don't waste time thinking of them - all you need is on published PS schm
Single Cap under the temp switch is the normal 0.0033 line cap, the two black parts over the temp switch are no "caps" but 4A mini fuses...... :-)

Andreas,
how much did you pay for yours? Here in Finland they are asking 83 euros a piece & 30 euros handling fees - and a 4 pcs minimum. Gets quite expensive...

For the F6 I bought the KL-271 for 60,- Euro (both) of a friend of a German community

In February we bought some Seifert heatsinks (400 x 200 x 83 mm) for other projekts and wie payed 75,- Euro.
But we picked them up (it's an one hour trip) and the amound was 12 pieces.

Ok, just checking... I wrote Seifert and it so happens they have a distributer here in Finland, so they forwarded the email here. I had a suspicion about the price and it seems I was right. The price is more than double here..(!)

I quess I'll be making more inquieries else where...

Thanks!

Default R13 and R14 Power Dissipation

Can someone tell me the wattage value of R13 and 14? I searched and tried to calculate it, but the Ohm's calculations don't make sense.

Ohm's Law Wheel

If I use this Ohm's law wheel, it's R * I^2=.24w, is this correct? Doesn't sound like it is. What about the voltage?

23v^2 / R{.1} = 5290w? No way.

23 x 1.55 = 35.65w? No...

I thought Ohm's law was suppose to be easy?
What's missing? What's the relationship here?
Does something else need to be figured out before putting in the values into Ohm's law?

Looking at the F5 sense resistors, I see a 3w resistor.
Is 3-5w resistor close enough?

Hope this gives you good insight into the confused mind.
