Nyal Julius Futterman OTL-2B // Vintage / Stereo Tube Amplifier / Restored And Super Rare

Dive into the legacy of Julius Futterman, the inventor of the legendary OTL (Output Transformer-Less) tube amplifier topology, brought to commercial life by New York Audio Labs (NYAL). The OTL‑2B is a rarer, lower-powered (10wpc) sibling in that iconic lineage—an electrifying slice of hi-fi history. The OTL‑2B is far rarer than the flagship OTL‑1, with Japanese-market variants offering about 10 watts—delicate but captivating in smaller systems.

Fast, airy dynamics with a wide bandwidth (up to 250 kHz in some models), delivering crisp attack and bloom .

Low impedance coupling means excellent control over reactive or challenging speakers—electrostats, ribbons, oddball vintage cabs welcomed

Natural tonality: smooth mids, detailed highs, and no transformer coloration—just pure, direct tube sound.

This piece has a few small nicks and scratches, but is remarkably clean.

Packing

Prepare to be impressed. We have arguably the best packing process around. We use our InstaPak machine and white open cell foam to build a custom enclosure for your piece that ensures that it's stable and secure. If it is particularly fragile or heavy, we typically opt for private courier delivery. Depending on where you are in the country, that may cost a bit extra. We also take great care to protect the tubes. When sensible, we will pack the tubes to prevent any movement. Other times, we'll individually wrap the tubes and mark their corresponding socket to preserve the bias. You can be confident that your piece will be snug as a bug in a rug.

Shipping

This piece ships to the contiguous United States for a flat rate of $150, which includes our packaging and our insurance. Of course, we'll ship anywhere in the world, just drop us a line and we'll give you an estimate – even if you're just curious.
