The brass things i posted (P789) are not DIY, they're serial production heatsinks for 92s.
The bottom edge is flared to add some spring resistance that makes them clamp the little ones and not slide down slowly.
Making them like that is not all that easy, you'd have to machine a 2-piece mold to press the flare.
The easy way would be to fold a thin strip of brass/copper around the devices, then tighten it with a chica plastica

Thx a lot Jacco
I post this your pic again ( If I may)
Interesting too are the isolation of zistors legs ,
I didn't notice it the firts time a saw the pic.
Very nice and accurate work.

Leads have a considerable effect on the cooling factor of semis/resistors, from that on their operating temperature.
(for lesistols, the distance to the PCB is also vely impoltant, read a tech paper on lead length and mounting height from e.g. Vishay)
An amp case needs to be ventilated, the airflow within the case is not a stasis situation.
Most of the cooling will take place at the top of the Baldricks if the leads are insulated with teflon leggings, more uniform
Some day i'll get the matches back to Guernica

A propos sunido : My fate is that can't finish nothing
PS :
On the posted pics : are that simple wire you used to bind thetransistors together?

Manu,
my E-scargotier ist kaputt.
Sure me is in for the clickers, not nice to find another sucker and hit for the full 299 ?

Here is the tapping table that is good for New and Old World. I really hope you could read after compression. If you cannot, let me know and I will email it to you.

Yes, it will help metric challenged, but will be problem for color challenged. 😀
Beside that, metric people do not realize how fortunate they are and vice versa. Just to illustrate two of the same operations of adding two lengths and finding the middle point:
(7/16" + 8/64") : 2 =?
And same operation in metric:
(11mm + 3mm) :2 =
It is impossible to be metric challenged!
