Thanks all, i will check my mosfet connections. hopefully its a simple mixup of pin 1 and 2. I am hoping that is the case.   If not...ill go back to the drawing board lol. I instantly regretted twisting things together because if i made a mistake its basically impossible to get apart.

Ok,   Here are some more pics of my build, As I said earlier the green and white wires are 99 percent connections and the blue and orange wires are ground wires.   I have many problems and I am open to all suggestions at this point. my first problem is how to stabilize my connections. I...

update to my build, I have decided that I need to start from scratch for my build, so i will be ordering new caps and resistors.   I was able to get faint noise from both channels, but only if i pushed around some of my wires. It seems that I have hooked everything together correctly...

can anyone explain to me which side of the potentiometer the ground wires are connected to?   Also, The Neutrik Hphone Jack, which side to connect the wires, I wired mine as the original Millett was pictured.   For the potentiometer, I am unsure. If i am not receiving sound, which...

Ok everyone,   Update to my project as it was a few days ago since i fried my mosfets (actually i think the mosfets are fine, they are not burnt) But i used new mosfets anyways to be safe.   My first build of this project has spanned over 3 weeks, including casework which i tried to make...

I went from a Grado Sr-80 to the beyer Dt990 (2010) and I cannot listen to the grados anymore. As far as im concerned, you shouldnt rule out the headphone based on a graph you found online. you never know how its going to sound with your particular setup.     The Dt990 with my millet tube...

Grado 225 FTW

Thanks I will definately give that a try when I rewire.   I feel like i quadruple checked everything over the weekend, because i was looking for that 1 possible connection that was screwing everything up.   But i will definately try your advice before i power up so i dont fry my mosfets...

What is humorous to me and maybe others can laugh with me, but I thought "hey, the idea of this amp is to save money so im going to use the case as a heatsink and screw the mosfets into the case".   Oops. Would have saved me lots of headaches had I known how important insulation was for...

Thanks, I will just order a new set of mosfets. The way they are hooked in the picture was only because equalizer suggested maybe the gate and drain were hooked backwards, I changed it just for effect. I believe I mentioned that before I posted the picture.   Will the heatsink pads...

Ok,   Sorry in advance for the poor quality, but i have an older 6mp camera and I am not quite sure how to take detailed stills with it. I have always had trouble. If anyone can instruct me in basic camera use, id be appreciated. Maybe then i could take better detailed pics. EDIT: in the...

so basically, I do not want to run a connection between mosfet pin 2's on each one i just want to connect them seperately?   This is because each tube is its own channel? Am i correct that the only thing connecting both channels is the Capacitor that is grounded and connects to the 33k...

Thanks for all your help equalizer.    I would post pics but i tried taking some and my old camera cant really show the detail too well. Its probably just easier to not :) I will check out the mosfet wiring to make sure they are wired correctly. the drain on the mosfet was very...

Ok,    A little update to my problems from a few days ago. I started prodding around with my DMM and found that pin 4 on one tube socket is receiving 13.9 volts, and one the other one its receiving the full 48. What connection is missing that would involve allowing all 48v into that...

Nightarya:   Your soldering job looks similar to mine and I have your problem as well. I believe if you shorten some of those wires and snipping excess resistor leads, make sure and seal each connection with heat shrink (i am using electricians tape atm) it should hopefully work...

  Quote:  To answer #3, I only bridged 3/8 but 1/4 have 2 connections running to them. Then again, my tubes light up but i cant confirm anything works just yet :)     To answer #5, I used chassis mount tube sockets to mount the sockets because they have flanges for a screw. I...

Thanks, I will try that, as fun as that doesnt sound :)   I don't leave the amp on long enough to check voltages because the tube lighting up seems unnaturally bright and i dont want to burn it out.

Ok guys,   I have finished putting together the amp using the_equalizers 12au7 method. I will post pics but im highly embarrassed of my wiring skills. Its a hot mess.   And thats probably why I am having issues, TBH. I did a little search beforehand but because I am using a different...

Doh you are right, Tomb.   After i looked at your thread I definately need to look closer at my case, it felt really solid at first glance. Thanks for the help, when I get my build close to finish i will post pics, of course :)

  Hammond 1455N1201 - Black   What is going on is that I don't believe I can wire a SSMH amp p2p if I cannot access most of the connections, it would very hard to wire most of it jamming my fat hands into the little case to make connections, etc. I was hoping to find a box...

Hey guys, I have just commenced building the starving student, I am very excited but I have already made tons of mistakes :) Its not my first electronics project but it is the first project in about 10 years, so obviously I need to brush the cobwebs out of that part of my brain. I...

I think headphones should be smooth and liquid in the midrange and highs and punchy in the bottom end. I think headphones should come with multiple accessories (I.E. extensions, adaptors, eartips, clothes clip) Soundstage is also a bonus but i could deal with a small soundstage with a...
