The focus has always been the same:
understanding how things work – and making them work again.
This practical experience shapes everything in the shop.
Every product, component, and solution is chosen with real usage in mind.
The goal is not just to sell parts –
but to support builders, makers, and technicians who enjoy working with electronics.
Asplund Circuits is an independent electronics brand focused on high-quality components, restored hardware, and custom-built solutions for both audio and arcade applications.
The shop was created to serve two communities that share the same foundation:

From Eurorack modular synthesizers to pinball machine restoration, Asplund Circuits provides carefully selected components and parts that are suitable for real-world use – not just catalog listings.

to provide components and products we would trust in our own builds.
