in the first instance, that is what i will do. i have connected up a tsb 120 in 
place of the original capsules, and it works all right. later on i might want 
to power the microphoness with a separate battery - so i can use the follower 
circuit - but that will be only to lower the distortion levels.

Are you hoping to operate the Transound 120A capsules on the existing 
H2 electronics?

For those able to access micbuilders's files, here's one of 
Umashanker's "Soundfield" arrays made with TSB-120A's:

Do you think Transound's spec of 28 dB(A) self-noise is correct? Rob D.
