Chapter 1: History of the thread

[Post #5] - Our main man Jan then stepped up to the plate and said “I can make the PCB-layout”.

[Post #7] - Luke sorta requested the board be single sided and Jan in [Post #9] agreed that it would be easier for DIY’ers to make their own if it were.

[Post #31] - Jan publishes his schematic for thread review, quick work in my opinion.

[Post #38] - Pavel suggested and Jan agreed that the project remain a Krell Klone and not be an “improved version”.

[Post # 55] - Jan requests last minute updates before making the PCB layout.

[Post #264] - Rabstg has taken on a group buy for the boards designed by Jan, and posts preliminary information on the boards.

[Post #399-400] A Krell [Group Buy #1 (Jan's Boards) Wiki] is created, edited, and eventually by 14 January 2005, 112 boards are ordered.

[Post #403] Jan, designer of the 1st PCB board set, posts the following remarks:
Turns out to be quite the understatement.

[Post #690] The PCB Boards from the first group buy are shipped.

[Mike W's KSA 50] is posted in a separate thread March 3, 2005.

[Post #1848] Stuart gets a new girlfriend (congrats!) but more importantly (for us) begins work on a very high power version of the Krell clone.

[Post #1859] NUTTR realizes that the Krell clone is heating up his room by quite a bit.

[Post #1860] Stuart posts a pic of his basic output stage.

[Post #1875] Stuart has a bunch of non-inductive output resistors and people start buying them from him.

[Post #3502] Terry's amp is up and running. Looks nice.

[Post #3609] LGreen's amp is up and running. Looks good.

[Post #4371] Mark has shipped all the boards for the 2nd Group Buy.

[Post #4612-15] neychi posts pictures of his Krell style chassis.

[Post #4814] Mark G orders another 100 boards, for a third group buy of Krell KSA 50 clone PCBs.

[Post #4886] Mark and Lyndon have successfully operated a new Krell clone, not yet in a chassis, using Mark's boards.

[Post #4902] Luke finishes his clone and puts up some pics. Hopefully a chassis is in the works.

[Post #5260] Happy New Year!

[Post#6011] Bra, who started this whole thing (3/27/04), has finally built a Krell clone (3/18/06). Two years and 6000+ posts, go figure.

[Post#7180] and [Post#7186] Happy New Year!

[Post#7185] Once again, a discussion of fans and how to keep things quiet.
