Title: Power Supply Post by: mellowthunder on February 28, 2010, 09:21:59 AM Anyone know where I can get a power supply for the EII or get one repaired? Any repair centers in the Los Angeles area that can repair them?

Title: Re: Power Supply Post by: rokuez on September 01, 2010, 01:38:02 AM Yes, that is a good question. I would like to know also. bump i'd also like to know eii user in la here Title: Re: Power Supply Post by: ditabeardmemo on September 01, 2010, 09:47:41 AM Bruce Forat of the Forat Brothers still services the Emulator II (and other E-Mu units) in the Los Angeles area, but as has been noted here before, he is very expensive.
Speaking personally, I had Bruce refurbish a LinnDrum II that I bought in non-working condition, and I thought his craftsmanship was excellent. But again, the bill was not cheap. Title: Re: Power Supply Post by: Dimensional Space on September 01, 2010, 02:28:16 PM .

Title: Re: Power Supply Post by: Elmbeatz on September 06, 2010, 05:44:02 AM The EII PSU is neaderthalic. Change it ! Change it with what? Title: Re: Power Supply Post by: dr.c on September 06, 2010, 06:49:35 AM There MUST be some compatible PSU, even noy forceably by the pinouts, but by voltages and current !
Title: Re: Power Supply Post by: Elmbeatz on September 06, 2010, 07:20:02 AM Doctor,
If you don't know, nobody does. ::) Title: Re: Power Supply Post by: Zomnius on July 23, 2011, 01:46:05 PM Dr what are the specs?
Title: Re: Power Supply Post by: dr.c on July 24, 2011, 10:03:01 AM I am going tonight for a week.
Everything at Forat is expensive. When they bought the Linn machine parts when Roger Linn went out of business, everyone was calling the "Four rats". And still do... I am going to dig in my documentation and will telle you ASAP, by august 3rd. Cheers Title: Re: Power Supply Post by: 80sboy on July 27, 2011, 01:07:13 PM I just went to my friendly neighborhood electronics supply place to get caps to rebuild the power supply and they talked me out of it. They said there should be a replacement for it new. Has anyone tried inputting the specs into the mouser site? I was able to replace the power supply in my studio 440 with one from Mouser, and it seems like something that can be had for the EII...
http://www.mouser.com/Power/Linear-Switching-Power-Supplies/_/N-wp5h/ Anyone?? http://www.slpower.com/data/collateral/GPC130_DS.pdf ??? Title: Re: Power Supply Post by: Elmbeatz on July 27, 2011, 03:07:11 PM ... Anyone?? ... Man, that's way too advanced stuff for me, but if you find a modern replacement psu, you'll write history!! :o :P Title: Re: Power Supply Post by: 80sboy on July 27, 2011, 03:58:46 PM I'm pretty sure this will work. I found one pretty cheap that I'm going to pick up. UNfortunately I'll be working on location for almost the next 2 weeks so the suspense will kill me!
According to the specs it outputs exactly what the EII wants to see, it's just a matter of hooking the wires up right. The transformer in my power supply is making funky noises, and I'm not entirely sure that just re-capping would fix that, I'd hate to spend the time re-capping the entire thing to find out it didn't help. The Condor supply is medical grade, looks pretty nice. 80sboy Title: Measuring Wattage Post by: 80sboy on July 27, 2011, 04:40:11 PM If anyone who has a working EII and happens to have or can get a kill-a-watt device to measure how much power the EII is drawing under load (disks loading, playing etc...)
http://www.amazon.com/P3-International-P4400-Electricity-Monitor/dp/B00009MDBU/ref=sr_1_1?ie=UTF8&qid=1311809852&sr=8-1 That would help determine the maximum size power supply required. I've only found one reference to the supply being mentioned as 150W MAX. If under load we find that it's really only drawing half that or whatever, it would help me determine if the power supply I'm looking at is big enough. Thanks! 80sboy Title: Re: Power Supply Post by: 80sboy on August 23, 2011, 04:42:45 PM Update:8/23/2011
Picked my EII back up form a great tech here in the Bay Area www.thisoldsynth.com Power supply up and running now! What's left is to pull all the chips on the boards and clean all the sockets and legs, there is definite tarnish/corrosion there. Chris recommends Isopropyl, with maybe a little deoxit - is there a good standard procedure to get all the corrosion/gunk out of the IC's? Also just received a DPX-1 in the mail today with a bunch of EII disks, so double wammy. AND also picked up from repair a Drumulator, working great now, with MIDI and the JLCooper 3 Chip kit installed! Budget Linn! Time to re-arrange the studio......again..... 80sboy |
