Product code: Classic Pass Labs Aleph Amplifier PCB and Kits hotsell

Up for sale are PCB and active parts kits for the Classic Aleph amplifier. These are based on the famous Pass Labs Aleph amplifiers, and this project was blessed by Nelson Pass for a Group Buy on DIY Audio. These boards are left over from the recent DIYAudio Group Buy offering. The boards have been used to make the following:
Aleph 30 Stereo (30 Watts Per Channel - Class A into 8 Ohms)
Aleph 30 Monoblocks (30 Watts Per Channel - Class A into 8 Ohms)
Aleph 60 Monoblocks (60 Watts Per Channel - Class A into 8 Ohms)
Aleph 2 Monoblocks (100 Watts Per Channel - Class A into 8 Ohms)

The concept for this project was:
Build a Classic Aleph circuit on a PCB for DIYAudio Chassis UMS heatsinks
Make it Flexible / Expandable - the "Swiss Knife Aleph". Include the ability to add additional PCB(s) for more semis. Want an Aleph 3/30? How about a 5/60? Got enough heatsinks for an Aleph 2?

Detailed Bill of Materials, schematics, and build details are located in build guide documents. The build guide documents and "Builder's Thread" are located here:
https://www.diyaudio.com/community/threads/classic-aleph-amplifier-for-modern-ums-chassis-builders-thread.382316/

The boards are purple with 2oz copper and gold ENIG finish. The exception is the A/C Cap & CL-60 Board, which is HASL finish.

Aleph 30 Stereo Kit includes:
Qty. 2 - Classic Aleph Main PCBs
Qty. 1 - "New Original" F5 Power Supply PCB
Qty. 2 - Rectifier / Snubber PCBs
Qty. 12 - Precision matched Vishay IRFP240 MOSFETs
Qty. 6 - Precision matched Harris/Fairchild SFP9610 MOSFETs
Qty. 4 - ZTX450 or 2N4401 NPN Transistors (NOTE: Pinout is reverse on 2N4410, and it will be installed opposite to the shape on the PCBs)

Aleph 30 Monoblock Kit includes:
Qty. 2 - Classic Aleph Main PCBs
Qty. 2 - V8 CRCRC Supply PCBs
Qty. 4 - Rectifier / Snubber PCBs
Qty. 2 - A/C Cap & CL-60 PCBs
Qty. 12 - Precision matched Vishay IRFP240 MOSFETs
Qty. 6 - Precision matched Harris/Fairchild SFP9610 MOSFETs
Qty. 4 - ZTX450 or 2N4401 NPN Transistors (NOTE: Pinout is reverse on 2N4410, and it will be installed opposite to the shape on the PCBs)

Aleph 60 / 2 Monoblock Kit includes:
Qty. 2 - Classic Aleph Main PCBs
Qty. 2 - Aleph Expansion PCBs
Qty. 2 - V8 CRCRC Supply PCBs
Qty. 4 - Rectifier / Snubber PCBs
Qty. 2 - A/C Cap & CL-60 PCBs
Qty. 24 - Precision matched Vishay IRFP240 MOSFETs
Qty. 6 - Precision matched Harris/Fairchild SFP9610 MOSFETs
Qty. 4 - ZTX450 or 2N4401 NPN Transistors hotsell (NOTE: Pinout is reverse on 2N4410, and it will be installed opposite to the shape on the PCBs)

NOTE: ZTX450's have been out of stock globally for roughly one year. The 2N4410 can take the place of the ZTX450, but the pinout is the opposite. The 2N4410 will be installed opposite to the shape on the PCBs.
