PREMIUM NPN MOJO: Set of 5 NOS Soviet MP37B (МП37Б) Germanium Transistors
If you are looking for the absolute peak of Soviet NPN germanium, this is it. These are the "B" (Б) graded variants of the legendary MP37. In the Soviet military grading system, the "B" suffix denotes the higher-performance, tighter-tolerance bracket specifically selected for critical audio and signal applications.
The NPN Advantage (Modern Board Friendly):
Forget dedicated positive-ground power supplies or noisy charge pumps. Because these are NPN, you can build a vintage-spec Fuzz Face, Tone Bender, or Rangemaster that runs perfectly on a standard 9V Center Negative power supply (Boss-style) right alongside your modern digital pedals.
Why the "B" Variant Matters:
While standard MP37s are great, the MP37B offers a more consistent, slightly higher gain profile and an incredibly low noise floor. They provide that creamy, harmonically rich "glassy" clipping that germanium is famous for, with the stability of a military-grade component.
The Details:
Quantity: 5 Transistors (Perfect for a 2 or 3-transistor build + spares for matching).
Part: MP37B (МП37Б) NPN Germanium.
Condition: NOS (New Old Stock) – Vintage, untouched, never soldered.
Tone Profile: Smooth high-end, excellent cleanup with guitar volume, and very low leakage.
USA SELLER: Don't wait 4 weeks for an international shipment to maybe show up. These are in stock and ship fast and securely from Illinois, USA.
