Since we can add or change what we want, we surely can change the fan ?!

But I will use 2pcs for my stereo amp, 1 heatsink for each channel.
8x T0-3's per channel.


Also I can order the heatsink in rawprofile 1 meter for those who want to make their own heattunnel.

I'll make one more try with toroid.com.

I reduced specs to bare minimum:
Primaries:
dual 120V

Secondaries (total 5 windings)
bifilar 2x 38V RMS at 12A RMS (39.5V 0a)
bifilar 2x 60v RMS at 0.8a
single 18v x 0.8a

STATIC SHIELD between primaries and secondaries.
MAGNETIC SHIELD = 70mm

KSA100.2 versus 150

Gentlemen

Some time back I made a posting re the sonic attributes about a Krell 150. My initial impression was the KSA100.2 was better.

We had some thunder and rainstorms in Cape Town and somehow it must have triggered the amp to switch on whilst I was at work. Needless to say I came home and the amp was cooking hot.

I started listening and I was extremely impressed. I have not heard a amp sound so good in a long time. I have to withdraw my previous comments. This amp is stunningly good.

Now I am just wondering what will happen if I leave the KSA100.2 on for a day....

On a more serious note- does anybody have an explanation how this process works ?

Regards to all

Jozua

The last goldplated MK-G KSA100 boards have found a home, the very posh KSA builders club now includes a Bulgarian member.

Just a reminder :
anyone with a desire to build the KSA100-MKII is welcome to contact me for 1N5309 CRD's, still plenty left for a number of stereo sets.
(i sell fish too, though the mackerel is a bit off lately)
