Spark Gap V-Type

This is the improved version of the V-type quenched spark gap used in the original Lakhovsky Multiple Wave Oscillator Models BV1 and BV2.

Technical Specifications

Four simultaneously adjustable spark gaps consisting of 3.4 mm diameter, 30 mm length wolfram (tungsten) electrodes. The spark gap performance is improved with forced air cooling (fans).

Dimensions (L x W x H)
200 x 220 x 60 mm

2.4 kg


The original design was modified in several ways:

  • Improved threaded mechanism ensures smoother movement and low wear of the material.
  • Added PTFE (teflon) layering to prevent possible charring and short circuits on the textolite (bakelite) based parts.
  • Tungsten electrodes diameter is commonly used 3.4 mm (easy to find in welding shops).
  • Electrode holders and their placement allow easy replacement of electrodes (disassembling is not required).
