digi01 0 Report post Posted November 22, 2004 (edited) Hi all,I am come back from vacation here is my BB amp diy experience,im glad to sharing this. pic1,one channel boards(4+4 pairs quality transistors as output) Edited November 22, 2004 by digi01 Share this post Link to post Share on other sites

digi01 0 Report post Posted November 22, 2004 wonder where is all those JFETs?? and opamp (DC servo)? its still in progress very hard time to those P2P wiring. Share this post Link to post Share on other sites

huangyong 0 Report post Posted December 5, 2004 really looks good. do you match all the transistors? Share this post Link to post Share on other sites
Q00 0 Report post Posted December 5, 2004 reminds me of mr gilmore's latest solid state amp in the diy forums but that is a whole other beast....... digi01, im just wondering on the anticipated heat output? Share this post Link to post Share on other sites
digi01 0 Report post Posted December 6, 2004 to huangyong, yes,all the transistors is matched. to QOO, I think the amp can output at least 2x1W.the transistor that I used is 120V1A0.9W pairs B647/D667. digi Share this post Link to post Share on other sites
huangyong 0 Report post Posted December 6, 2004 (edited) 1W output per channel only? can it drive AKG K1000? what is the difference if compare to the original 1815/1015 transistors. price. seems like the price of the transistor is not cheap.

digi01 0 Report post Posted December 6, 2004 1W per channel.surely it can drive K1000.i'll set up a 4pins socket for to feed K1000. yes,the parts of the amp is costly Share this post Link to post Share on other sites
Mackie 0 Report post Posted December 6, 2004 (edited) Don't wanna be a damper but I've tried K1000 driven by Audiovalve RKVII via headphone and speakers output (3W/channel) but utterly not impressed. Of course, the power is sufficient to drive the cans but I suspect more headroom is required to push this cans near their full potential. Later research revealed K1000 may only sound optimal with a healthy feed of 7W and above. YMMV. Edited December 6, 2004 by Mackie Share this post Link to post Share on other sites

huangyong 0 Report post Posted February 3, 2005 WOW.. the board looks cool... where you got it? and one more suggestion is use turn pin for those transistor holes, easier for troubleshooting later (matching problem). Share this post Link to post Share on other sites
