Kippei 0 Report post Posted January 12, 2006 I was wondering whether i should use a JJ or a mullard... I still have yet to tested a millet..... to figure out the differences Share this post Link to post Share on other sites
Kippei 0 Report post Posted January 12, 2006 Darn... I think building a millet in the future is deem impossible... Hard to get the tubes in term of economics. Share this post Link to post Share on other sites
squalle 0 Report post Posted January 12, 2006 (edited) read in the headwize thread. errm see if the output oscillates erm imbalance? I think even alps blue would have that at near minimum. hmm right now two PCBs? hmm those folks at headwize planning to split signal part and PSU part. I dont think it should be a problem. can you chk if the ground output of ur LM317 is really 0 volt? chk the voltage agains earth may I know what source are you connecting it to? ADD: I saw this in head-fi, quoted from morsel: "Input ground, case, and pot shaft/housing should be tied together" I almost forgot abt that fact. so yea, try it. It solved my problem for my 1st amp I built Edited January 13, 2006 by squalle Share this post Link to post Share on other sites

I still have yet to tested a millet..... to figure out the differences errr why not each of us buy different ones and then we loan to each other to swap around? at least now there are 3 SOHAs, with all spotting SAME tubes! haha koba must be very happy Share this post Link to post Share on other sites

squalle 0 Report post Posted January 13, 2006 hmm maybe you just dont like tube sound? Share this post Link to post Share on other sites
huangyong 0 Report post Posted January 13, 2006 hey... dun be disapointed la.. i dun like tube sound also.. stick to solid state la, try discrete design!! Share this post Link to post Share on other sites
squalle 0 Report post Posted January 13, 2006 yup agree with that sound is just like food. you and me would prefer different kinda food Share this post Link to post Share on other sites
kross 0 Report post Posted January 13, 2006 well, i am using a cd6000 for this mhha amp and since the gain of the mhha amp is quite big, it really sounds loud so i have to turn the vol pot to really very soft volume. well, right now all my signals part are on 1 pcb with its own ground and this ground is connected to the main filter cap ground by a wire. the input ground, output ground vol pot ground and shaft are all tied together before going through this wire to the main filter cap ground. when i have time i'll check whether the lm317 is 0V against real earth. well, i must say for $20++, the mhha amp is really good for performance. well, i have not heard those higher end amps, even the ppa. but for $20++ (not including the sweat and frustration) it is really a good amp. the vocals are better presented. and also in the process i get to learn quite a lot of things, which are interesting.. so squalle which 'food' u like? tubes..??

squalle 0 Report post Posted January 13, 2006 haha pay me, I build SOHA for ur roomie SOHA supposedly to sound better than MHHA (no output cap and tube's running at a higher voltage) oh btw kross, I prefer tubes to ss Share this post Link to post Share on other sites
