Classic Pass Labs Aleph 30 Stereo Amplifier PCB and MOSFET Kit

Description: Classic Pass Labs Aleph 30 Stereo Amplifier PCB and MOSFET Kit. 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 heatsinksMake 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 PCBsQty. 1 - "New Original" F5 Power Supply PCBQty. 2 - Rectifier / Snubber PCBsQty. 12 - Precision matched Vishay or Fairchild IRFP240 MOSFETsQty. 6 - Precision matched Harris/Fairchild SFP9610 MOSFETsQty. 4 - ZTX450 or 2N4401 NPN Transistors.
