High quality W22 resistors from Welwyn / TT Electronics W20 Series. These 7W wirewound resistors are a great choice for screen grid and cathode bias resistors in tube amplifiers. The brown enamel coating used by Welyn looks great in vintage and vintage-style amps. These resistors can be found in many vintage Marshall amplifiers. A high purity ceramic substrate is assembled with interference fit end caps to which are welded the termination wires.

Solid State Rectifier Direct plug-in replacement for 5AR4, 5U4 and 5Y3 rectifier vacuum tubes in amplifiers with center tapped secondary power transformer. Use when less 'sag' is desired in the power supply; just switch back to the tube rectifier when 'sag' is desired.
$9.95

The YJR is a direct plug-in replacement adapter for use in most amplifiers that use 5AR4/GZ34, 5U4, 5Y3 or similar full-wave rectifier tubes. The YJR converts your amp's vacuum tube rectifier to a solid state rectifier, reducing tube sag for a tighter sound and feel.
