Description
This TM-1 has been modified with a lot of upgrades. I purchased the microphone new around 2010 and it has been used at LBA Studios since. During my ownership of this mic I performed a number of modifications to it in order to achieve a lower noise floor and what I consider to be a better sound than stock. See the full description off to the side for details.
This TM-1 has been modified with a lot of upgrades. I purchased the microphone new around 2010 and it has been used at LBA Studios since. During my ownership of this mic I performed a number of modifications to it in order to achieve a lower noise floor and what I consider to be a better sound than stock. Listed below are all of the things I've done to it.
- The capsule has been replaced with a Peluso P-K47.
- The Mitsubishi vacuum tube it came with has been replaced with a much-coveted Telefunken tube.
- The tube socket has been isolated from the rest of the microphone with a spring loaded suspension mount in order to reduce microphonic noise.
- A -10dB pad was added to the front of the mic. It came stock with a high frequency roll-off switch and an Omni/Cardioid switch.
- All capacitors in the mic and power supply were replaced with higher quality capacitors.
- The AC wiring in the power supply was rewired to be twisted pairs for better noise rejection.
- The IEC power socket was replaced with a higher quality gold-plated socket.
- A ground noise filter was added to the power supply.
- A tube damper was added to the vacuum tube to further reduce microphonic noise (not pictured).
- The power supply
- The original hard-shell case
- A key for the locks on the case
- The original microphone suspension/shock mount
- The original 7-pin XLR cable that connects between the microphone and the power supply
- An IEC power cable suitable for North America
