airline15

Hello all,
Last year I picked up a airline 15 and decided to see if the thing works or not.
Can't find a correct schematic on this set. Riders says it's a 120 volt set, but this is a battery set. The closest I found is a u-15.
On radiomuseum the pictures for the model 15 are the same thing I got, but the schematic shows the set is 120 ac with a transformer Again this is a battery set.
It has 5 201 tubes. Hookups are aerial, ground, speaker, a+, a-,B+, B-, B+ det,
B+ amp.
The u-15 has voltages listed as 90, 45, and 6.
I believe the 6 is the "A" voltage. Anyone know what the "B" voltages should be?
