Jon,

As a fairly long-term user and responsible for some of the ER material. 
I can hopefully give you some info.  At 90v, the current will be about 
33ma., depending on output level   And, yes, you can push the voltage up 
to probably 100v, or so,  with no issues.  The filamant current is a 
nominal 350ma with the puilot light off.  Add another 50ma for the lamp 
for a total of 400ma.   I wired my receiver such that the pilot light 
switch now acts as a convenient spot switch for the companion 
transmitter.  The lamp is now on all the time.  BTW, the lamp is dim and 
I use one of those clip-on rear reflectors to give just a bit more 
illumination... it helps.  Give a call if you need any more info and 
I'll pass on whatever I've gleaned about these sets.
