I haven't measured the voltage under load but I'm assuming that it's
around 8.0 - 9.0v
I'll do some recordings this week and post the files as .wavs to the
list server

yes the matching xformer (600=BD -> 10k=BD) is no longer in circuit
but all the Realistic PZM mods I've looked at suggest the xformer
being taken out since its crap
but I've seen no info on the resulting effect this has on the low
freq response
q: do the Panasonic WM-61A (=BD=3D<2.2k) and/or Transound TSB-140A
(=BD=3D<1.3k) capsules also suffer from this low freq/impedance effect?
