I hope someone can help me with this issue. 

I have an Emulator ll that was sitting unused for many years. I tested it out recently and all functions seem to be working.  However, there are only 7 voices. Whether playing the same key several times in a row or playing up or down the keyboard , the keyboard will only sound 7 times and then the next strike will be silent. Depending on where the 'voice rotation' is, the keyboard could sound 2 times then be silent for one note strike, and then sound for the next 5 times. 
Output #2 has no sound. All the other outputs work correctly as well as the mix output. Plus all of the 'E' keys are dead- Except the highest 'E' key.
When playing the Ell from another keyboard via midi, the Ell's entire keyboard is triggered without any problem or dead keys. But still there are only 7 voices. 
Attempted to fix by removing the power supply section and swapping the voice chips ssm2045 and s3528 from output 1 to output 2 and vice versa. Output 1 continued to work fine. Output 2 still didn't function. So those voice chips are all OK.
 Next I identified the chips below the voice chips that appeared under each of the other outputs. I then swapped those chips between Output # and #2. This produced a random type of voice drop out unlike the regular original dropout pattern.
Not sure what to do, how involved a fix could be and if I should bring it to a tech.
Would appreciate any help I can get.
thank you all

Put back  the chips in place as they were originaly and please, stop messing..

Now, each channler has a chip referenced  S3528

Take the off, DO NOT SWAP THEM, clean their legs (I din't know how to say), and then put them back in place.

Be carefull with the pins (that's tha right name !) not to be bent, chip correctly oriented, and try.

Hi dr.c
I removed, cleaned ( De-Oxit) and re-seated the s3528 chips under each of the 8 channels.It went smoothly, but I still have the same problem. It was worth a try.
Thanks for your suggestion.
If you know of another possible fix, I'm open to it.
Thanks again!!
