2 things: 1- just had my OBXA open, and i'm 99% sure the only tants are in the PSU. 2- just being honest here, but if you just want a working synth, you're better off just servicing your OBXA. if you are intent on going down the synth resto rabbit hole, i can guarantee you that about 50-70% of the r...

thnx. successfully cleaned with alcohol and disassembly, fyi.

hey folks, so two of the switches(filter mod depth, and OSC 2 mod depth) were not working on my OBXA. i've had several logic IC's go south on obies in the past, so i guessed that it was an encoding issue, but through continual depressions, i was able to get the filter switch back to working. so now ...

wow. nailed it. spot on. open + on the rectifier board. all fixed up now, looking sharp-thanks!

hey folks, i just got a model D, and need some help. problem: there is a constant drone at both the phones and audio outputs. its roughly around F1 on a piano, in pitch, i'd say. diagnoses: -if i turn on the A=440, it doesnt produce 440, it seems to change the timbre of the drone. -the filter sectio...

@Mr Knesh Fair enough, but then why buy any new piece of gear at all? I understand your point. But I still disagree. I made a TON of music with nothing but a Roland EM-10 and an 8-track recorder. I purchased other equipment to modify the way in which I made music, but the gear was not the device wh...

i kid!

Next up: hammers that made an impact on carpentry.

hey all, has anyone ever had to source a panel switch for a synthex? is there a drop-in replacement out there? anything use the same switch maybe? something in the switch assembly of the 5811 board on this synthex is pushing the data buss lines above +4V. i'd like to replace the switches. thanks for...

thanks!

hey all, has anyone ever sourced one of these anywhere? mouser, digikey? i think i may have to find a white one for a synthex. thanks, rj

oh, and someone really needs to grab that rehabbed synthex-rare as hens teeth and a killer synth!!!

hey, would you mind doing me a huge favor? sorry to pipe in here, but i see you have a synthex out with a tech, and seeing as how these instruments are so rare, it would be REALLY hugely helpful if you ask him just one simple question: on the PSU, what size bypass caps are #1 and #2? on my synthex, ...

CS-80(no im not kidding), Rogue or SY-2.

hey folks, so i am trying to get the PSU on this synthex up and running. it currently has the +12v and -12v rails working, the +2.5v, +5v and +6.8v rails are down. 2.5v and 5v rails both read +1.5v. here is a link to the full schems, PSU on page 3: http://www.sendspace.com/file/lf9j65 here's what th...
