The diary of a C(l)onehead.
2004-01-28 today I finally decided to order the PCB. It was ordered from P-A Sjöström.
2004-01-30 That was fast! today the PCB arrived VERY nice card indeed.. Unfurtunally no time to start up my Weller.
2004-02-09 Transformer arrived
2004-02-09 Chip arrived (thnx to Fisksmisk Ola at Hififorum.nu (what a nick:)))
2004-03-06 A little boxbuilding and soldering.
2004-03-07 Soldering the last parts and of course there was some parts missing (2blooody FKPs)
2004-03-08 Boxes as good as done. only minor things left like feets and LED and another mains switch, maybe even some text engraving . The boxes look quite good for a 0$ budget, box parts and heatsink are salvaged part.
2004-03-13 Changed the main switch and did some engraving I took the liberty of renaming it from "QRP-01" to "QRP-01.k" the "k" is to mark that it was build by me, Keld. I hope that Mr Sjöström doesn't object :).
2004-03-22 Now I have been listening to this gem for more than a week, and it have added a new dimension to the sound so I think I will have to keep it hooked up and I think that the WAF is good enough. SWMBO actually came home in the middle of one of my listening sessions and said " it sound so clear even though you are playing that loud" that took me over a week to reach the same conclusion she just walks in and and heard it for a second..
Now that you have come this far you can just as well have a look at some tests I have done : click here
