Vacuum Tube Accessories

Tube adapters have many applications; allowing use of less expensive tube types, changing the tone of your amp or for use as a socket saver.
Keyway - Replacement piece for octal tubes
Package of 4
Do you have valuable octal type tubes that work fine except the keyway has been broken off the base? Fix it with this simple and inexpensive product. Simply clean the remainder of the broken keyway from the base and slip one of these on. Will stay on by itself, or you can use a dab of silicon to attach if you wish.

Solid State Rectifier - Yellow Jackets® YJR, For 5AR4, 5U4, 5Y3
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. The tube rectifier can easily be swapped back in when sag is desired. This Yellow Jacket® is a solid state device and as such does not come with vacuum tubes.
• Converts most audio amplifiers which use a vacuum tube rectifier 5AR4/GZ34, 5U4 or 5Y3 to a solid state device.
• Safe for all common amplifiers and transformers.

All Yellow Jackets® have a one year warranty against manufacturer defects.

Tube Converter - Yellow Jackets®, YJS
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). All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.

Tube Converter - Yellow Jackets®, YJShort
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. All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.

Tube Converter - Yellow Jackets®, YJC
The YJC is similar to the YJS, but for use in amps with cathode-biased power tubes. Cathode-biased power tubes have a bias resistor connected from their cathode to ground. The ground wire of the YJC is used to bypass the amp’s cathode bias components so the Yellow Jacket® converter’s internal bias components are used instead. All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.

Tube Converter - Yellow Jackets®, YJ20
The YJ20 is for use in most amplifiers using 6V6 output tubes. The YJ20 is similar to the YJC but does not drop the plate and screen voltages. It is meant for use in lower power output amps (20 watts or less) when no power reduction is desired. The ground wire connects to the chassis-ground for cathode-biased amplifiers. All Yellow Jackets® converters come with JJ Brand EL84/6BQ5 vacuum tubes.

Tube Converter - Yellow Jackets®, YJ7591
The YJ7591 is a specialized, current-limiting/voltage-conditioning adapter for use in most amplifiers that use 7591 output tubes. Only the triode version will provide a noticeable power reduction.
