Hello Mr Belov,
thank you for your request. There are two possibilties to repair your UM70:
1) Replacing the damaged sound transducer by a new soun dtransducer STW7.1. We offer it with two different kinds of material: STW7.1 blue line (diaphragms made of PVC) and STW7.1 red line (MCF/mylar). The STW7.1 blue line is about 275 EUR, STW7.1 red line is about 247,50 EUR.
2) Reskinning /repairing of the existing sound transducer. We can give new diaphragms to it. A reskinning with red line material (MCF/mylar) is about 107 EUR with blue line material (PVC) it is about 129 EUR. Additional there will be 11 EUR for assembly if you like to send the whole mic head.
In both possibilities we won't use these original black or grey plastic rings. We use a red or blue tape around the diameter of sound transducer as you can see at:
http://thiersch-mic.de/en/estm_produkte.html (STW7 and STW7.1). Or do you think of another plastic ring?
Please feel free to ask,
best regards
Jessica Vetterlein
