Re: TLM193

Hello CM,

the schematic of the first TLM193s was part of the operating manual: https://www.neumann.com/download.php?dow nload=copi0013.PDF

But, it is very rare that IC2 fails. As shown in the schematic, IC2 (a dc/dc converter) should produce +10V and -52V. Only if these voltages are not produced should one think about exchanging IC2.

Sennheiser Canada will contact you in this matter.

Question: is the mic completely dead?

Best regards,
Martin Schneider / Neumann Mic. Development
