Thank you twitchie! (My first fugly, woohoo!)
Yes it’s a mini dissipante 3U 300 deep. (Given the easy temperature, I‘d dare to even go 2U on this, except for the missing space—nema problema with an external psu of course)

How much can these bastards be pushed wrt dissipation per device, of course given chewing gum or the likes as thermal conductor?
getting more and more interested…

I gave you my recipe
not that is best one or only one
though, I'm already notorious - regularly forgetting to turn fan On on my T-Beds, so everything ending redchillihot, for who knows how long
that happened to my Old Soul too .... and I was relieved that 2N1099 survived , no gurgle
though, of lately, I'm avoiding to turn fan(s) Off
Butbutbut, if mine barely get warmer than 40-something °C while running at 85mV, and went up to abovish 50°C at 110mV, how hard are you running them then?
25V rails, 1A Iq
they were X*?@! ....... and survived
though - I'm saying - they survived, but I'm not saying that I would dare to use them that way in prolonged time

no
they're helluva with fan
tall sinks are not that efficient as they are if you cut them in half and put same heat in them
besides, it was convenient (first page pics) to mount my GE Biguns on very top end of htsnk..... not happiest place, when fanless

Ok, but I wrote physics (not -ist)

(I‘ll stop cluttering your thread here, ok? ZM, it was a greag adventurous journey, many many thanks for this and the old soul! <- serious)

the best plumbers around!!Papa is Physicist
Edit: never was good with quotes, and once I learned it, forum was upgraded. Looks OK now
An absolute must for physics guys that hang around a cyclotron - find and fix water leaks
A quick update: Over the weekend I replaced the 2n1099 in the broken channel as well as the mosfets to avoid any potential issues. Bias was uneventful.
I left it playing on test speakers for about 15 hours with rail fuses. After that, I removed the temp wiring with the fuses and ran for a few more hours.
I noticed that with the lid on and running for a while, the quiescent current drifted down a bit; I'll probably leave it as is.
Cheers,
Dennis
