5Y4GA/GT from Findatube.com:
NOS - $5, used/tested - $3

If you want the ST style 5Y4G (taper-top or, as some people call them, "coke bottle" shape):
NOS - $8, used/tested - $4

The "solid state" tube is probably two silicon diodes soldered into an old tube base with no current limiting resistor, hence the warning to "use a 'standby switch' in the high voltage circuit". If the proper current limiting resistor is used, there is no need for a standby switch. You could make your own solid-state replacement for a 5Y4G...or just buy the tube from Findatube.com .
