huangyong 0 Report post Posted April 6, 2006 (edited) Hello friends, Since i joined this forum, i hooked up with this expensive hobby called DIY Head-Fi. Some of you might think that DIY is cheaper than Commercial products, true to certain extend, but when take the R&D cost into consideration, it might end up more expensive. I got myself a good job, and not much time left for this time consuming hobby, so thinking of letting go all these parts and components.

huangyong 0 Report post Posted April 17, 2006 hello, regarding MJ, it's almost done. except u need to solder in 2 3W 2.2k resistors (provided) in the powersupply board. I can help you to solder it if i'm free. you still need 3 tubes, 6922 or ecc88. and a high voltage transformer, 220V 6.3V (1.5A), and you will have the EARMAX Clone. for opamps, sorry manz.. i m not allowed to sell them here as warned by previous MOD, dunno the rules still valid not?? btw, my warning is 1 bar now.

I will bundled the whole package with 4 RCA jacks, one used alps pot, one EMI filter and one filtered power inlet. THE BOARD IS TESTED WORKING, SOUNDS GOOD. USING ALL TOP QUALITY COMPONENTS, DALE RESISTOR AND WIMA MKP10, RIFA .......... Share this post Link to post Share on other sites
