What should i do? Btw, the cmoy has no volume control and is at max volume (gain 6).. Using WIMA 1uf input caps.. Check the input to ground resistor OR replace the OPAMP and see....

Here's an old picture of my cmoy.  EDIT: For those who are now playing with point to point builds, I'm currently forced into building a simple dual regulated PSU for my final year project. Will share the layout and pics later. Remind me of my point-to-point LM3875 gainclone....now both units (as I have build 2 units) working at my friend's place and my friend's friend's place....

QUOTE(cba5566 @ May 21 2012, 09:00 AM) What i can say is building from "salvage". As i know musical fidelity x-10d don't use 7812 voltage regulator in the power supply section....but the internet x-10d schematic used it. Can someone confirm about this... It doesn't use for the amplification section BUT the filament section....

QUOTE(LittleGhost @ Sep 5 2012, 07:59 PM) Try to use a mix of both, like I usually do. Sometimes RS has parts E14 does not. Sometimes RS is cheaper, sometimes E14 is cheaper. E14 usually ask for order above RM150 for free shipping....BUT this month (September) they got free shipping for any amount of ONLINE order....

QUOTE(zy_xcup @ Sep 14 2012, 08:11 PM) anyone building NwAvGuy O2 amp? i was thinking of building one but omitting the battery and changing it to powered one.. is it a good idea? QUOTE(LittleGhost @ Sep 14 2012, 11:30 PM) why not? Though the addition of the battery circuit is very minimal in terms of cost. More likely insignificant. But one thing for sure,using battery sound better than using AC adapter only,due to the filtering circuit......

QUOTE(zy_xcup @ Sep 15 2012, 09:26 AM) but to change battery when its low is quite troublesome after a while.. but maybe i'm mistaken.. i've got the part list for the amp.. thinking of testing it first on breadboard.. i'm pretty much a beginner in this area.. That's why it got charging circuit for rechargeable battery

QUOTE(LittleGhost @ Oct 21 2012, 11:44 PM) Got the first half right  , not Noratel Toroid though. Too poor to afford one. My amp is meant for pre-amp/headphone use. Features: -folded cascode (yes fully discrete) -push pull darlington output stage (50mA) -Fully Class A Glad you're interested  It is designed for headphones. The PSU and the amp itself is designed from scratch. PSU is Linear Tech's high spec LT317 and LT337 (not to be confused with LM317/337).  Going to post more details after I'm done with the stress tests and benchmarks. Then where's your amp that drive speaker???

QUOTE(LittleGhost @ Oct 24 2012, 10:51 AM) Last time I jelly empire23 as well. He was one of the first amongst us old /audiophile/ diy kakis to own one. If you're gonna be doing stuffs like this, you'd have to invest in one set sooner or later. There's no way out of this  I'm saving money for an audio analyzer as well. Costs like at least 5k USD per unit.  Audio engineering sucks even more blood money than actual audiophilia. Audio Prism or Audio Precision???
