The power MOSFET used in the Nady PMX-420 is the IRFP260N. It is a 300-volt, 100-amp N-channel MOSFET that is designed for audio power amplifiers. It has a low gate threshold voltage of 2.5 volts, which makes it easy to drive. It also has a high switching frequency of 1 MHz, which makes it suitable for high-performance audio applications.
The IRFP260N is a popular MOSFET for audio power amplifiers because it offers a good balance of performance and price. It is also available in a TO-220 package, which makes it easy to mount on a heat sink.
Here are the specifications of the IRFP260N:
Voltage rating: 300 volts
Current rating: 100 amps
Gate threshold voltage: 2.5 volts
Switching frequency: 1 MHz
Package: TO-220
If you are looking to replace the power MOSFET in your Nady PMX-420, the IRFP260N is a good option. It is a reliable and high-performance MOSFET that is well-suited for audio power amplifiers.
Here are some tips for replacing the power MOSFET in your Nady PMX-420:
Make sure that the power is turned off before you start working on the amplifier.
Use a heat sink to dissipate the heat from the MOSFET.
Secure the MOSFET in place with a bolt and nut.
Apply a small amount of heat sink compound to the MOSFET to improve heat transfer.
If you are not comfortable replacing the power MOSFET yourself, you should take the amplifier to a qualified technician.
