Yes, MrFixr is correct about the speaker being connected to the output tube via a coupling cap. I restored a 514 a few years ago and discovered the impedance of those old speakers is 2k-2.5k. The speaker on this one was in bad shape so I used a two watt universal line transformer which gave 2k pri to 8 ohm sec. Connected an 8 ohm modern PM speaker and it worked great. Even mounted great in the old enclosure.
