Default I always use wooden small pieces, sometime thin MDF

This way i make the electrical isolation of the heat sink to the chassis or boards.
I do not like to complicate my life with insulators, screws, nuts and all those damn things.... and they are very bad to heat transference... i screw transistor mounted over aluminium heatsink, the transistor is checked if flat, because a lot are not, this way touch small part in heatsink, i check if heatsink is flat and i glued with epoxi directly in fiberglass or phenolic bord, and no difficult to remove if you need. I use alike everybody Silicone with dirty thermal compound and always a lot...must splash alike too much butter inside a bread... this way no air under the component.. air is not so good to heat transfer as metal contact... i sand, normally with the very thin sandpaper, here the number is 500 and done with watter to guarantee flat surface...have a metal block "guaranteed flatten", machinery made to be reference to me.

Sorry for the perfectionist, the one that try to make better than factories... and a lot of you do it better... this way i will ask you all permission to provocation.... to inflame you a little, to put some fire on this matter, to challenge someone.

Why?, if you spend so much time to make better or alike a factory... why not to buy?

Why?, doing the same appearance and quality assembling, why not to start produce it seriously?

Why? spend so much money to to something already done?


Why i answer this, because you boys, some young teenagers, and some new enginneers make better quality amplifiers than you find in brazilian shops (underdeveloped country i know), but here, theres a market to you.... why only be kidding when you can come here with 10K dollares and multiply it by 10000 in four years, our workman, unfortunattelly receive 80 dollares each month.... we have land, we like foreigners, sometimes we like you more than our own people, why to put in forum the picture, show to some friends, be proud and finish?

I do not want to tell you are crazy, but...... is not impossible that you can be.

Here, down in Brazil, our people sent money to foreign countries afraid of government sometimes stupid decisions, we need you!... lets go, move you ... and came hear to help you and help us.... sale this damn car and some other things and lets go to an adventure.
