One, it's rude to bump a thread. Analogous to nagging.
Two, chances are that either no one has the schematic, or they don't want to share it.

Purer Thanks, do you have parts list too.

Hi Purer
Thanks for the schematic,
Do you have the parts list to go with the schematic?
some of the parts are burned black and I do not know the values of the resistors etc.
thanks

....and folks pay $2350 for this?

Mike, when I see your amps in shops worldwide, I'll accept your criticism of Krell's business model. Until then...

Many thanks for the schematics but what kind of file is this partslist? I could not open it with Winzip, Word, Excel....

rename it to "something.zip"

probably is downloaded to your pc without extension

 

[QSerraTico_Tico]

OK I am making progress. Got 5 files unzipped but how to open these extension BOT; OLN; DRI; TOP???????

 

[pinkmouse]

That's not what I have, they sound like gerber files.

Heres the one I downloaded, renamed correctly:

This is hard to believe... The input stage, the feedback loop and the bias sense are much the same as the older models. Not much change since the KSA-100 which may just attest to how good these older circuits really are. The only difference just amounts to paralled smallish semis. This could easily also be done with the KSA-50 and KSA-100 models. I wonder what sound differences would ensue??? Also what are the rail voltages in this amp...VH and VP? VH must come fomr a seperate supply.

There is no data on the drivers or the outputs on the spread sheet. The semi's would probably have to be well matched in this amp!!

Look at the schematic:a new way to adjust DC offset/feedback??????

 

[Mark A. Gulbrandsen]

Well... yes and no. It still controls the negative side of he doff. pair.... it just has a new take off point... probably to keep the parts count somewhat contanied. I do have to say that I am less than impressed overall. And I thought I'd be seeing some new outrageous design..... not so.

No other way, we have to clone this amp !!!
What value is bias?

 

[Mark A. Gulbrandsen]

Geez... If we keep this up pretty soon the powers that be that run this site will have to give in and make a page specifically for DIY Krell builders....
