Hi guys,
Yet again, I have purchased another microphone from Ebay which is not 100% working. It is the same model, a "Thiele M4" which Cedric mentioned recently.
The problem starts with the fact that the internal power supply has been removed. This has obviously been done to reduce noise - other members here said that this was a major problem with this mic.
I was read about this mic (maybe on the old board) but can't find much info.
So, anyway, I have posted two photos of the insides of the mic below. In the lower part of the mic, there would originally have been a power transformer with a mains cable.
Now I am wondering what should I do with it?
My G7 boards look a little bit long - the board would fit from the bottom of the case all the way to the bottom edge of the capsule.
With a G7 board, the valve could be moved from behind the capsule and it would maybe be quite nice.
At the moment, there is a cable with 6 pins which should be connected to a power supply which I don't have. I'm not sure what parts of the original power supply are still in the microphone - maybe some smoothing caps and a few resistors, but I'm not sure.
I'm willing to do anything to get it going, although I'm not sure how easy it would be to trace out a schematic of the remains of the circuit.
So, do any of you have any suggestions for what I should do with it?
Cheers,
Roddy
