Last Magnetophon recorder - TFK M21

TFK M21 with Vari-Stand

        M21/M20 were the latest generation of AEG/TFK magenetophon master recorders.  I am lucky to collect one M21 to compare with my modified Studer A80R.

Optimized for 15/30IPS

Complicated head module design; quite different approach compared to
Studer A820/812

Asymmetric butterfly heads 

Heavy die-cast frame as TFK M15/10

Three layers constructions
