I'm curious, how do you know that your information is correct? I looked at the manual and there's nothing about bias values in there... Should I contact Marshall company (customer service) for their recommended bias value?
Do you bias it with the valves on? And what part of the amp do you place the multimeter at? I’ve never biased an amp, I’m not doing it but I’d like to know. Thank you so much
On CN32, is one common and the other VDC? I assumed the one with no run was the gnd and the other with the run the TP, but I couldn't get any readings on my DMM. Can someone help?
Same question. Although I didn’t quite understand the latter half of the same. The CN32 has 2 points, one is squared off and the other a round one. So using a multimeter, how do I calculate the bias? I have never biased an amp but am fairly confident on doing it but don’t know how. Though I just have a multimeter with 2 straight probes and not the ones I can stick tubes on so can someone help?
Hi Dennis You'll see the meter on the bench below the amp. It's a standard bias meter which you insert between the valve and its base. You can buy one from Eurotubes.
