[GreenKeys] BRPE models

[Nick England]

After a little digging, these are the models I think I have identified.
1) The pickup for early models 1-5 were electrical switches, whereas the
"new style" (BRPE6 and up) had a magnetic pickup - the parts books, etc.
make that distinction.
2) The 28v 1a magnets are referred to as "transistor-driven" and the 115v
150ma ones as "tube driven". I thought I saw one reference to 25ma for the
tube-type but that doesn't compute. Also one section of the manual says use
a 6000 ohm series resistor, but that should probably be 600 ohms.

Any additions and corrections are welcome!
