Gyraf Audio

audio machinery, using electronics technology mostly originating around 1950. Note that we're not purists - we use modern solid-state electronics for non-audio purposes - like power supplies, metering, and side-chains and so forth, as well as for the "Active/SolidState" signal paths selectable in some of our designs. Likewise, the G21 "Magneto-Dynamic Infundibulum" contains a variety of semiconductor rectification elements in signal path, but these are used entirely in passive mode. Manufacturing:

In manufacturing, we (I) hand-build every single unit. Mass-production makes little sense for our type of designs, relying on massive amounts of careful matching and selection of components. Product range:

Our product range covers a broad range of equipment intended for Recording and Mastering. Tubes, NOS, and the future:

In our products, We have so far only used NOS (New Old Stock) tubes of the highest quality, but still we base all our designs on readily available tubes, most of which are in current production - because it's important to know that availability of spare tubes is not going to be a problem anytime soon..
