I have one of these:

A previous owner/repairman in Lima Peru had changed the tube sockets to accept octal tubes for some of the tubes, and hacked in an autoformer in place of the ballast. I took that out, did a recap, and used a capacitor to drop 230V@60Hz to feed the heater string. And a resistor to drop some the 230VAC for the rectifier (you get more B+ in 230VAC mode, which makes for more audio output with a 35L6 (the above octal replacement) and some more gain for the front end and IF amp.
