Title: Emulator II+HD non active for 10 years Post by: gregre on May 17, 2019, 12:14:00 PM Hi Everyone,
I have a Emulator II+HD that has been non active for 10 years. It was slow at recognizing the disk but now appears to recognize it apon boot. I have since taken it apart and will attempt to clean the key contacts. Any recommendation on contacts, soap and water, isoprpyl alcohol, Q tips. For metal to metal contacts etc., Caig D5? Any battery's, resetting cards, voice tuning etc recommended? Thank You, Greg Title: Re: Emulator II+HD non active for 10 years Post by: dfiorucci on May 25, 2019, 12:39:20 PM Hi Greg,

The main thing is that you want to replace the power supply! It's not easy to find a power-supply that offers +5, +12, +15 and -15 on it's rails affordably. The easy and affordable solution is to build a hybrid supply, that is actually two supplies in one. One for the +5, +15, -15 and a second for the +12. It is always important to connect your new powersupply to a dummy load, allow it to warm up and then trim it's voltages to spec before installation. The other thing that should be addressed in any Eii are the many Tantalum capacitors. They are all ticking time bombs. Fire risk for sure. If you have not replaced these in your Eii, never leave it on, unattended! I have a good friend who's studio burned to the ground because of a fire caused by an failed Tantalum cap! Your keybed will likely need to be removed and serviced. This is a time consuming affair, and takes some skill to do. Each key should be removed, and cleaned (I like to whiten the keys when I have them out) and the key bushing contacts inspected, and cleaned. replace any failed bushings. There are numerous other more technical aspects to a restoration, such as triming DAC's etc. Complex stuff that is best left to a skilled tech. PM me if you need help with any of this stuff ;-) All the best ACE |
