Greetings from Oberheim Regarding the memory mess. This may or may not help but is worth checking before sending your Echoplex back for repair. 1) It works great with factory memory. 2) The memory is upgraded. The Echoplex doesn't work right. 3) The original memory is reinstalled and it still acts funky. Some of the malfunctioning seems to occur after touching the or jarring the Echoplex. Here is a possible solution. There are 7 screws holding the top on the Echoplex. There are 4 on the back, 1 on each side and 1 on the front. All of these screws should be the same length except the one on the right side (looking from the front of the Echoplex). That screw should be just a fraction shorter than the rest. Unless you are really looking for it, all the screws appear to be the same length. When a long screw is put into the right side, it can come into contact with the core of the transformer. It seems to mess with the magnetic field somehow and it makes the Echoplex act kind of spastic. Jarring and touching the Echoplex can make it reset and act unpredictably if a long screw is used by mistake. This may or may not be the problem but you might check out. Hope this helps.

(???) I'm not saying what the issue was, bad memory or otherwise, I just know that my EDP was not in great working condition. I noticed the problem started after I installed the new memory, then when I switched back, I still had problems. It could have been a cold solder made worse by flexing the board when I installed the new memory, I don't know ... I'm not going to make any judgements until I hear back from Oberheim. My only complaint is that I've been without my EDP for over month now, which is not Oberheim's fault. I mistakenly took it to a "qualified service center" when I should have shipped it directly to Oberheim to begin with. I have an e-mail in Mike Ayers and I should hear back soon. Some typical problems I saw ... when I hit overdub, the EDP would sporadically switch into multiply mode on it's own, then it would hang. Sometimes I couldn't get the EDP out of overdub without hitting the switch several times. Sometimes the screen would turn into giberish after letting a loop run for a few minutes. On Kim's advice, I took the EDP in for service and hope to get back a 100% working EDP. I also sent the suspect memory along with the EDP to see if that was possibly the issue. I hope to get it back soon ... >>-----Original Message----- >>From: Bret [mailto:echoplex@yahoo.com] >>Sent: Monday, August 10, 1998 10:19 PM >>To: Loopers-Delight@annihilist.com >>Subject: Re: RE(2): Echoplex memory mess... >> >> >>If the unit works as you say ("the unit worked fine with the supplied >>50secs of memory"), fine with one set of simms, and not another then >>the simms are to be suspected, not the EDP.
