The alpha-numeric 7 Segment LED display sometimes won't display the left portion of the left display, which can make it difficult to tell patch 68 from patch 58 etc. The current picture shows all 7 segments of the LED working properly. The problem is intermittent. I do not solder so I have not fixed it.
Some various scuffs, nicks and worn finish underneath (See Pics)"
"Here is a MemoryMoog Plus that has the LAMM upgrade. It was upgraded in 2006, and while it was at Rudi's shop, he asked if I wanted to upgrade the LED's to a brighter red. I asked if there were other colors, which he replied 'yes', so I went with these ultra cool blue LED's. More info can be found here. http://www.lintronics.de/lamm.html"
"Here is a perfect example of a TB-303 modified by THE BEAST. It is in perfect working order and in mint condition. It looks brand new! There are only seven in the world, this one is the second one 'zero zero two'. It sounds amazing like a original 303 on steroids. The Devil Fish & The Borg don't even compare! Unbelievable! I Hate to part with it but I bought a house this year and I need money. For more information go to: http://www.thebeast.co.uk/303/index.html"
"bought new in 1980 at Caruso's Music in New London Ct... This unit is a 2601 Rev3, which is the very last revision of the 2600. It comes with the 3620 keyboard, which is duophonic. The last 1,000 units made were 2601s and only the last 100 or so were Rev3. They are quite rare. This is important, because the Rev3s did not have potted submodules, so they can be worked on. The rev3s were mechanically superior to the earlier models. Some people do not like the later filter as much, but that is an $99.00 upgrade from CMS. I like the sonics on this one, I have never found it to be dull or noisy, so I have never modded it.
The following is from CMS audio. (a respected 2600 repair/mod shop)
The best 2600 to look for?
Chronologically, 2600's got more reliable and serviceable as production progressed throughout the 1970's. The biggest change was the 2601 update that replaced all the input jacks with a more reliable type of jack. However, this improvement required that each jack be hand wired to the circuit boards, pushing up the labor costs considerably. The printed circuit boards were fitted with additional supports that improved the tactile feel of the sliders and also improved mechanical reliability. The retail price of a 2601/3620 was $3300.00 in 1975.
Probably the best course would be to find a late model (2601) and get the audio upgraded here at CMS. The earlier units do sound better from the factory, but the numerous mechanical problems can add up to a hefty repair bill especially if the 2600 in question, has been exposed to moisture for long periods.
Extensive road use is obviously another cause for concern. Indications are a yellowish silkscreen (tobacco) and a worn silkscreen in the filter mixer and ADSR sections."

via this auction "This never sold new old stock Snare P.S. synthesizer drum machine recently discovered in our 40+ year old music store is in fantastic cosmetic condition. All controls seem to work fine, but two pads work and two do not. The neoprene drum pads and slider knobs have deteriorated and will need replacing. Amazing variety of sounds and tones. Sold as is for project, parts, or repair. Comes with the original owners manual and sales brochure."
