| [#1] PASS DIY 同好會 Very thanks to bro. dd845 to invite me to start this thread for PASS DIYers. "PASS DIY" was a name by Nelson Pass who owns Pass Labs (for high end consumer products), First Watt (all hand made by Nelson Pass with limited production) and PASS DIY (a DIY web page hosted by Nelson Pass to share his Class A design/circuit with all diyers). I have a chance to build his Pass Pearl phono and Zen V5 power amp.. For design/circuit stories pls. see his DIY homepage as below. http://passdiy.com/projects/pearlono1.htm http://passdiy.com/amps.htm Attached photos are my Pass Zen V5 and Pass Pearl Phono Kits (issued by DZ years ago).  |

| [#11] PASS DIY 同好會 timtube 兄, This is the first Zen power amp., a constant current source design, not tube amp.. Since the availablity of high power resistor for constant current source are limited and thus Nelson Pass use lamp bulb to replace power resistor and make this classical power amp., namely Zen-lightenment. |

I think this amp also has tube sound. |

| [#15] PASS DIY 同好會 Vash, I'm no diyer myself, so I really hesitate to speak on this forum. Yet to be able to learn more about circuits from diyers has always been my aspiration. You must be one dedicated Nelson Pass follower to be able to answer tim's challenging riddle. :-) |
