aaa 0 Report post Posted March 23, 2005 Creative selling 1212M for $369. Cybermind in SLS list it for $359. So I went down to Cybermind today. While I was about to make payment, I ask the sales can lower the price a bit? To my surprise, he give me $355, don't know such major shop also can bargain one. If anyone is going to buy another 1212M, maybe can try $350. Still evaluating the PCB to find out what all the caps are for, will post more details later.

huangyong 0 Report post Posted March 24, 2005 did i see opamp? 4058 possible to desolder? Share this post Link to post Share on other sites
aaa 0 Report post Posted March 24, 2005 Yes the squarish JRC 2068 is the dual opamp. Two are used for DAC and 5 are used for ADC. Each chip serves one channel, one opamp each for the +ve and -ve signal (0202 has balanced output) all technical discussions that has nothing to do with the local context (like where to get modding parts here) pls post at http://www4.head-fi.org/forums/showthread....86&page=1&pp=20 Share this post Link to post Share on other sites

av98m 0 Report post Posted March 30, 2005 Nice!. The Oscons must have accounted for most of the parts cost. Share this post Link to post Share on other sites
aaa 0 Report post Posted March 30, 2005 huangyong, I'll show it when I take my card out for phase 2 mod, which may take a while. The pad surrounding each TTH hole is very small, and the surrounding plastic melt to form a sticky layer that stay sticky even after cooling down. So it's not really modding friendly. av98m, you are right, the F size (D=10mm H=11.5mm) OS-CON cost $2.50 each. And the killing part is that the stock is extremly in complete, I have been force to use 680uF for places that I'm looking for 100uF. Share this post Link to post Share on other sites
