hacknet 0 Report post Posted April 3, 2004 i`ve just finished building my gainclones. have a read and see if these could be effectively used as a headamp... i think it can be done with the help of 2 dropping resistors.. am i right Gainclone-Z Share this post Link to post Share on other sites
jtfoo 0 Report post Posted April 4, 2004 56W chip amp to drive a headphone, that's almost inifinite headroom... Power man.. Share this post Link to post Share on other sites
hacknet 0 Report post Posted April 4, 2004 yup, on top of that, the chip sounds really clean. kick bass plus detail to the max... i wonder how my present pair would sound like.... Share this post Link to post Share on other sites
jtfoo 0 Report post Posted April 4, 2004 Let us know when you managed to convert your gain clone to a head amp. Should be interesting.. BTW, nice PCB work.. Share this post Link to post Share on other sites
hacknet 0 Report post Posted April 4, 2004 i probably can make a few for you people for an extremely small fee... i`ll look for the right combination and i`ll come back to you all... Share this post Link to post Share on other sites
jtfoo 0 Report post Posted April 5, 2004 (edited) Cool, but I'm more interested in your Zen V4 PCB.. don't mind paying you a small fee for it. If you could also do one of those Pass's zener diode regulated power supply, that would be even better. Edited April 5, 2004 by jtfoo Share this post Link to post Share on other sites
hacknet 0 Report post Posted April 5, 2004 wow... you are fast... i have already designed the ZenV4 pcb. i am intending to etch this friday. full SMT components. i don`t mind selling a fully populated board. call me at 91084462. we certainly can work something out...

jtfoo 0 Report post Posted April 5, 2004 Why SMT?? Very difficult to change if canot work or need some tweaking... Share this post Link to post Share on other sites
hacknet 0 Report post Posted April 5, 2004 not true... its space saving. especially good when the photo board isn`t particularly cheap. its also alot easier to design for as it takes up lesser space. Share this post Link to post Share on other sites

jtfoo 0 Report post Posted April 6, 2004 The number of components seems to be too little even if you take away the regulated PSU away. Is it just a single gain stage without the active current source? Share this post Link to post Share on other sites
hacknet 0 Report post Posted April 7, 2004 active current source, and a buffer stage. no regulation. the board is only missing 4 1.5k resistors and the 2 mosfets. Share this post Link to post Share on other sites
jtfoo 0 Report post Posted April 8, 2004 Your pic only show one IC which I assume is the mosfet for the gain stage. Where're the others IC? Should have one more mosfet and a BJT. Share this post Link to post Share on other sites
hacknet 0 Report post Posted April 8, 2004 nope, i`m missing the 2 main mosfets. the BJT is mounted behind one of the caps. you can barely see it. Share this post Link to post Share on other sites
jtfoo 0 Report post Posted April 8, 2004 I hope you don't mind showing how the two mosfets are mounted. By knowing the orientation of the mosfets, it's easier to plan on the method of mounting huge heatsink. Share this post Link to post Share on other sites
