I like to use stranded wire. If you nick solid wire and have to move later, to replace a part, it may break and you may never know it until you apply power to the radio and find out that you have a problem. That's only my opinion.
I just got done reworking a Philco 89 today. Like you I was a little confused about which schematic to use. My radio had the 36 Osc tube and I finally figured out that I had to use run 13 schematic. I also read through all the changes and anything else I could find on the 89.
Make sure that you check all transformers. My radio had a bad power Xformer and an open osc coil. I did rewind the ocs coil and replaced the power transformer, along with the capacitors and many resistors. I applied power, just today, and the radio came alive. There are still a few problems but I am hoping that a good alignment will cure these problems.
Just take your time, be careful, and enjoy restoring your radio.
