Specializing in:

"Making studioclean“ of audio devices.

Tracing, shielding, compensation of inductive/capacitive hum field leakage.

Tracing and resolving of ground loops, internal and external.

Tracing and resolving of layout/wiring flaws which lead to signal contamination.

Where replacement of spare parts alone won’t suffice:

Upgrade repairs, flaw corrections, design and margin improvements,

which will lead to improved reliability and stable sound.

Where appropriate: In-depth fault analysis

Re-drawing of unavailable schematics from PCB.

I won’t probably be able to repair:

Devices that base largely upon SMD. Transmitters/Receivers.

Devices that manufacturers/importers won’t supply any schematics nor service manuals to.

DVD/BD-Player, cellphones, modern still/video cameras, mini-multimedia-player and ultracompact stuff.
