RF Parts sells 3 different chimneys for the 3-500;  the are 4, 4.25, and
4.75 inches tall respectively to accomodate (among other things) recessed
sockets.

Ameritron sells the 3-500 chimney for $22, which is substantially less than
the above. This model is also used with a 1200a7 and a recessed socket.
