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.

Subject: SV: [emulatorII-list] Same fuse type in Emulator and Emulator II ?



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;
