Guys, if u dont mind me interrupting.
How do u cut a say 3 inch hole? I use to DIY myself but the outcome aint always nice. I'm thinking of DIYing a SOHA II but I'm having difficulties drilling 2 holes on the top of the casing for the tubes.

can always "pinjam" some one's milling machine..

anyway there is this special adapter to fit to a drillbit..can cut fairly large (inches) circles on metal plates with a electric drill

Steel is a little bit harder though... easier on aluminium..
As per LG's process but I'd drill a series of small holes.. about 1/8" max., very close together. Once completed, 'punch' out the inner metal and use 1/2 round or rat tail file to smoothen the hole and adjust dimensions to suit the object going through the aperture wink.gif

wei then it'll look very kraftangan effect.. tongue.gif

That's what I've been doing but the hole aint always beautiful. Since the 2 holes for SOHA II is not hidden, i want it to be as smooth as possible. Any companies in Msia that does this sort of cutting? =)

plenty..but need to pay or maybe they won't want to do one off basic jobs..

Probably it is because no one is interested in it?

'better' is subjective. It is all a matter of preferences, one man's meat is another man's poison. tongue.gif
Between STKs, GCs and T-Amps each have their own strentghs and weaknesses and NOT really the same platform to be compared with.. just a different means of amplification. At the end of the day, let your ears decide! biggrin.gif

what does your ears say?
