[R-390] Tube question

[Roger Ruszkowski]

Mike,

The R390 has two RF tubes. The front end of a R390 is a 6AJ5 type tube.
6AJ5's are also used in the first and second oscillator of the R390. 
The R390/A uses 5654/6AK5's for the  first and second oscillator.

I do not have a 6AJ6 in my tube manuals so you mite E-mail to see if thats
a typo for the 6AK6's

Try antique radio tubes if you need tubes. You likely do not need a whole set of tubes
Shop around for your tubes. Prices are all over the place and you can pay way too much.

All:
've been looking at the tube kit for the R390 on ebay. I noticed that he gives 
AJ5 tubes instead of the 6AJ6 that the manual calls out. Does anyone have the 
atasheets for these tubes? I can't find anything on the 6AJ6, so I have no idea 
f the 6AJ5's are the same or not. Anyone know?
Thanks
