Quad Tube Amp Bias Tester 6l6 El34 Kt88 6v6 6bq5 7591:
BE A SMART CONSUMER
DO NOT LET OTHER SELLER MISLEAD YOU.
The reading shown on the bias is in current (ma) which is better than those show reading in voltage (it does not need to convert from voltage to current. )
So far, over 500 of this item have been sold andno onecomplains about the accuracy of it.
You should make a clever choice.
You are offerding on aQuad amp tube biasTester withone pair (2pcs.) Normal type probe cables only. (It is detachable). You have an option to purchasea pairSpecial type 8-pins probe cables( for 7591,7591a.7355 )or 9-pins probe cables For EL84, 6BQ5,7189 .
The price $30.00 for a pair 9-pins probe cables.( EL84 ,6BQ5,7189 )
The price $30.00 for special type8-pins probe cables.( 7591 ,7591A.7455 )

For the future, you can use thisTester for other type tube probe cables.
you can get the reading direct from the current meter. It does not need any convert from mV to mA. It can be work with all kinds of multi meter (Digital meter or analog pointer meters) , at range of 100mA or above.
It is a safe, risk free meter, it measures the cathode current
of the power tube for bias reading (at low voltage side of the tubes ).
Steps to check the bias of your amplifier:
This procedure should not take more than 15-20 minutes.
