Hey chchyong89,
Nice heatpipes. I don't have any experience with those. But, I have a question -- do you have them upside down in your pic? Don't they need to have the fins on top? I may be wrong here. But, I thought that there is a liquid inside the pipes which changes state and goes to a gas when it heats. The gas then moves up toward the fins and cools back into a liquid and falls back down toward the device and repeats the cycle. Isn't that how they are supposed to function? Or, am I incorrect here?
Thanks,
Steve

"Now we have just demonstrated the world's first electronic device in silicon systematically created on the scale of individual atoms," said Professor Michelle Simmons,

How about a atomic powered F5 for more gain, We could pipe the heat to neighbors.

Both I hope 😀
Blue dot supply caps may be either BC 22.000uf, 25V or Panasonic 10.000uf, 35V
Any opinions ?
Regarding 3-5watt resistors, any suggestions ?
Wirewound, film, carbon, or ?
Cviller boards? Go for the caddock MP 930's.😀 (Well not recommended in the power supply).
Didn't I post this a few weeks ago:
An externally hosted image should be here but it was not working when we last tested it.
I guess you dont like caddock
The curve shows induction ?
And the "better ones" are ?
Actually Im OK with wirewound "cement"
But they are inductive, which I understand is less good ?
Maybe MILLs are better ?
I found that I preferred the F5 with the caddocks -- the proviso is that they are heat sink mounted. i also liked the Ohmite TWW resistors. don't doubt NP on this one, value for money the Panasonics are just fine.
Bobo,
Is that from a toe kick heater? (under cabinet?) I've installed quite a few of those, and yes they are silent.

I got them from a flea market. I have been told they come from big computers.
I run them at half their rated voltage.

Tinitus, very good, but overkill. Solder is likely sufficient.
You click on the image, it gets larger... folks...
...but he is using a wire tie, like is done with heavy gauge AC wire on electric poles when tied to insulators (just a smaller scale).

On my Parallel caps I did it like this, because of the nice color contrast with the copper wire and brass bolts on caps, how ever doesn't always make good contact maybe didn't get all the enamel off the wire or not a good way ?.

Good 😀
Another thing
Looking at Panasonic supply caps I find that there are some nice ones with higher capacity and low ESR like say 20milli ohm
But some of them have much higher ESR, even in the same range and quality
Maybe they are designed for different application
I wonder if all builders are aware of that
I reckon the higher ESR could result in caps getting quite warm, or ?
😕
Ive used in parallel 11 Mallory 6400 uF 60 vot 45x80mm they not quite fitting for this circuit but they give a nice tone and detail etc to the amp in front of them i have 4 10.000 in serial with ov to earth on them. small caps I suspect have better ESR but using what i had still have 30 6400uF if any one what some ?
NOS. I cant even use them for door stoppers they just roll away.

bear, Ive just been looking at your site, and the way your power supply done on Symphony amp, its brilliant I'll get some copper I think,
you have to transformers in parallel ?
