Yellow Jacket Tube Converters
Yellow Jacket® tube converters allow EL84 power tubes to be used in place of the most common guitar amp power tubes, including 6L6, EL34, 6V6, 7027, 6550, and 7591. Most Yellow Jacket® converters provide a substantial output power reduction and a "self-bias" Class A configuration for the EL84 so that no bias adjustment is required. Yellow Jacket® converters are like getting a whole new amp.
The YJC is a specialized, current-limiting/voltage-conditioning adapter for use in most 20 to 100 watt amps that use 6L6, EL34, 6550 or 6V6 output tubes. The YJC is for use in amps with cathode-biased power tubes.

The YJShort is shorter than the standard YJS converter, allowing for use in amps that do not have room for the standard converters. It is a specialized, current-limiting/voltage-conditioning adapter for use in most 20 to 100 watt amps which use 6L6, EL34, 6550 or 6V6 output tubes

The YJS is a specialized, current-limiting/voltage-conditioning adapter for use in most 20 to 100 watt amps that use 6L6, EL34, 6550 or 6V6 output tubes. The YJS is for amps with fixed bias power tubes. (Fixed bias tubes have their cathode connected directly to ground and a negative DC voltage applied to their control grid).

The YJUni is a simple pin-converting adapter for use in most amps with 6V6 or similar based tubes like 6F6, 6G6, 6K6, 6Y6, etc. The YJUni is shorter than standard Yellow Jacket® converters. It is designed for use in lower power output amps (20 watts or less) when no power reduction is desired.
$29.95
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.
