Philco 623
#6

If your radio uses 90V and 1.5, there are some very nice schematics for building your own power supply using A/C power. Built a couple for my farm radios and they really work well. No batteries to change out. Cost for parts really cheap. You will spend more for the aluminium box and the perf board. Can turn out looking exactly like an original battery with the graphics applied.
Good luck, nice looking radio.
