Ok, some test-porn.


Just made it to see if it works, to not waste my PTFE board, and test how the compensation worked.

The real thing is soon to come.

thicker ......... but not too thick .....

dumb ........ but I'm always dumber ........

:rofl:

good ole L profile , also known as Winkel 😉 ,

40x40x4 mm always seems good enough

just look on pics of Papa's old Alephs , and some other hot amps ;

what you wanna see as "enough meat" , is certainly good for your amp too .

I was thinking for a 6" high heat sink, 4"x4"x0.5" .. too thick? 🙂 combination heat spreader and L bracket.

I've never seen copper L profile either my Danske friend... I'm not sure if one can stick copper plate in a sheetmetal brake either...
 
when it comes to doing new and strange things to metal, you can bet Magura has done it

As always, thicker is better for heat through metal. Surface area rules for metal to air transfer -- but if your fins are too long and the ends are cold, that surface area isn't helping you any.

if I can cover the entire heat sink, that's good too

Are you sure ?

Suppose you go one step further and wrap the bracket around the entire heatsink surface, what happens to the heatsink's Rth ?

A bracket requires a reasonable flange thickness to prevent it from warping.
It's the cross-sectional area at the 90 degree angle crossing between both flanges that is of importance.
The prettier bracket will look like this =>

whazzat ?

I'm back in time , on top of my back problems ?

I think that I saw two LL's posts - one worshiping MGs and "soon to be here " Tannoys ..... and another one with pic of usual DC blocking gadget .....

Steen - I also adore MGs ...... but I have opportunity to live only with pair of SMG's for a while , driving them with skunky EL84 SE amp 😉

hehe ...... besides some other ...... multi-hundred watt ones 😉

believe it or not , Apogee Minors were pretty same in character .... you can sleep with them singing .....

regarding Tannoys ....... you can't beat olde horn coffins ......

😉

Tannoy 15 inch 385/HPD's are one of our primary in-house
references. We have three pair using Joe Sammut's extra-
special crossover in Jensen Imperial and Ultraflex enclosures.

😎


:bawling:

I have just these ones - Poor Serbian Man Tannoys .......

:rofl:

edit:

seems that Steen deleted these two posts ..... but dunno why .... 😱
