeniths used
ICX3401 part # 221-466 (NTE 7096) and ICX3402 part # 162-18 (NTE 3041).
I have them both and you can have them because I don't need them. If you
want them send me an address.

Any ID on the Opto Coupler? Is it a 4 Pin Dip Like the NEC PS2501 ?

Steve,
Only tips I can find, are: Check C3416 (100@200), and replace IC3402
(opto-isolator).

Cannot Find a SAMS on this one. Circa 1986 Set. Need Values of R3424 and
R3425. If anyone Has a Diagram or a Scan Let me know. I did not check
our Archives yet because I think the Set is too old. Will Check Leter
just to be sure. Set Not Powering Up - Found Some Tips on Some BAd Caps,
but if anyone Has worked on this Chassis, I'd Appreciate a Chat With
them.
