Hi,
With all those various Beyer Dynamic TX's upcoming,
I hope this may be a good opportunity to get a few things more clear
and figured it deserved a separate thread.
It's about TX-winding structures.
The 4th digit of the Beyer TR/BV-code system denotes the winding-configurations
of the primary and I'm wondering about the virtues & possibilities this can give.
'0' denotes a single primary
'1' center tapped primary
'2' two split bifilary wound primaries
'3' two split bifilary wound primaries, end of winding 1
connected to beginning of winding 2 and led out as tap
'4' two split wound primaries
http://home.hetnet.nl/~chickennerdpig/FILES/BD_4th_mq.jpg
So the only difference between '1' & '3' looks to be the bifilar-winding of the latter.
And alike for the difference between '2' & '4': the former is bifilar, the latter is not.
I've read the various info around (here, RDH, http://en.wikipedia.org/wiki/Bifilar
etc etc), but some remaining questions are:
#1
I'm wondering if there are any advantages of non-bifilary windings ?
In other words, why do Beyer even make the non-bif.types '1' & '4' ?
#2
Can bif-wound split primaries be put in parallel just like 'normal'
split primaries ?
(so resulting in a fourfold ratio-change compared
to the situation with both primary windings in series)
Thanks !
Peter
