  1. Kerry, Just wanted to say that your software is awesome. Had been using the soft that was listed way back when the project first surfaced. It has some problems, yours is simply pure pleasure. Have it installed up in my T2 and just loving everything. Reckon the OLED display is real cool and Volume numbers are " purfect". You asked earlier about noise when using the 12v supply. Can't hear a single thing and the smoothness of this Att is Fantastic. Big thanks also to Kevin. I just taped off the 12v feeding the front end where it connects to the Board. Thanks again for all your efforts. Les P.S Just in case anyone wonders i'm using a Nano and the V1 board.
  2. Thanks Kerry, Noise was my concern to. So my back up plan was to install a small toroid transformer in the p/s and feed a separate 12v to the Att so as to keep it completely isolated from the Amp. Only time will tell, will keep you posted. Curious as to why the spec for the Filaments of the 6922 was specd at 1.4 a when total was about .7a. My ones are running at 7v which i dont like and i will have to add a resistor. With this winding loaded to 1.4a the voltage is correct.
  3. Well i finished my T2 build and it fired up first time and much to my delight with no smoke or flying parts. Have yet to put music thru but there appears to be no noise thru the amp with open inputs. With less than 100mv between + and - and 8v between outputs and ground i think i am a happy bunny. I am about to install V1 of Kevins Attenuator and was wondering about feeding this from a single 12v supply. I was considering taking the spare pin on the power sockets and picking up 12v from the power supply to feed the att. I will use the nano board to supply 5v and 3.3v. Is thisa good or bad idea?. Any other better suggestions.? Want to get this installed asap so i can listen to it. A long build but very satisfied.
  4. Did any one bother to check the 2sk246 fet before soldering it in?. If so how did you test it. By the way also any body thinking of these 2sa1486 which i think HKsouce sells then i think they are Fake breakdown at 400v, cant remember where i got mine from . Les
  5. Thanks, Still a bit hard to see exactly how much higher one is than the other. Any way i just soldered the octals hard down and the 9 pin with the pins just protruding thru the other side of the board. Les
  6. George, Yes you would be right. I see the original statement from Kevin was to put Octals down fully and then the 9 pin ones just barely thru the board, is that what you did. May just do that and if my sockets sit a bit to high then may disguise this with rings surrounding the base. As a matter of interest what was the height diff between sockets on yours Thanks Les
  7. Thanks guys, Kevin in my chassis i have to have the octals well down to threaded portion and the 9 pins bearly thru the board. George i think my pots will be fine after a remeasure. Re the cuttings from redrilling, as i have all my parts elevated i think i hopefully can keep everything clear. Did your octals have a bump half way down the pin?. Will take your suggestion and go hunting.
  8. Guys, I have completed my power supply and all went well. Now ready to assemble the Amp in the case. I have a dilemma, holes in the pcb for the octals are 1.9mm and my sockets have a bump on the pins which are 2.3mm. Can i drill out the holes or do i have to file this bump off What was the reasoning behind putting the pots on the backside ?. As i may have to change my pots to the other side due to miscalc when i made my case. My amp pcb is the original version from Kevin. All comments appreciated Thanks
  9. Thanks Kerry, All working well. Look forward to the planned upgrades. Les
  10. I assume i have everything connected properly as once it goes i can get the Volume numbers to increase from 0 to 127 and then back down. I see in the Adafruit example that they have a display init routine that does something like activate the charge pump . Any way dont worry about it, ill wait till you have it done the way you want, i am in no rush to display anything just yet. Just curious to try it out. Thanks Les P.S what was the card you were using, i have a Mega here which i am going to try
  11. Kerry, Still no luck, i am using a nano with Atmega328 and my display is a ssd1306. The new code would not compile on 1.6.7 ide like the last one did, so upgraded to latest. I still have to do the same to make it work. But now the V in volume flashes at a bout 1hz rate.
  12. I see, i have not gone with them anyway.
  13. Kerry, Have a look here. http://www.ebay.com/itm/316-Stainless-Steel-Lock-Washer-Medium-4-Qty-250-/200976064036?hash=item2ecb1b5e24 Les
  14. Thanks Kerry, Went with the nano so small enough to fit. Will try new code when posted and let you know. Now get back to enjoying that masterpiece of yours.
  15. Thanks Craig, Going with S/Steel #4-40 as you have. Les
