This is just a radio, no need to get too fancy. I assume you have the PP 41 output version. Since you have nothing to lose, carefully open the old one up and see if there are any corroded or broken leads attached to the windings. This happens a lot on some of these old sets. Again these low powered sets are not too fussy about an exact match, go too far off and you may lose power, but other than that, you can certainly try whatever you can scrouge up. Well that's my opinion.
