Memorymoog Plus HELP
2003-12-21 by oxygeno13
Hi,
I have a Memorymoog Plus, but i have a big problem, i hope anyone can
help me :
- I was using a Roland SH-5 and controlling it with the MM+ via CV
gate and sending a MIDI from a sequencer. Everything was working
good.
- Someday i turned on the MM+, i hit the autotune and the display
said "ZERO TUNED" ... some other day i turned on and nothing
happended... no sound, no controls, no display , just the MOD RATE
LED and AUTOTUNE was lighting.
- I opened the MM+ and checked everything, i revised the bulletins
services, and i found that almost of the upgrades were made, maybe
some of the upgrade came from factory and others were made my some
technician, the only upgrades that are not installed are the 842A,
843, 844, 845. The bulletin 846 (Alphanumeric display) is installed.
I noticed that the bulletin 843 talk about the ZERO TUNED. I checked
the Power supply voltages and everything its OK.
- On the CONTOUR/GLIDE board i found flux oxidation at the front of
every IC sockets (74LS08NS and 74LS32NS) I cleaned the sockets and
the ICs, but the problem still . I replaced the sockets and new ICs.
The problem persist
- I was thinking could be the EPROMS.
Im a hardcore DIY, i fixed many vintages synths and drum machines,
but this one is really a Frankestein (hehehe).
Hope can help me with this... i paid 1800 dlls for this synth, and
now its not working... i would like to S&H to Moog CE or any other
Moog technician but now its very very expensive for me and i really
dont want to pay more money. Well, i can pay for the support if any1
want and have the time, i really need help. The older owner of this
synth paid $1000 dlls for a repair, he sent the MM to Hollywood, i
have the original bill, he gave me that bill when i bought it. They
changed some CEM IC and the alphanumeric display and the oscillators
tune.
if anyone can sell me a copy of the EPROMs, i can re-program them.
Thanks for support ... !!!
