UK Vintage Radio Repair and Restoration Discussion Forum - View Single Post - Correct Microphone For Sanyo MR-212 ?

I recently acquired a Sanyo MR-212 Mini R2R Taperecorder (Pic: #1) and after a bit of servicing it's working well.

However it didn't come with a microphone but I've seen a picture on the web of the unit with it's mic and this looks like a dynamic type.

I have quite a collection of mics, some crystal type & other dynamic types (of various impedances) but the audio quality from them varies. The one that gives the better result is a Sony F96 low imp type (about 200R).

From the circuit in pic #2 can anyone advise what impedance is the Sanyo MR-212 designed for?
