I'm surprised that no one mentioned the 1928 era "Philco Socket Power B" supplies. Mine was seriously damage by acid leaks so I gutted it and was able to install a modified ARBE III supply. No holes were drilled in the front panel and only one binding post added. Configuration and access to the ARBE taps are easily made by opening the top.
