Just found the 1945 Radiart vibrator replacement guide on line. Might be able to cross and recross.
1945 Radiart Vibrator Replacement Handbook PDF
A bit of looking in the book
105 HZ
6V max 4 amp
Radiart P/N 5428 Base X
A quick reverse look found Mallory P28Y is same thing
Under use it looks grim.
6V Household Sync. 1936
Philco 624, 624B, 624H, 624R
Last page says use a 5411 (fairly common) and note 15 says rewire base from X to V. Base diagrams are all in the book.
