Another Aleph ?? under construction..

blank527 · 4th December 2002, 03:26 PM

Well..

This is my current project..
I'm still choosing wich project.., an Aleph 5 or an stereo aleph 60.
Toroids are 625VA 2x25VAC..
Still got a little problem.., when switching on.., the toriods make a little hummm.., 5 seconds later it's gone.., then 5 seconds it reappears again.., anyone got a solution? I don't use inrusch limiters..(I know I should

), each channel is loaded with 130.000uF..

Thanks, Blank did you get all your parts at Radio Rotor in the Kinkerstraat

. This looks like a serious amp man, good job.

I think you can only post one image at a time. Not multiple ones.

Still the main question..
Wich amp.. aleph 5 (more bias?) or an aleph 60.
Someone who knows wich cures the hummmm?
I have in the mains (220V) 2 ferite cores for each transformer (like a pig nose

) to filter high-frequent..maybe that's the reason..
On the secondary I also have ferite cores but then only on the ground connection.. as seen on the inside picture.
Any help?
Thanks..
