service & support

Conrad-Johnson audio components are built to last. There are thousands of conrad-johnson components now in service, many now decades old. And to keep those products operating as new, we continue to offer service on every preamplifier, power amplifier, and digital converter that we have ever built. Check here for information on our service policies.

If you have an older conrad-johnson product that you are fond of but want to enhance its performance to the next level, we also offer upgrades to circuits and to parts. If you are considering upgrading your conrad-johnson product, trust it to the people who know those products best – the conrad-johnson team of engineers and technicians. Check our web pages on model and circuit upgrades and on capacitor upgrades for more information and lists of available upgrades.
