I do repairs of all audio electronics: guitar/bass pedals, amplifiers (solid-state or tube amps), guitar electronics, power supplies,... I love doing restorations of old tube equipment like radios and amplifiers, solid-state hifi amps (Sansui, Pioneer,...) and such.

I charge 10 euros (VAT excl.) per 15 minutes of work, plus expenses for any replacement parts. 

Repair costs primarily depend on the amount of time it takes to perform a decent diagnosis and the actual repair. In general:

- PCB’s or printed circuit boards are harder to work on than point-to-point wired circuitry. PCB's are rather fragile and packed full with components, and often quite tricky to remove in order to perform the repair. In short, it takes more time. 

- Old vintage equipment that has never been revised before, often contains a number of worn-out components. Some components have a limited lifespan. A 1960's tube amplifier will very likely contain dried out or DC-leaking capacitors, possibly also noisy resistors and potentiometers, and so on. While 'vintage' is a good marketing label, it does usually mean the device needs a lot of tender loving care. 

I only use quality components with a more than acceptable lifespan (Nichicon, Panasonic, Vishay,...) and no shady brands.

Feel free to contact me if you have questions.
