    The “Fox 460” circuit is a massively upgraded CCDA topology, including a selected 6072 tube, custom-wound transformer, and a third-generation circuit made with the best parts on the market.

    The “V-251” circuit is a single triode design with a T14 transformer.

Multi-Pattern Tube Condenser Microphone

The TCM-1150 is a variable-pattern, dual-diaphragm, large diaphragm tube condenser mic that is a favorite starting point for mic modders.

It is manufactured in China, although as with all outsourced manufacturing it is impossible to state specifically which factory might have produced the mic at any time. Indeed, it is likely the supplier has changed since the mic’s introduction, and maybe for each production run.

The mic uses a 6072/12AT7 tube, a 1-inch diaphragm that is almost certainly a Chinese-made K67-style (center-terminated, dual-diaphragm) capsule, and a 9-way pattern selection switch on the power supply.

The Nady TCM1150 is also known as: TCM-1150.
