Title: AKG C28C transformer changed?
Post by: wdevlieger on November 29, 2017, 04:41:38 am
Hi.
I was wondering if a AKG C28C has the same T14/1 transformer as the C28A and C28B versions (and C24, 251) have.
I know the "C" version has a different circuit compared to the "A" and "B" versions, but I'm not sure if the transformer changed as well.
Does anybody know this?
Thanks.

Yes,
The C28C has a different transformer that its predecessors, C28 and C28B, due to the use of a Nuvistor as impedance converter. But, other than all other AKG Nuvistor mics, the C28 C did NOT use a cathode follower circuit.
