Pumpkin preamp - ordered by Steen , official making thread

Nothing broken today...
Hehe.

But you sowed doubt in my mind about the method used to thermal coupling the Zistors.

Would Schrumpfschlauch/Heat-shrink tubing/Krimpkous (thats for frère Jacques) instead of tie-Wrap be a better solution?

No, it would not offer any tension once just around 45C, cause it turns soft at that temperature.

Zip ties or metal is the way to go.

lookie lookie

they make weaker drills lately ....... in Ostrich ..........

:devilr:

I have tried on many occasions to tap sinks and always ended up drilling right thru cos I screwed up(no pun) and using a nut and bolt.

Is there a dark held mason's secret to this..If so could some kind soul please explain the tricks. I have a pillar drill and a set of metric taps(only one for each size tap).

what's point ?
in through hole you make or in bigger dia hole ,than you need ?

through hole is a must - in 90% of situations , and exact dia for tap is easy to find ;

trick is in steady , slow drilling , lubricating is a must ( WD40 is handy , even if I use some more esoteric stuff - and you don't wanna know that's in fact nothing else than goat fat).

tapping - again lubricating is must ;
half turn right , then half turn back ........
coffee is obligatory , too .......
and no hurry

sounds easy ?

For tapping in soft material like Al, I now prefer to use Hand tapping tool as I ended having must less broken tap than with drilling machines. I found that, this way, it is so much easier to control.
Lubrification with common lamp-oil (cheap) but I am not a profi.

For drilling, the opposite. I prefer pillar drill (broken drill on ZenMods pic is the result of free hand drilling on kitchen table, smoking and drinking a beer at the same time)
