emulatorII-list

Thanks everyone for your replies and tips.  

I guess I will try to clean/reseat the ICs first and see what 
happens. 

In case it won't take care of the voice problem...I read somewhere in 
the forum that the S3528 is the one to replace if a voice cuts out. 
Then somebody told me it's the SSM2045? Are these chips located on the 
analog board? And how can I isolate the problem so I know which one  is 
bad? 

I found these chips on www.Vintageplanet.nl  The S3528 chip was labeled 
s3528B. Does anyone know the difference and if the S3528B will work 
also?  

George

Hello George,

another machine which contains the SSM2045 is the Oberheim DPX-1
Sampleplayer. I think this would be the cheapest way to get these
chips and also an 5 1/4" and an 3,5" diskdrive, which also works with
the EII. I`ve tried it successfully with the drives of my DPX-1.

Regards
Heiko

the unit (do not use the main output). Go through the 8 outs one at a
time to see on which output there is no sound, or maybe some fuzzz..or
even a high-pitched ringing instead of the sample. This is the easiest
way to check possible bad voices, and without any tools needed. If you
do get a bad sound from one or more of those 8 individual outputs,
then I would say you most likely have some bad voice chips. The next
step would be to open it up (via the 8 or so screws around the
bottom-edge of the unit) ..lift the top up, and you will see the
output board

need to remove the power supply (via 4 screws on the outside back) to
get to the SSM2045 chips, unless yours is the "European model" with
the power supply on the right-hand side? much easier ;) Anyway, you
will see 8x SSM2045 chips located at the top of the output board
either way. From Right to Left they are 1-8 so if the output on #3 and
#5 have bad sound coming out of them, then you know that the 3rd and
5th SSM2045 chip may be faulty. Now try swapping the bad chips on #3
and #5 with any of the good channels #1 #2 #4 #6 #7 or #8. If the
chips on 3 and 5 are truly bad, the bad sound will follow them
anywhere you swap them. Hope this helps!

Hi ! 
i've just opened my emulator II, reading what you said about the ssm2045 chips. .... What if on the main output, the sound becomes wierd, after 10 minutes of perfect use ? i plugged the jack into each voice output, and the keys were the sound came from ( aleatoire ) produced the same wierd sound as on the main output. but only after about ten minutes of use, i can't understand what's going on ....
what else could that be ? should i replace each chip of each board ???
thanks a lot everyone if you have any clue, and some time to read this sos message.

best,
Adrien

This sounds like when heat builds up, the connection on some chip 
deterioates.

Have you reseated all connectors and IC\ufffds ?

Not sure if this is relevant to your problem, but I always start with the power supply.  Since its modular I just take it out send it to a shop have it rebuilt. A faulty PS will cause so many problems. I would not attempt trying to repair a PS yourself unless your qualified to do so.
