Here are my latest couple of builds:

Believe it or not I built these for my mother-in-law and she hasn't stopped listening for the past 2 days.

The cases were from the Italian company modushop.biz (HIFI2000). I provided the front panel cutouts/chamfer dimensions etc and they milled/machined them (for the preamp). I drilled the front panel for the amp. The rear panels I got from Front Panel Express.
Great service from both companies.

Others have asked about the switches -they were very expensive but I wanted a very professional finish:
I bought them from RS Components, but you may be able to get them cheaper elsewhere. The first part number shown below is RS Components part number.

The power (momentary) switch is an SAIA Burgess:
417-8618 Switch,pushbutton,momentary,IP67,TH9,black (SAIA-Burgess # 920000051)

The control switches are Schurter piezo switches:
456-1852 Switch,pushbutton,piezo,M16,aluminium,black (Schurter # 1241.2411.7)
 
It is this way to produce a picture for advertising purposes dear Epupa

The resistance is 0,47....the filter is not working as i do not use these filters...these boars are for my own personal use...family amplifiers having 1 meter audio cable only....filter is not active...parts are there to be filling component's holes only....and you know i use to do this way.

We had this same conversation in 2005....my memory is still very good.

To my builders, it is sugested, naturally, huge air core inductors,

The picture is for advertising only....alike a model only....do not work...you see, theres no audio entering and no supply

Ahahahaha!;)
