[ARC5] Reverse engineeing the BC 456

[J Mcvey]

My idea to to modulate the bc456 with a 'level shifted" electret mike hit a snag.
The mike input transformer has ratio of 1:10 primary to secondary which is terminated with about 3000 ohms which means that the primary is looking to match a 30 ohm device?
That explains why the modulation is so poor. My T-17 likes to be around 2K.It also precludes using the electret output directly because the internal fet needs a drain resistor of 2- 5k to provide the gain, requiring a medium Z to match.Bummer...Nothing is ever simple...
