Can a Zenith 9-160-030 sub for a 9-160-05?

I have a NICELY working 13" that uses the 030 and a nonworking 19" space phone set that uses the 05. The 05 looks like it has had a hard life....many burned and bridged traces lots of wear, evidence of servicing, etc, and I'd like to confirm it is the problem by substitution with a known good module before I jump in and try to fix it at the component level (assuming there is enough left of the 05 to fix).

Edit - Not according to Zenith. The -04 is the only sub for the -05



CRSP CRSP CRSP - that is the Zenith compatibility manual - remember the title, and the search is easier:

It's the first time I've worked on a SS Zenith.

Thanks, but that manual lists no subs for 9-160-03 (but it does not say to NOT use any specific variant), and 05 crosses to 04.....It is inconclusive. Perhaps I should just hook it in, start my variac at 70V, and hope I get picture and not smoke.

??? Not according to the CRSP - Zenith's definitive word on modules. In the beginning of the System 3 series, Zenith had a high rate of return on modules, and determined that techs weren't following the manual - weren't checking for proper Horiz drive, B+ and so on when swapping modules. The CRSP wasn't in independent service techs hands, so they got a mailing list for shops and mailed each one a CRSP. The result was a drop in module returns (Surprise, that module is not for that set....!) and in a humorous note, some techs wrote Zenith and asked for a subscription to the CRSP. Zenith actually added those independents to a list, and when the CRSP got updated, they got new CRSP manuals.

At one Zenith Seminar in early 84 (I attended with my dad's former boss, A Zenith dealer), they showed a set that was serviced using the wrong module, not sure of the combo, but swapping the wrong module had damaged another module. They also showed off a mod to the ultrasonic remote tester that allowed a tech to check for horizontal drive, a test that allowed you to isolate the fault to the correct module. The ultrasonic remote tester we had already had the IR mod, but I brought back the mod sheet and modded ours - just a resistor and coupling cap - the whole tester was built around an op amp driving an LED to show the pulsing of the remote signal, or with the Horizontal drive mod, the pulsing of the drive signal.

Bottom line is, use the CRSP and avoid the problems. It also lists all the duramodules and some digital modules. I have scanned about 80% and posted in various threads - just search CRSP.

I swapped hundreds of 9-160's
IIRC -03 subs to -05
-04 subs to -06
there was also a -08 ( rare) that subbed back to one of them.
An 05 or an 06 will sub ANY 9-160 between them.

IIRC you can not put the wrong one in due to the
yoke plug without forcing it & busting the skt.

IIRC also the newer subs used a multivibrater to kick
start the set & the old ones a transformer etc.

On some, remotes IIRC there is also a cable that gets
left off on a sub. Plugged on top & had 2 wires. Just
tie it off out of the way.

9-160-05R Was the 25Kv HV Module.

9-160-06R Was the 30Kv HV Module.

9-160-08 or 09 were not available as rebuilt as far as I know.

Does anyone have an older CRSP book I was thinking until the 08 and 09 came out it was odd suffix subbed odd suffix and even suffix subbed even.

The one above:

9-160-05 = 9-160-04

9-160-06 = 9-160-04

Which most likely isn't correct ?

Why would Zenith have made both the 05 and 06 as rebuilt replacements ?

9-160-05 would sub an 9-160-03 but not an 06.

9-160-06 would sub an 9-160-04 but not an 05.

But the 08 and 09 mixed things up a bit.

I think I still have the service seminar for the 9-160 series book somewhere.

Then 2 weeks later the told us not to repair any of them exchange only.

7 CRSP manuals, two from the service caddy, and they all say the same.. The one above is a scan from the blue CRSP, believed to be the last one we used, as the others are stained, dog-eared, and dirty. One doesn't even list the -08 or -09, so probably old. The sequence adds models, no additional information or cross. Our first four or so came as hand-me-downs from a Zenith dealer, and the last few, were included in module orders from Zenith/Bluefield Distributing.

Everyone with "I imagine, IIRC, and I seem to think" - Zenith says otherwise. I have no problems with what others do with their sets - just passing on the facts from Zenith. If someone has contradictory CRSPs, please post for the benefit of all.

Edit: Somewhere I have the PTS Electronics cross reference as well - I'm gonna dig it up and scan that - they may have other info as well...
