I'm hoping you guys haven't had the thought "Damn, I'm wondering what the Nomnomnom guy messed up tonight" lol especially after my last post last night.
- Just to ease the least of your thoughts I had no visions of crazy little exposed wires laying around ready to ground themselves out to anything, the only thing that spawned my post last night was a little thing that could tide me over until what I hope is to be my last order from Digikey or Mouser (but they killed me on shipping last time lol). I'll spend tomorrow after work figuring out exactly what I need to complete this project so I can place one final order (to include whatever I may need for the grubDAC).
- I haven't posted anything tonight because.... well.... I've been listening to some amazing things out of my headphones (T50RPs and 225Is) for the past couple hours. Is there nothing this amp can't do? The dynamics are absolutely insane, I pushed my poor drivers and my ears to the MAX (
) and neither failed (I only pushed my ears so far). I've never heard such authority from either of
my headphones.
Guys, I'll say it again and again if need be. You've helped me through this when I had no clue and I appreciate the hell out of it..... Thank you a million times over....
Voltage is reading a very steady 27V
Tube bias is right around 13.5V but it's a little jumpy (settling nicely though)
MOSFETS are at an awesomely steady 260mV (I'm keeping a close eye on them, the tubes and the voltage)
Nothing is "CRAZY HOT", offensive to my olfactory senses or sending fireworks into my vision.
I plan on compiling all of my experiences together to write a fairly explanatory new thread at some point and time over this coming weekend. I plan on aiming it at noobs like myself that may have a few questions, maybe some of the basics that they (like myself) overlooked. I have also started some plans on casing this beast up but I really want to make something special so it may take a bit.... Oh yeah, I definitely have to assemble my grubDAC and see how that sounds too. For some reason I don't foresee disappointment in my future lol. My shipment from all-spec with some SMD tools (tweezers and .80MM chisel tip) should be in tomorrow so.... Some more fun tomorrow night....
Everyone in this thread that has helped me through this is FREAKING AWESOME. You are experts in your field (hobby?) and are to be commended. I thank you a million times over BUT... I do have one thing to say to all of you.... None of you has welcomed me to Head-Fi with the obligatory "sorry for your wallet"...
Not worried FYI, I've already apologized to the poor old leather guy a million times over hehehehehe....

Oh crap and a pic explaining the non-conductive temporary solution to my biasing needs and I have to say. The probes fit perfectly into these "12 position - Female - Interlocking Connector" (#2740242) from Radio Shack and I labeled the inserts with permanent marker covered by clear tape. Frees the hands up and clears the test areas to turn the trimpots to your hearts' desire!
Yes, that's electrical tape around the power socket (I try to learn from my electrical mistakes lol). The T50RPs sound absolutely awesome and my SR225Is have never sounded so.... Grrrrrrrr a word considered to be a swear would be perfect here but "engaging (?) will have to suffice.
From what I hear I really can't wait to assemble my grubDAC kit. If it's better than the uDac2 then hmmmmmmm, maybe that case work will have to wait a little longer lol......
