...If anyone else has some cheapish and good (or just fun) rectifier options, please let me know. Trying to build up an assortment. Don't worry, I won't hoard them, just grabbing a few here and there that look interesting.
I like the 5Z3, the 4 pin version of the 5U4. Just get a 4 to 8 pin adapter and you can get 40's and early 50's RCA, Sylvania, National Union etc., often JAN or "hanging filament" for a fraction of what the 5U4 version would cost.
Another "tube less traveled" is the 83V (note the 83 "no V" is a mercury vapor tube and not anything I would want to mess with). It is the 4 pin version of the 5V4 aka GZ32 and nice examples can be had for a lot less than the 8 pin versions.
