It can't be that difficult to draw a schematic from the board you have. For that matter if you post hi-res pics of both sides of the boad many here will no doubt be pleased to draw a schematic.

Default BAD OUTPUT

Newark Electronic sales Dale, Vishays, However RCD resistors are as good if not better. http://www.rcd-comp.com/

Setting the bias could be trickey since there no room inside the amp. Also, you have you call Krell and ask them what the setting should be. I'd like to know that too.

My KMA250's has double sided PCB, that would be a neat trick to draw a schematic from that.

I don`t have the board - I just got pictures.
Here the backside of the board. This pictures are reduced in size otherwise they would be too big to post here - so the originals are much better in resolution.
To draw a complete schematic with values not only the transistor types are needed but also the values for the resistors and I fear that maybe this is asked too much from Alex - taken in account that he don`t know very much about electronics.

Hmm.... though not impossible to order, US is not only a little far away but also regarding Alex`s abilities in English maybe this is not the the best option.

Can`t somebody comment on those MPC`s resistors??
http://www.schuro.de/preisl-mpc71.htm
or here a description in English:
http://www.htr-india.com/products/cu...mic/br/new.htm

They are used in other high-end audio equipment as well
(refer to "Special technical features"):

or this kind (manganin) should be also suitable:

Hi ,
DON'T order from Newark. They will charge you with absurd high shipping & handling costs that will not show up on the website but are on the bill in the package.

Dales are available also from www.thl.audio.com in Taiwan.

The link doesn't work, neither does http://www.thl.audio.com.tw

www.diyparadiso.com in Antwerp Belgium has them and they speak german as well.

I believe you have to have $25 order, but the shipping is UPS or FEDEX.
I've never been charged a handling when buying from them.
