"In this video I get my hands on a nice KORG KR55 drum machine
I love the sound of this machine. The kick and snare especially.

ROLAND JUNO 6 - LFO TRIG BUTTON REPAIR AND BASIC CALIBRATION

video upload by Mindburner

"This Roland Juno 6 was mostly working well but had a small but annoying problem in that the LFO Trig button was not working.

Power supply capacitors were changed and the machine calibrated.
Some other small issues corrected.
Apologies for the tedious trimming shenanigans.

OSCAR SYNTHESIZER - FITTING THE TAUNTEK MIDI BOARD AND OPERATING SYSTEM

video by Mindburner

"The OSCar is a fabulous monosynth designed and built by Chris Huggett. My machine had been plagued with issues from day one. A major problem was the highly unreliable start up. The synth would not 'boot' and many power off/on cycles were needed to get it to work.

TAUNTEK have a new MIDI PCB and Operating System with may new features. I hoped this may fix my synth and make it useable aging. Here I detail my install of one of the first version of the Firmware.

The PCB needs to be built but many of the parts are readily found.

More details can be found at TAUNTEK
Special thanks to the folks on the OSCar freelists group.

Video for information only. A qualified synth tech is always recommended for synth repair."

Inside VINTAGE SOVIET ERA ESTRADIN 230 - FIXING AN OSCILLATOR AND OTHER REPAIRS

Mindburner

"In this video I repair a failed Oscillator on an Soviet era Estradin 230 monosynth.
Built in or around 1983 at Elektroizmeritel planet of Zhitomir, this synth is roughly a Minimoog clone, although in reality it has a different character, being more raw and rough.

3 Oscillators
Has A440
Filter and Envelop controls

KT140UD7 was the faulty opamp, replaced with a 741"

TEISCO 60F MONO SYNTH - ADDING A D.I.Y. SUB OSCILLATOR

Mindburner

"I love my 60f, most owners do. The low end already is great, I though it could be improved though with mod, a sub oscillator.

Here I use a CD4024 IC and a simple circuit. The circuit is available on the net. Google mod for JEN SX1000 and the circuit is the same.

Parts Used:
CD4024 IC
14 pin socket FOR 4024
47k resistor
100k resistor
500k lin pot (with switch - or use additional switch)

The 2 resistors shown at the end of the video (5:32) on the sub oscillator board were not actually used. These were from a previous mod, and I just repurposed the board.

The stills at the end (5:41) show signal out from the synth and signal in to the synth

Please note - I cannot guarantee results if you chose to mod your own synth. This video is for information only and is my own personal experience and not binding"
