Philco 89 (code 121) parts list
#1

I have looked for this and hope I haven't missed it somewhere. Can anyone point me to a parts list for the Philco 89 Code 121 cathedral? There is a bottom view of the chassis showing parts in Riders 3-34 with the schematic on 3-33, but I cannot find a page telling me what the actual parts are. I am mainly wanting to know the capacitors before pulling the blocks out. I know I can look at the block numbers and figure it out, but sometimes you have to pull it to see the numbers. I see a parts list for the 89 code 123, but numbers are different.
Thanks,
Scott

Welcome to the Phorum! Icon_wave

Here's a must view link: http://www.philcoradio.com/phorum/showth...?tid=15002 that has the evolution of the model 89 showing the changes in the circuits over the years. Ron, our founder, put this together and should be very helpful. It does not have a list of parts but the schematics are very readable.

Also try: http://www.audiophool.com/Philco.html where you can view Service Bulletins #146 and #146B. They have lists for the 121 and 123 respectively. you need to download the djvu reader to view the images. If you have trouble let me know.
