Smoking and noise "Emulator II"

[DARKSHINE]

I sometimes during play (1/20 turn on )
volume come down, and the buttons do not respond

I am obliged to turn off and on again
because the volume sound is very down

is what can come from a voltage down ?

I find this:   http://www.synther.org/emulator2.html

a new power supply with a fan     ! ! ! ! !

They used a meanwell 50C power supply.. No need for the fan however.. They run rather cool.

They are great power supplies too.

One of these?

I need repairs on my EII PSU... A nearly drop-in solution solution like this would be perfect!

Is 50W max power with 5V @ 4A, +15V @ 1A, and -15V @ 1A going to be enough?

Looking a bit closer at the photos, it looks like the replacement PSU is this one:

Mean Well T-60C, 5V @ 7A, 15V @ 3A, -15V @ 1A

I installed the Meanwell T-60C yesterday, just as shown in the links above, and it works. The EII was having issues with no sound and now that problem has disappeared.

I bought the T-60C from Jameco.com for $35. Well worth it!

Great.
Thanks for the hint. Seems like a nice replacement unit.

Could you take a picture of the Meanwell installed in your EII, with all wires connected ?
And perhaps also give a short list of the connections you have made (voltage/pin/wire) and modifications (if any, either electrically or mechanically e.g. screws)
This kind of information is always useful for people who want to double-check whether they have done the installation in a correct way 
Would be much appreciated !

Sure - I've decided to add a Meanwell 12V PSU as well, just for the floppy drive. The Shugart recommends a supply of 12V +/-1.2V, and the 15V I have now is a bit outside that range. There should be lots of room in the EII PSU ledge/platform to put both Meanwell units in there. I'll get photos after I get the other PSU in. It should be here in a week...

Any update to this?
