Wanted Bias Meter for valve amplifier
Looking for a Bias meter for a valve amplifier to adjust and set when required
have looked at a decent multi-meter (Fluke) but seem overkill for this. Also considered the cheapo Chinese metres but advised they can be unreliable and inaccurate:scratch:
Suggestions and offers appreciated
*** Cheapo Chinese multi-meters... WARNING, BUYER BEWARE!!!!! ***
F.A.O Malcolm (the OP) and all other members,
I have it on good authority from another one of our members, who is also a qualified electrical engineer, but who doesn't wish to be named on the thread, that these cheap unbranded multi-meters are dangerous, as he has had experience with them and has seen the evidence for himself of how dangerous they can be!!
The danger is that if the OP, or anyone else decides to test mains voltage with it, then there could be a major Arc Flash incident, resulting in possible burns and eye damage, due to UV radiation generated. Apparently these metres have been subject to no CE testing or approval, and that any indication to the contrary, it is liable to be fake!
I cannot comment, as I've never used one. I'm simply passing on a message from someone who's knowledge and experience I trust. Therefore, PLEASE CONSIDER THE ABOVE WARNING VERY CAREFULLY before thinking about buying one of these items.
Marco.
