Revisit™ BiasEasy800
The Bias Easy™ 800 measures the current in the power tubes of your amp. Includes two 8-pin probes with gold plated pins and socket, power adapter and  operating instructions.  Fully assembled and ready to use.  For 8-pin power tubes such as 6L6, 6V6, 5881, 6550, EL34, KT88, KT66, KT100, etc.   Not for 7591 tubes (see below for special probes for the 7591 tubes).

The Bias Easy™ 800 allows you to monitor the bias setting safely and easily. While adjusting the bias control pot of your amp, the Bias Easy™ shows the actual current flowing through each of two power tubes.   A switch on the meter allows you to go back and forth between the two tubes.  This lets you set and evaluate the full reasonable biasing range your amp and tubes offer so that you may find the perfect setting.  Complete instructions are included.

We also include "quick-start" instructions so that you can start using your new Bias-Easy right away!  See the quick-start instructions here.

The bias setting has a dramatic impact on the amp's tone, response, break-up and dynamic character.

Revisit™ BiasEasy800 and 1200 Probe Set for 7591 and 7591A Tubes
As noted, the Bias Easy™ 800 and 1200 models with standard probes cannot measure the bias current in 7591/7591A power tubes, due to a difference in the pin assignment (cathode on pin 5 instead of the usual pin 8).  With the RBE-7591-PROBE SET, you can now use the Bias Easy™ 800 and 1200 units to measure the current in 7591 type tubes power tubes, and properly set their bias.

Very few bias meters offer a 7591/7591A tube option.

Includes two 8-pin probes with gold plated pins and socket.  FOR USE WITH 7591 TUBES ONLY!   These probes are clearly marked '7591'.

A short list of a few amplifiers which used 7591 tubes in the output section:   Ampeg J12R Reverbojet, Gibson GA35RVT Lancer, Premier Twin 8 (1961 through 1964 models), Hammond E and H series organs (including the H-100, H-200 and H-300), Leslie models 122 and 142, as well as others.   New replacement 7591 tubes are still being manufactured for these amplifiers, and are available from both Electo-Harmonix and JJ Tubes.

The bias setting has a dramatic impact on the amp's tone, response, break-up and dynamic character.

    1 INCH CHIP BRUSH
    Chip brushes are very similar to a paint brush. The difference is, paint brushes may use bristles that will melt when in contact with certain solvents and are expensive (for the good ones anyway).  This is where chip brushes shine.   Chip brushes are made with natural China bristles that will hold up to flux, epoxy, glue, resin, stain, paint remover, solvents, cleaners, oils and more.  

    They also make a great dry duster to use in cleaning dust, spider webs, etc from the insides of amplifiers.

    Chip brushes have a wood handle so they are firm and comfortable to use.    The best part, they cost much less than paint brushes so you can use them to apply sticky, nasty and harsh adhesives or even use them in a parts cleaner with solvent and when you are done with them, toss it out.    Bristles are 1 inch wide, total length of brush is 7 1/4 inches.

    OCTAL TUBE KEYWAY, SET OF 2
    If you have a cherished octal power tube, rectifier, or bias probe with a broken keyway, here is a great solution. By cleaning the remainder of the broken keyway from the tube base and properly installing this keyway replacement (a little dab of silicone sealant works great to hold it in place), your tube can safely be reinstalled into your equipment.   These great tube-savers are sold in sets of 2.   Note:  When using an adhesive to secure the keyway to the tube base, DO NOT use a water-based glue.   Silicone sealant (RTV) which is acryllic-based or butyl-based is fine.   Latex sealant or hot-glue is NOT.
