Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.
Analogue Solutions is a British boutique electronic-instrument manufacturer founded and led by synthesizer designer Tom Carpenter. The company specializes in true analogue synthesizers, sequencers, modular/Eurorack systems, and related electronic music instruments, with products including the Leipzig, Impulse Command, Fusebox, Vostok, Nyborg, Polymath, Colossus and Maximus families. It is particularly known for deliberately traditional analogue design: analogue signal paths, analogue oscillators, filters, LFOs and envelope generators, minimal reliance on CPU control, and generally no patch-memory architecture. Analogue Solutions was also an early participant in the Eurorack modular-synth movement and emphasizes hand-built construction in England and a vintage-inspired sound and workflow.
Units may fail to power up, operate intermittently, or suffer internal power-stage damage from failed adapters, regulators, or incorrect AC/DC supplies. Many legacy Analogue Solutions models require AC adapters, and using an incorrect supply can prevent operation or potentially damage the unit.
VCOs may become unstable, fail to track octaves correctly, or drift excessively after warm-up. Aging calibration components, trimmers, temperature-sensitive circuitry, or oscillator components can make accurate tuning impossible.
Rotary potentiometers may become noisy, mechanically loose, erratic, or develop dead spots. This can cause abrupt changes in oscillator tuning, filter cutoff, modulation depth, envelope parameters, or sequencer voltages.
The synthesizer may stop responding to incoming MIDI notes, exhibit incorrect pitch conversion, or fail to trigger envelopes. Faults can originate in the MIDI input circuitry, optocoupler, MIDI-CV converter, DAC, connectors, or associated logic.
A unit may power normally but produce weak, intermittent, distorted, or no audio output. Common fault areas include the VCA, mixer stages, output amplifiers, jack contacts, filter path, or associated analogue circuitry.
Oberkorn, Megacity, Leipzig, Fusebox, Impulse Command, and related sequencer-equipped models may stop advancing, skip steps, fail to reset, or produce incorrect CV/gate outputs. Likely causes include worn switches, clock circuitry faults, step-control electronics, potentiometers, or output jack problems.
Patch, CV, gate, and audio sockets may become intermittent or lose connection from repeated insertion and mechanical stress. Failed or cracked solder joints around panel-mounted PCB sockets can cause missing signals or operation that changes when a cable is moved.
Toggle switches, rotary selectors, pushbuttons, and step controls can become intermittent or stop switching functions correctly. This may disable oscillator sync, waveform selection, sequencer steps, modulation routing, filter modes, or envelope triggering.
Oscillator or LFO signals may remain faintly audible when the VCA should be closed, producing background tones, clicks, or modulation bleed. Faults or calibration errors in the VCA, modulation routing, grounding, or surrounding analogue components can increase this leakage.
