  1. Hmm.. how would the R2 value staying at 100k affect the overall circuit? Thanks in advance for the forthcoming enlightenment. Read the META42 article on the signal cap value and u'd know why.. I'm not about to spoonfeed ya. It's in the original META webby I suppose? It's late.. i'll search tmr. Thanks.. seems like there's still hope..
  2. Completed my CMOY. It sounds like a MALFUNCTIONING RADIO WITH EXTREMELY BAD RECEPTION!!! Lots of static like sound... Tried it on a headphone for a few seconds but my ears begged for mercy so i used it as a preamp and I could hear it more clearly on the speakers alot of static like noise. Could it be because of the PIO? Old caps sound like old radio... My previous CMOYs without any caps didnt sound this bad!! I'm gonna scrap the PIO... gonna save me alot of board space. Are the Evox Rifa caps any good? AHHH... MY WEEKENDS WASTED!!
  3. Guess I was too carried away to forget to read the datasheet.. my apologies... Hmm... then I suppose I can use the TLE2426 to power a pair of opamps after all. Thanks for your enlightenment.
  4. Thanks for your input. Any idea how much it draws for the worse condition? Thanks. I guess i will settle with a simple voltage divider as per Cmoy schematic. The PIO caps are taking up almost half of an Altoids tin can. Oh yea, I got an Altoids tin can, found it somewhere in the house.
  5. Hmm.. after looking at it carefully seems like it wont work... Any idea how much current these opamps draw? TIA.
  6. Did up something... http://www.villagephotos.com/image.asp?id_...256&sessionkey= Compared with the PPA supply, this has shared ground (not sure if PPA is sharing ground) and lacks a few transistors to attenuate the noise (right?). Would this work? Thanks. (never used villagephotos b4. if pic doesnt show, try: http://www.villagephotos.com/browse.asp?selected=820071 )
  7. Hmm... have some questions regarding the TLE2426. I'm afraid it can't supply enough current to the opamp. (most probably OPA627, 637 or AD8610) Are there any solutions to it? Tangent audio mentioned BUF634, but that's gonna eat into precious real estate. The PIO caps have already claimed owner on a large plot on land...
  8. Hmm.. how would the R2 value staying at 100k affect the overall circuit? Thanks in advance for the forthcoming enlightenment. R5 is optional, but is it good to have one? Thanks once again. Got that socket from Koba. It is inside the bag of normal sockets... just gotta look hard enough.
  9. I think so too. Anyone got surplus of that Pengiun mint?
  10. Hi everyone. I would like to view the schematics of some CMOY amp variations, could some kind soul put it here? THank you! I have acquired the following components for the project. 2* Matsush*ta (Panasonic) LXF series 680uF 16V capacitor. 4* 0.068uF Nichicon 'Paper-in-oil' (PIO) capacitor. 8* 1% metal film resistors. 1* 5% carbon resistor. 2* 3.5mm socket. 2* 4-pin DIP IC socket (Made by Texas Instruments... patented. ) Anything I left out? I plan to parallel 2 of the PIO caps to get closer to the 0.1uF. Takes up alot of real estate, but it is PIO. Planning to use the TLE2426 virtual ground driver to obtain ground reference, instead of using a voltage divider ala CMOY style. Please advise. Thanks a million!
  11. I want the Sponge Bob one. Can someone help me buy? I don't have a CC to qualify for a eBay account. Thanks. I probably only need 2 of the 6, but will take all if there are no other takers. Thanks in advance.
  12. Thanks. Seems like only the Hudson and that chinese sweet is available in Singapore. You got any of them up for sale/giveaway?
  13. Everything comes in non-recycleable (a.k.a. use-and-dispose) package nowadays. Just saw the Hudson at 7-11 for $3.08. Seems a bit 'long', which makes it look kinda improportional. Any comments on this tin can?
  14. Thanks for all your inputs. Guess it isnt easy to get tin cans in Singapore.
  15. Just saw the Dilbert tins... Any place I can get the tins locally? Thanks.
  16. Have scoured through the last 4 page but found nothing related to it, only a comment by Firefox stating 7-11 and Guardian retailing Altoids, but it is followed by a comment which says the Altoids cant be found at 7-11. As so, I would really appreciate it if someone would tell me where to get it. Thanks in advance. I don't really like the Hudsons. Prefer the Altoids and the Penguin with the striking background. Thanks once again!
  17. I'm a happy user of the megaworks, no blown subs... Francis' Megaworks blew after a few days of blasting.
  18. There's only a single version of the 627, sad to say.
  19. I supposed the tubes work as a buffer?
  20. no OPA627s but i still prefer the AD8610s... btw Ruach, i'm w00t from echoloft.
  21. the chip that addresses the PCI bus (Envy24) is the same. but the DAC and stuff may not be.
  22. oo.. so only have to replace 3... thanks.
  23. wah.. this kinda desodler method ah... i rather use hot air gun.. but afraid the other smt stuff ard the opamp falls off leh.. btw, i read finish whole thread still no idea which are the opamps to change..... or shld i change all thx again. may replace all the output caps with blackgates when i have the moola
