wanted :100W Aleph X (kari's board) bom/parts list

[dhole]

Hi there

I would be interested in a parts list or bom for a 100w aleph X . I have a set of Kari's boards (excellent boards I must add) . I just thought someone might have done some of the hard work already, then I can spend more time making a chassis Thanks in advance....

G'day

Component values are printed on the boards, however I have this using RS components.

Also this guy, made a BOM for a 100 watt's. Monoblocks, right?
Lots of usefull info on Thomas Chaos page.

BTW. 100 watt's A-X's spells serious heatsinking!

Assears, I thought the parts on the board are for Greys original Aleph X which is 45w or somthing close , not 100W...?

If you have Kari's boards, I think they are meant for something like 70 watt's. Grey's original used 4 fet's per channel. Kari's (KK's) uses 8. I think to get 100 watt's you are looking at 12 fet's per channel! You need the outputboards of Kari's or to hardwire them, as I did.

BTW. these four heatsinks is for one channel

Assesears , is your parts list for 100WPC ?

Cheers Steenoe

I have six of these heatsinks....

[Assesears]

No Kari boards about 100W, 5 to 6A bias I think.
Yes massive heatsinks needed again have to save up some money.

the sinks measure 65cm x 12.5 x 8.5 . that would be 3 sinks per monoblock. Any comments ?...

Go figure! I think the source resistor value on KK's and Karis boards is a bit on the low side! I wouldnt be confident running that amount of Amperes through only 4x2 FET's. I prefer 4x3 FET's. But this is just a gut feeling

Assesears, have you built yours yet ?
