Philco Model 89L, Code 123 project
#1

My first recollection of radio in my life accured when I was about 4 years of age. I can vividly recall standing in front of my parents Philco floor model radio and listening to the music that was being broadcast from WMEX Boston. My parents had this radio in their home until the end of the 1940's when we got our first TV. Many years later having retired and a lot of free time, I decided to locate the exact model radio and restore it to use for "old time sake." Over time I found several being offered on ebay, but they were located far away and I was reluctant to have such a radio shipped to me. Some were closer but the cabinets were a disaster. Fortunately I found one 10 miles from my home and the cabinet was in excellent condition. The only thing missing from the radio were the correct Philco rosette knobs (which I can get). The radio still has the original Philco tubes! When I was in the business of restoring antique auto radios I worked on numerous Philco auto radios from the 1930's and in doing so I used the Rider manuals and diagrams as my guide. They weren't always easy to use, but they served their purpose. I am quite familiar with the Philco radio characteristics and thus was looking foward to a memorable experience with my newly gotten Philco console. However that joyous anticipation quickly came to a halt once I immersed myself into my endeavor. The radio I am hoping to restore is a Philco Model 89L Code 123 from 1933, a year in which I have discovered Philco made a number of changes during their production runs. The chassis shares some general similarities with Philco auto radios of the 1930's, but not in all areas. Household radios it appears are more of a nightmare in some instances! I have also learned that some consider this model to be the Philco radio from H***! (I haven't gone but a little ways in my efforts and have learned why this radio has that reputation!) I have the Riders volumes on CD and searching thru them have been able to print some diagrams. Alas! All but one of the diagrams that I have been able to attain agree with the chassis configuration that I have, (I got that from the internet) and that diagram along with the pictoral layout drawings are of poor quality due to "fuzziness" and blurring of printed information or images. My hope is that there exists somewhere in Philco Land a source for schematics and layout data that can be more readily understood by two very aging eyes! Any suggestions (or hints) would be much appreciated. BTW, I'm sure that this model radio has been discussed before on this forum and if so I am reluctant to bring back and old chestnut, but I find this forum to be my best resource for info. Thanx, Hal (Ex W1DRW).

Welcome to the Phorum!!!

Chuck has excellent schematics and any documentation that was printed about changes for just a few bucks.  Well worth it. See http://www.philcorepairbench.com/schematics.htm

Also Ron has outlined the evolution of the 89 cabinets and chassis here

Something else you'll need as you restore this radio: Bakelite block condenser information.  Find that info here:

and info on rebuilding/stuffing the bakelite blocks here:

Hi Hal, welcome to the Phorum!

For a six tube radio, the 89 is a good performer. Don't let the stories scare you away. The oscillators can be a little finicky. Usually, baking the oscillator coil to dry the moisture is all it takes.

Hi Hal, I somehow missed this post - but your first post reads much like I was thinking when I first started looking for info for the 89B I have... there aren't too many chassis photos out there, and most of them seem very small or blurry. And I quickly ascertained that I couldn't ascertain the run number for my one... so decided to push it through to the second-to-last run on Rons history of the 89 here http://www.philcoradio.com/tech/89evol.htm just because I want to use this as a 'daily driver' once its finished. I would have gone to the last, but I didn't have a 350k switched pot, so left it with the on-off switch on the band selector but left enough wire to change it later if I find one.

There is another 89 on the forum at the moment, and I made some comments there about what I would do if I was just wanting to get it up and running - it might be worth a look: http://philcoradio.com/phorum/showthread.php?tid=13400

And my rebuild thread is here http://philcoradio.com/phorum/showthread.php?tid=12777

There is also a range of photos from the first look through to a finished (mostly) chassis in my Photobucket account - you can access that here: http://s241.photobucket.com/user/4wdstuf...Code%20123
The photos should be high enough resolution for you to see what it started as, and the process I went through. If you can't see them clearly (photobucket is not the easiest site to navigate - I'm not fond of it, but its handy) then I would be happy to send a CD or USB key over to you with the photos on it or just move them to a big zip file online that you could download. They were very helpful to refer back to when I was reassembling mine... but I did go a little mad on the rebuild Icon_smile

Performance-wise, I've been very happy with it. I live out in the country but can get a good range of local(ish) stations without an aerial... adding a very short piece of wire to the ant clip almost doubled the volume of those stations... I have not tried it with my long-line aerial yet but I'm expecting to be able to listen to overseas stations easily at night with it (even though the SW band is very limited).

My cabinet is still trashed... I'm still figuring out what to do there. Are you able to post some photos of yours?

Cheers

Steve
