Meta-unicorn post- No leaks ever in either one!! ๐ฆ๐ฆ The 4th P61 and 6th PS6 I've ever seen free of leaks. The key contacts however... Oh yeah and It's a Poly61M. 
The other day a friend asked me about this after a thread popped up on one of those gear forums. It made mention of the lore of a mythical Jupiter 6.8. This one is mine. It's an 8 voice JP6 with a custom ROM and memory upgrade done by one of the engineers that helped design so many of Roland's biggest hits. It's neat. I can't make you one, nor will I make you a ROM due to professional obligation to my former overlords and respect to the designer. But I can tell you it sounds like a JP-6 but two better. ๐ฆ 
Also in today's dive, I found one of the flash duplicators we used at Roland. Copies a master ROM to several EPROMs at once. No external PC needed. 32 and 40 pin adapters included. $300 (ROMs and Files not included) email meeeeee 
Selling off some in house tools and stuff from the Roland Days. The "S Bins" were a black hole Roland Corporate would move inventory and items before they fell out of their system. This is where we'd find weird old gems like NOS TB-303 boards and weird dead stock that somehow got mixed up in inventory. Most of this stuff was trashed when they downsized and the rest sold and given to employees to get rid of. I got into S94 today and found our old hot air rework station and stand, and it was sitting on top of a mass IDE drive duplicator (all your factory ZIP disks and HDDs for VS machines were made here) I don't have the adapters for FDDs. Anyone interested in this stuff EMAIL me (I don't get dm alerts). $50/ea. Local pickup preferred cause it's heavy-ish. Both worked when packed away a loooooong time ago, and still power on but it's an as-is situation.

The elves just delivered more fresh new key contacts for popular Korg/Oberheim/Moog/Sequential synths to the shop. If your synth has iffy keys and these fit, don't waste your time with the paint, just pop these in. It's easy and you'll love em. #polysix #p600 #monopoly #poly61 #poly800 #memorymoog #ob8 #sixtrak #otherstuff 
Here's a synth I worked on today. I generally don't work on new stuff, but I did. I don't have anything else to say about it ๐๐ค #304day 
Mmmm what's on your lunch? #techspread #synthmayo #thisiswhatsinpots 
Dear Foam, Why you gotta be like that? Sincerely, Everyone . . . . . #opus3 #moog 
Hyper bummed about this (customer owned)TR-700. These things sound so good thru their built-in amp and speakers, but this one had a very lively roach community in it, so it has been banished from the shop and me no touchy. Careful buying stuff from the backs of garages and it's probably good to familiarize yourself with the markings of rodent and bug infestations look like if you're a deal hunter. ๐ญ๐ชฒ 
Happy 808 day #808day #808 #day #tr808 
Another successful JD-800 keybed transplant. This time it was a JU-2 keybed . There are quite a few models of donor Roland keyboards that fit perfectly and have aftertouch, so you won't have to suffer a Fatar anytime soon. The key contacts/boards on these are excellent and if you were to even need one, we have lots of replacements. . . . . . #redglue #jd800 #roland 
Fuse repair, or welder mod? ๐คฆโโ๏ธ 
Synths don't get thirsty, and they sure af DONT DRINK WD-40! Seriously WD-40 isn't good for even what it's meant for. Don't do it. #ohihatethisstuff 
THIS IS VARTA(s battery that fits the lexicon 200) 
If your space echo tape makes tight bunches, it's potentially going to get wrapped up in the motor/pinch roller. This happens when the tape is too long, too thin, or bought rolled up in small spools and it has bend memory. No matter what magical properties the seller promises about the tape, this will likely end with service needed. 
Using the conductive paint for repairing key contacts is problematic and not a reliable method. This HS-60 is shedding the paint and is randomly firing notes as it moves around. If you can't get your contacts clean with warm water and soap (not alcohol!), it's probably time to find replacements. 
