Re: Uher 4000 Report Monitor Noisy
Feedback from SDS is that MIDE originally was a special option for an Italian customer who wanted the motor to stop when the pause button was pressed on the Microphone during recording to select Remote Pause.
SDS do not have the technical details of the MIDE modification but say just some simple mods to the Control board and they have provided me with a photo of a MIDE modified Control board. From the photo can see that 1 transistor has been added plus 1 or 2 resistors/capacitors and maybe removal of a couple of resistors/capacitors, also can see at least 1 extra wire connecting to the board (assume this may go the motor control board). May or may not be connected but I noticed on the large 4000 schematic I purchased from SDS a while back that there are a couple of extra diode inputs (with no external connections) shown on the motor board compared to the only other 4000 Remote Monitor schematic I have seen (downloaded Hungarian schematic) so wonder if these extra inputs may have something to do with the MIDE modification. SDS do not know what MIDE stands for, they thought possibly linked to customer name ? David |

Re: Uher 4000 Report Monitor Noisy
The Uher 6000 Report Universal schematic (vintageshifi) shows a motor stop mod. for when pause is triggered, the mod. it's just one transistor and a resistor which shuts off the motor supply transistor when pause is triggered.

Fascinating! I hope SDS get a kick out of us lot asking them questions about obsolete machines and them being able to answer.

Another good find Lawrence, I will study that later.
