Why The Minimoog Voyager Old School Has Such Short Release Times On Envelopes.

video upload by synthpro

"Hey Guys,
Thought some of you who have the Minimoog Voyager Old School may appreciate this video. I explain why some of the pots may have different responses compare to the models with the computer for presets. I focus on the envelopes in particular in this video but I'm sure there are other knobs that do not behave the same as well."

EMS Vocoder 5000 Repair

"The time has come that bridge rectifiers from the mid 70's can fail short due to age. In this repair I managed to find a blown one and another that was on its way out! This was an RS bridge rectifier dated 1976.

ICONIC Conversation with Jeff Blenkinsopp of The Analog Lab

video upload by Iconic Instruments

"This is a conversation with synthesizer genius, Jeff Blenkinsopp, from The Analog Lab (www.theanaloglab.com)."

CONTROl with co-founder Daren Ho makes an appearance at the end.

The video above comes in via an article on Jeff Blenkinsopp recently written up on Hell Gate. You can also find in on The Analog Lab's blog on their website here. Jeff is the man behind The Analog Lab which provides various resources for synth repair. The site is well worth a look.

From the intro to the article on Hell Gate, written by Adwait Patil:

Below: "Jeff Blenkinsopp after repairing the Beatles' VOX Continental organ, last used at their 1966 Shea Stadium show (The Analog Lab)"

"Jeff Blenkinsopp toured with Pink Floyd and Vengelis, repaired instruments for the Smiths and the Beastie Boys, but his greatest legacy might be his willingness to share his craft.

As one of New York's most meticulous and beloved vintage gear technicians, Jeff Blenkinsopp's legend precedes him. A North England native, he began repairing synthesizers in the late 1960s, worked his way into London’s disco scene as a live stage technician, and later took his talents on world tours with English rock giants Sweet and Pink Floyd, and Greek composer Vangelis. In 1978, he moved to New York, quickly gaining the trust and fixing synthesizers for bands like the Beastie Boys and the Smiths, and carved out a home for the nerds whose vintage gear obsessions were about to peak at the turn of the millennium with his workshop Expert Audio Repair Services, or EARS. At EARS, he devised hands-on methods to pass on his knowledge to some of the city’s most beloved musicians, all of whom came to learn from the guy who became Pink Floyd's synth technician at the age of 21.

Blenkinsopp’s career first took off in 1974, when he was working in London as an instrument repairman for General Electro Music. There he was introduced to Pink Floyd, who were looking for a technician, and met the criteria to join the band's French tour: he knew how to take care of a Hammond, and he had a passport. Blenkinsopp had never toured with a band, and now was in charge of setting up Richard Wright and Floyd's organs and synthesizers on a nightly basis. From then, he became a constant fixture for British bands who toured with a hefty load of keyboards, and that’s what initially brought him to New York City in 1978, touring with British glam rockers Sweet. A tour that changed his life."

This is a video I made during the repair and service of the rare Cordovox CDX organ which featured the Moog Satellite. These are sometimes better known as the Moog White Elephant. I take you through a tour of the inside of this beast as well as give you a demo of the type of sound this instrument produces.

Note: weighed the unit after the video and it weighs in at 76lbs or 34.47Kg

Thanks for watching!

Sincerely,
Jareth"

"Here's a classic ARP 2600 / 3620 Keybed + Eventide FL201 Instant Flanger that were just restored by our shop! The FL201 paired up with the ARP 2600 is such a delight!

ARP 2600 restoration details:
-PSU Rebuilt
-Tantalum Capacitors changed
-Every Slide Potentiometer desoldered, disassembled, cleaned and re-greased (this is no small job, there are 55 sliders to rebuild!)
-Rebuilt entire 3620 key-bed including new rubber bushings, alignment of all keys/metal guides, cleaning of all gold contacts
-3620 rebuild of LHC. New Bourns sliders/adapters added for better reliability/functionality.