Installing a @mercurymagnetics transformer in this Jupiter 8. Nice to have a known name in the transformer biz hopping into the synth world. Always weird putting your faith in a no-name transformer when working on high-end gear. Mercury has been around forever, they've made thousands of transformers for a company I've previously worked with and always stood behind their stuff. If you have a 220v unit that you need switched to 120v, I ๐ Mercury! 
Current favorite worst. 
At least that's one Juno I don't have to fix. #conjunction 
I knew I'd seen this tape echo somewhere before 
Oooooh doggie these are not fun to work on, but this one is a few final touches away from ๐๐ #synthatthisangle #oberheim #ob1 
Key issue troubleshooting 101- Dead keys do not mean bad/dirty key contacts. Always important to count 0-8 keys apart for patterns for multiple non-functional keys and look for any spill evidence. This Juno-106 was brought in with 3 dead keys. It turns out it was a spill from years ago that rusted out a make line. This generally shows as multiple keys 8 keys apart. Groups of 8 keys is usually a T-line. Don't just buy contacts expecting them to fix a keying issue without doing a little investigation. When doing this, dont pull up the key contacts til you've had a look to make sure you're not risking ripping these hard to find contacts. All fixed now, and no contacts needed ๐ 
JD-800 keybed transplant! This one got an NOS SK-361UR (W-30/D-50/JU-2) keybed installed and it fits perfectly, w working aftertouch. No more red epoxy leak. Also, not plastic Fatar nonsense. I can do this for you, but you have to sacrifice a pretty expensive synth to make another. This one is for sale at @futuremusicstore . DM for infos 
I rarely if ever bragpost about whose gear I work on, but I โค๏ธ Big Business, and here's their MG-1 in a case. . . . . @bigbigbiz 
Some wire nuts holding this Jupiter 8's power cable in, nbd. ๐๐ข 
This REX-50 took a hit on the way over from Circuitbenders UK and snapped 2 secondaries and a primary off the posts of the power transformer, but I managed to get them reattached. If you have a REX-50 that's dead, I suspect this isn't an uncommon issue. Note: It's very hard to hold the phone, the transformer and the tweezers. 
How many acetones does it take to get to the center of an H3000 (Murata AFL89WB) filter module? They're similar in construction to the Juno 106 80017 modules and acetone does remove the alien goo. I'm not sure if this is a fix at all as the sheild is pretty important in these. It doesn't really work in Juno's either, so I'm reluctant to advise anyone to try this. If you do, don't blame me if it causes other issues. โ๏ธ 
I don't see a whole lot of H3000s, and I've certainly never seen this before. Most have had a laquer or "ceramic" coating that I've seen. Looks like in these versions with these canned modules, the potting material can liquify and run out. It's seemingly slightly conductive (?!?) and also smells sweet when it gets warm. So if you have one of these H3000s, it might be something you wanna watch for cause it's a messy disaster when it happens. It's very obvious as it looks like a pool of goo under these filter cans behind each input and output. 
Flashback to when I thought about remaking Echoplex tape carts. This was a rough 3d printed case prototype with some hand turned poly wheels with bearings inserted. I also made an auto-winding machine for the spools. It all works beautifully, but the idea of splicing a frillion tape loops sucks. Those new ones are cheaper than dirt, so I'll go with those for the foreseeable future. #cantsomebodyelsedoit 
Some JX-3P machines do not work with longer 6P DIN cables for communication with a PG-200. GR-700s and MKS-30s are not succeptable to this . When some guy online sells you a cable longer than 1 Meter tells you it's fine with his machine, and it doesn't work for you, this is why. Or they sold you a crossover cable, but that usually is accompanied by smoke :) #jx3p #enverope 
The one on the right is a real Energizer, and the one on the left is a real ๐๐ฃ๐๐ง๐ฐ ๐ฒ๐ฏโแตฃ with a real 2 hour lifespan. Don't buy batteries on eBay or Amazon, you have no way to know what you'll end up with. If they leak into your gear, you'll spend a lot more than the few bucks you save making it work right again. It's battery week here apparently.
