selling above discrete buffer for direct replacement of HA3-5002 or OPA633. if you happen to own a PPA v1 or V1.1, this is a good upgrade for you. i gave up my PPA project, these buffers are doing nothing for the past 13 months. you can get discrete buffer for more than S$100 out there, but i am selling $30 to benefit local PPA owner. PM me if u need, sell as a set of 3. cheers.

hey uncle heady. wan to build tube?? came across this in taiwan webiste.. the kit include eveyrthing.. for about $176

seems like Fubar is better overall for its spec and size.

new one is S$550 @ Stereo Electronics.. just FYI

Omega 2 Should go with Blue Hawaii

nice vocal... try a song from baidu.. hehe.. indeed very nice.. will buy the cd

okok..PM u la..

how much it will cost roughly?? can try out yours first??

I would love to, if you allow me to mod yours..

I thought it was God... since when demote to King???

are you selling that?? can try out ??

ooh.. paiseh.. just saw the opamp..a bit difficult to make the opamp replacement la.. haha. discrete someore.. may be we make tube one alright?? hehe..

wow.... 40% prefer it to be below 100. come on.. more feedback pls.. if the response is good.. hehe....

hey fren, those are not opamp la.. just a low power discrete regulator. you wan to try?? may be we can try using chip LM317 then REF02 + an opamp, or TL431 + transistor.

Nowadays Commercial DIY is very common. Even I think Headamp and RS is considered in the same category, just that they are high end. i think this is entrepreneurship.. more and more hobbyists start to sell their own amps.

expensive!! shall we DIY too?? hehe..

ok thanks ahdui!!

does anyone have it? may be i just borrow first. and that Ubi Tech Park sounds very ulu. dun think will go there just for a reamer.

dont forget AD1000 too.,..

Ubi?? where is that??

small and nice.. will need this for my computer...too bad the opamp also SMD. how nice if it is a DIP type.. swappable.

yeah...the God of EAR

just called uncle wilson, he said he is going to set up in the next few hours time.

this is an interesting idea. and not that no one done that before, just that it is the big brudder's game. For example, carrefour has big sales volume for a product, so they can use this sales volume to negotiate with the product producer to lower the buying price to maximize the return. Well, if the producer refuse, the they will lokk for another producer. it's the current trend now, that's why ppl start to do MO. MO gives mass purchasing power , and that will give you very good bargaining chip.

where can i try it??
