Included in this kit are the semiconductors needed to complete an Aleph J amplifier, with the exception of the input JFETs, which can be sourced separately through the store. MOSFETs were matched in accordance with standard operating conditions. This is enough transistors for 2 channels (one stereo amplifier).

Good supplier, but some problems with matching IRF240 currents

All the devices worked. I measured the Vgs of the IRF240 and they were well matched between 3.45V and 3.49V. However, not sure about the transconductance as near equal drain currents did not a result with the Aleph J even though the source resistors were close tolerance. By trying varying combinations I eventually matched currents within 5%. Very pleased with the Aleph J performance.

Great Amp

Responsive staff, great board, great kit and very great amp. Thanks

Aleph J Transistor Kit

Professionally packed and well protected for delivery. I Intend to continue doing business with diyAudio. Great products and service.

Aleph J transistor kit

Thank you very much diyAudio store! Almost all the transistors needed for the Aleph J. If i can i give 6 stars just because the devices are already matched, so beautiful to have the transistors this way.
