Hi

This Minimax pre looks very good value for money. It can be had for £699. It is now imported by shadow distribution.

Looking at the pictures of the insides, there is a choke in the power supply which looks like it could be choke input but not sure.

Like most things, further tweaking and modding can be done but with it being small in size it can be a bit cramped.
