Hi all,
Let me begin in the beginning.

I bought a Philco 89 cathedral, early style, 3 knob, 89 escutcheon, with a cabinet tag of the 89/19 model.

Chassis looks just like an 89, BUT... it has a Philco chassis decal stating
its a Philco model 71 Code 125..

OK.... I've found no listing for a code 125 in a Philco 71 and this is definitely and 89 chassis....

Whats up with this?

Thanks

Keith

Hi Keith, and welcome.

Someone on the assembly line at Philco goofed, and put a Chassis 71 decal on an 89 chassis.

This is not the first time I've heard of this happening. Someone once e-mailed me photos of what was obviously a Model 91 chassis, yet it had a "CHASSIS TYPE 19 CODE 121" decal on it!

Someone wasn't paying really close attention in early 1933...

I'm pretty sure there WAS a Chassis 71 Code 125. I'll have to look it up though. 71 Code 125 was probably a model with the three cylindrical tube shields replacing the large hood-type shield on the left side of the chassis (as viewed from rear), and with a shadowmeter.

(edit) By the way, Keith, I saw your photo of the decal in the binaries newsgroup, but not your photo of the chassis itself.

[Keith Park]

Thanks Ron,

Yea... I thought maybe a goofed decal but when I hadnt heard of a 71 code 125 before the mystery deepened. The power transformer was dated 12/32

The picture of the chassis itself is just below the decal pix on the binaries group... just page down.

Thanks,

Keith

[Ron Ramirez]

Okay Keith, I went back and this time I saw both pictures. Yes, that is most definitely a Model 89 chassis.

For the benefit of those here who do not have Usenet access, here are the pictures in question. Keith, I hope you don't mind my posting these here for Phorum members to see.

Ahh... you can post pictures, great! yea thats fine...
This is a good working little set!

Thanks,

Thank YOU, Keith.

DIFFERENCES BETWEEN MODEL 71 SETS

Code 121 - Tunes 550-1500 kc, single speaker
Code 221 - 550-1500 kc, twin speakers

Code 123 - Tunes 520-1500 kc, single speaker
Code 223 - 520-1500 kc, twin speakers

Code 125 - Mentioned in 1934 Philco parts catalog, no other info found as of yet. Educated guess here: Probably has cylindrical tube shields over front end tubes, single speaker, and shadowmeter.

I have two 71 chassis down in the "archives" here. Both tune 520-1500 kc, both have the large "hood" tube shield. One is a Code 223, the other is missing its identifying decal but appears to be another Code 223 set.

[Keith Park]

Interesting!

I have a 71H code 221 downstairs... thats the only 71 I have right now.

Keith

[Ron Ramirez]

And a fine looking set it is indeed...folks, Keith's 71H can be seen on the June 1932 page of The Philco Radio Gallery on this site.

I forgot to mention, Keith, that Model 89 (and Model 19) were put on the market in January 1933, so it makes sense that Philco began manufacturing the sets in December 1932. Thus, your 89 must be a very early production model.

[Keith Park]

Thanks,

Yea, I like the early version much more than the late... and it works quite well too. The only change I made was lowering the resistor to the oscillator cathode to make sure it stays stable.

Now... do I keep this one in the collection to put along side the 16B Im doing later in the winter ??

Hello,

I found this thread while looking for information on Philco 71 code 125.
I don't know much about this set, as I'm quite knew to vintage radios. Long story short, a friend of mine, who's an accomplished cabinetmaker,
wanted to try his hand at radio cabinet restoration, so I pulled this from storage.

I'll give it to my buddy next time I see him, the idea is that he'll work on the cabinet and I'll work on the chassis.

I just thought that some of you might be interested in images of what appears to be 71 code 125.
As you see, the radio has been modified, I don't know who worked on it, but judging by this effort it has been done
by someone not interested in craftsmanship.

These are the remnants of the old speaker

The radio powers up, hums, but doesn't play. Since I'll have to work on it, I have a couple of questions:

1. Do you know where to get the schematic for it? I looked in the usual places, to no avail.
2. What would be a proper speaker for it? Perhaps a K-7?
3. I looked for this exact cabinet in the gallery, but did not find a match. Close, yes, exact, no.
What would be the year of manufacture?

I'd much appreciate any comments you might have,

Thank you,
Michal.

Hello Michal, and welcome!

You can find a 71 schematic here:
http://www.philcoradio.com/tech/images/71.jpg
You can also obtain a complete schematic package from Chuck at the Philco Repair Bench, which includes all available service info for your set. The price is very reasonable.
http://www.philcorepairbench.com/schematics.htm

Yes, a K-7 is the speaker that was used originally in your 71. I see that someone cut the field coil from the original speaker frame and fastened that to the inside of your cabinet.

I suspect this version of the 71 was brought out in either Fall 1932 or January 1933, since it uses a shadowmeter. Model 71 sets did not use shadowmeters at first, but this feature was added to production sets later on. This cabinet was previously unknown to house a 71 chassis. Yet another undocumented Philco.

Thanks for sharing the pictures! Good luck with your set.

Hi again all,

Just got another 71 chassis on the bench, and its a code 125 too! This time... its a canadian set, 25hz, with the hooded tube shield and a ROUND shadowmeter. One other thing Ive noticed is that the tone switch is not as indicated in the schematic but a 2 part series capacitor in it, one side to ground, one to the switch and the connection between the 2 to the speaker plug. This is in a cathedral cabinet.

[Ron Ramirez]

Hi Keith

You must have a knack for finding 71 Code 125 sets! At least this time it really is a 71, right?

[Keith Park]

Yes, and this time I have the original instruction sheet too with the code 125 on it. Ill take some chassis pix too. strange philco's seem to just pop up for me sometimes! I tried to use the image button to post them but it just add's a IMG test to the post.

Thanks,

Keith
