            Hi

A service tech can repair them, but at least ask for some diode protection

on the rails and a recap and new regulators..

The whole power supply could do with a redesign from scratch, which can be

done but takes time due to all the various voltage rails. 

One approach is a new PCB to replace the old one, but that still leaves the

high voltage drop into some of the regulators.

 

Regards

Rob

So is it possible to create something different for it when it comes to the

PS ?



I mean – is there another existing design or will my technician be able to

come up with something himself ?



Thanks in advance;



Kenneth

Hi Kenneth

Same fuseholder and same fuse will be ok.

The constant noise from the power supply is because its one of the worst

ever designed....

It is truely awful with parts under huge stress and no care over the audio

power, or in fact the digital power.

No protection either, so when it fails it causes a fire in the front panel

boards...



I have a couple to restore for a client, but to be honest its junk. It needs

a totally new design.

If the noise is 50/60Hz check if its the transformer windings humming...if

so you need to replace the transformers.

Does anyone know if it's the same fuse type that's used in the Emulator 

II as in the original Emulator ? 



When I got my Emulator it came with no fuse holder and fuse - and so 

far it's been working with a fuse similar to the one used in my 

Emulator II.



But I wonder if it could have any influence on the constant noise 

coming from the power supply on my Emulator ?



Does anyone know ?



Thanks;
