Hi Guys,
Please help me here. I have a Marshall JCM 2000 TSL combo. Now I must say up front that I'm not an electronics fundi, but I want to be able to do simple tasks like re-bias the amp when changing valves etc. I've googled how to bias this amp, and it seems to be a pretty easy process that I'm sure I could manage if I had a multimeter. There's a plug on the back of the amp that you connect the multimeter to and you bias to a setting of 80mV according to Marshall.
Therein lies the problem. I've been trying to find a multimeter to buy so that I can do this when I need to, which won't be very often, but the only multimeters I've managed to find that had 80mV within their measureable range cost over R3k, which just seems to be silly money to spend on something I'm otherwise hardly going to use.
Is this the norm, or do any of you know where I could get a multimeter that would be able to measure down to say 50mV that doesn't cost more than a couple of hundred rand?
Thanks in advance,
Shaun
