It works like it should

It's a volt meter, what can I say? Connect the cables, turn it on, it displays what it should. Only gripe maybe is that it's plastic but it's not like you need to carry it around on tour.

Great thing to have to avoid your amp sitting in someone's shop for weeks. With this biasing your amp takes under half an hour total.

TAD Bias Master BM4

This model comes with 4 octal probes, but I ordered 2 noval probes as well so that I can set up EL84's as well as 6V6's and 6L6's etc.
WARNING! - There are no instructions! - If you don't know what you are doing, don't try to use this unless you have a friendly tech to show you. You can download them from the TAD site, only 2 sides of A4 folded into a leaflet. Very basic instructions.
The probes each contain a 1 ohm resistor in the cathode lead, so they are measuring total cathode current (anode + screen grid). Circuit schematic diagrams usually state a bias Voltage (e.g. -37Volts) rather than current. This is a good starting point, but then you need to find the valve manufacturer's specifications from their data sheets. Then you can balance up each side of the push-pull stage.
The readout on the unit is 00.0 mA to presumably 99.9 mA.
A "Chicken head" pointer knob selects each of the 4 individual valves, or the OFF position.
It's really simple and easy to use (as another reviewer has said) and you don't have any high voltage connections to make through a test meter. The real skill is knowing just where to set the current level, which is of course different for each and every valve type and can be slightly tweaked for your preferred sound.

It`s okay
Amateur Slash 27.05.2017
Unfortunatelly there aren?t too many options on the markt to choose from.
Would have preferred a tool that can measure the plate voltage too.
It does though what it says in it?s title therefore i?m quiet satisfied with this product.
Quality of the material has a bit of a cheap expression.
Color coding or numbering would have been preferable for the cables.

The Probes are prone to break

Otherwise good but I've had already 2 pair of busted probes.
