Want to hear what your headphones sound like when directly connected to the tubes? Are you also a bit crazy and heat-tolerant? Then Folkvangr—our completely bonkers, limited-production, 10-tube OTL/OCL tube amp with impedance multiplier—may be for you.
Connect Directly to the Tubes
Folkvangr goes beyond output transformerless tube amps, and also eliminates the output coupling capacitor. With Folkvangr, your headphones are literally connected directly to eight 6N6P output tubes, with nothing at all in-between. An advanced 8-servo DC stabilization system with DC sensing and relay protection ensures the safety of your headphones.
Change Your Lows to Highs
Tubes will never be the equal of transistors with low impedance loads, so we added a switchable, integrated impedance multiplier that makes your low-impedance headphones look like high-impedance headphones. Switch on the multiplier, and your 32 ohm headphones look like 256 ohms to the amp, so you can use a wider variety of headphones.
Roll, Switch, Connect, and More
With Folkvangr, you can “roll” the 6N1P input tubes for 6922, ECC88, and many other tube types, so you’re assured of a wide variety of options. Choose low or high gain, switch between two inputs, and connect to the provided preamp outputs to create an entire system.
Designed and Built in California
By “designed and built in California" this is what we mean: the vast majority of the total production cost of Folkvangr—chassis, boards, transformers, assembly, etc—goes to US companies manufacturing in the US. Our chassis are made minutes from our facility. Our PCBs are done just over the hill from us. Our transformers are also made in California. You get the picture.
