BL1 vs. BL2 Balun

[crstrode]

Aside from the switch to change from a 1:1 to 4:1, what are the differences between the BL1 and BL2?

I've never seen either, however it appears to me that the BL2 has two binocular cores, and the BL1 has a single core.  Is this so?

By the way - does anyone know the specs on the binocular core?

I'm guessing it is a mix 43.

BL1 is only 150W, BL2 = 250W - but it looks like Elecraft have dropped the
BL1 now, not on mini module page or in order form

Question: Aside from the switch to change from a 1:1 to 4:1, what are the differences between the BL1 and BL2? I've never seen either, however it appears to me that the BL2 has two binocular cores, and the BL1 has a single core.  Is this so?

Answer - The BL2 is rated at 250W.  The BL1 was rated at 150W. The BL2 is a little higher because of the two cores. I have both the BL1 and BL2, and also a modified BL1.  I ordered the BL2 blank PC board and the slide switch and mounted the core from a BL1 on it and ended up with a switchable BL1.

I would like to someday change those round plastic adjustable screws to screws with wing nuts.

Please accept my apologies if this is a duplicate post - there seems to
be some problem with the list accepting my input (I've got the same
problem here at the office with my Boss :-)

I'd actually like them to be banana sockets, sine I plan on using my BL2 in
a portable situation with a inverted V fed by ladder line, so I can make the
connections up and just plug & play.
