The VU meter is also sticky , tends to get stuck either at the upper or lower end of the scale , any ideas on freeing it up welcome . Ive emailed the manufacturer to try and get the schematic/manual . Seems like a good quality gold plated membrane in the capsule , might be usable for recording even if the meter doesnt work .
I managed to free up the vu meter by adjusting the pivot bearing , less than a quarter turn out was sufficient to stop it from binding , I have audio at the output , but still no deflection on the meter . 4mm bananna plugs for output signal , I'll rig up a cable tomorrow and give it a listen . It doesnt have the hefty build quality of the Bruel &Kjaer 2203 ,but it is still a high quality instrument , runs off a single 1.5v A cell .
