PCB Layout for Hiraga Le Classe A?

ralf · 21st April 2003, 02:17 PM

Hi,
has anyone a layout for it?
Which transistors are suitable?
has anyone compared le classe a with le monstre or JLH Design?

thanks,
Ralf

Actually, I found this link some time ago, and the Hiraga Classé is a known construction for quite some time now...

A few months ago I promised a friend of mine to help him with a Class A project, -- some 10-20Watts, and this is one of the possible solutions ( along with JLH ),. However, some of the transistors here are obsolete, and hard to find...
Has anyone seen a replacement list...??

...no. i searched substitutes, found something (i forgot), and failed in bulding it.

Try JLH it`s wonderful and well supported...

regards,
Ralf

Hi AuroaB,

the link I posted had a URL to a source of the transistors in the schematic.

Hi Ralph,

due to some rest from work I had time to read more posts in this forum.
In the past I have build JLH from Fig. 2 of Geoff's webpage, as well as Hiraga Le Monstre and 20/30W. All three designs sounds very musically. In my systems I can not define any significant differences in sound reproduction, thus I'm very happy with such designs.
Regarding Hiraga PCB layout and Transistors you can address you at "La Maison de L'Audiophile" a Paris,
Phone: +33 1 40331133, they have all transistors (matched pairs) on stock to acceptable costs.

Can you please tell me what kind of PSU did you use for Le Monstre?

Thanks

Do you know if the shop is still in the "Rue de Belfort" in Paris ?
