Classic Valve Design
Custom amplifier and preamp designs are what we specialize in. We have proven time again at audio festivals that there is more to great audio than meteor shattering levels of power that modern home theatre amplifiers can deliver.

An audio system is like a well fitting suit, you shine best when the pieces match or have been tailored to your needs.

We also do upgrades and modifications of most existing Hi-Fi equipment. Custom gear from other boutique manufacturers like Yanqin and modern staples such as Antique Sound labs, Opera and Rogue. Vintage amplifiers like Dynaco, McIntosh, Marantz, Sansui, Pioneer, Acoustat and many more!

We also have experience re-tubing, repairing and modifying many brands of guitar amplifiers, including Traynor, Fender, Peavey, Marshall and countless store-brands.

Don't hesitate to contact us for an honest assessment and estimate regarding a custom build or modification. Tube audio is more affordable than you may think!
