The Pass Pub: The High-End Off Topic Thread

you know - when Spiritus Movens of most Insane thread in Papaland is disabled (back troubles again , but started limping , again ) .....

anyway - now I can say .... flesh is still weak , but spirit is moving

:rofl:

Perhaps you're suggesting, I heal myself with this?
Spirytus rektyfikowany ? Wikipedia, wolna encyklopedia
This was I use probably just magnetic head cleaning purpose...
Maybe you were sick?
The snow melted there?
We already have spring there now.
Poor Johan.
The snow makes no exception.
That's why I'm not going to ski.
Cold and slippery.
Rather, I'm sitting on top of a Papa-amplifier, and warming.
As long as I can pay the electricity bill.
 

Barcelona, got a Catalan family connection since +40 years.
Stopping by at Picasso museum for porn collection, really love that building since childhood. Marina for food, freak clubs around the ferry terminal to pass out. Hope me not forget food item shopping.

(mm, "ouch" doesn't quite cover it when you see finger bone sticking out, stupido me again)

Hm, I have an off topic question:
What could be the dye temperature of my FETs, in my four-channel F4 amplifier?
And how long lasting my semiconductors?
Some technical data:
The four channel amp draw 5A/230V, according to my Schuntermann.

At actual setting I measure ~0.6V at 0.47 ohm source resistors. So it is ~1.28A/device, at 30.5V source/drain voltage.
(I use two 1KVA toroid, which I gathered from my friend Sajti. They have 2x25V secondary voltages, among others.)

So they dissipate ~40W/device.
It is total 4x6x40 watt, it is 960W, it is might correlate to Schuntermann measure, see above.
The heatsink temperature ~70 C, at 20 C room temperature.
That's right, this yet my fakir fingers I do not tap it with pleasure.
What there may be the dye temperatures?
I use mica and goop, of course.
Till when may the FETs endure this?
Motto:?
The good sounding electrons are the hot electrons, it doesn`t matter, where are they came:
tube or semiconductor.
I apologise for my engrish as always, it`s came out straight my brain, without Google.

well - without going in too much of calculus in saturday evening , let's say that mosfet dyes are having at least 25C more than is wise to have .

why not using something as Papa's Koan Babysitter , or fan on each heatsink ?

Lazy Susan style :rofl: - 12V Noctua , as recently discovered by Dutchiewhale , are old and well known story .

regarding some Qs in previous post of you - snow is going down , my ill back are better and I'm also using Spiritus for usual Gusztav stuff (cleanin' da button ... and everything else )

your Engrish is much better without Google Drekloader
