Hi. I also have a 623 and will be restoring it: http://philcoradio.com/phorum/showthread.php?tid=5384

I haven't started on the battery eliminator yet, but I have the basic design in my head. I'll be using a transformer salvaged from an old tube TV. An LM317 (or LM338 ) for the filament regulator and an LR8N3 HV regulator for the B+ based in this design - http://www.antiquewireless.org/otb/resto0504.htm
