I'm too impatient, I just wack in some cheap headphones and listen
A couple of questions. Would 63V 220uF Nichicon Electrolytic caps (Mouser number 647-UHE1J221MPD work for C1, C3, C5, and C6? And is there a decent alternative (or maybe Im missing it) to C7/C8 on Mouser?

Hello!
I'm now finished with my build, the tubes are glowing, but I still haven't put my heaphones on it: I found a really nice post from the_equalizer about testing your amp, so It doesn't destroy your whole setup
Here it is: http://www.head-fi.org/forum/thread/319231/millett-starving-student-hybrid-amp/3870#post_6032606
I've got some questions about it, more precisely about the different voltage test:
- How do you measure the voltage at the tube filaments
- How do you measure the voltage in the Output Jack? Do you plug in a Mini to Mini, and measure at the other side?
- How do you measure the voltage in the Jack Plug?
Thank you very much, I'll post some pics!

Curious, does anyone know how this would pair with the DT990/600? I'm considering trying to build one as a relatively cheap summer project to burn time and get an intro to amps as well. Other option I've been looking into is the CK2III.
As someone else posted, the risk of DC at the output jack is minimal, due to the capacitors. Still, you could get a defective cap or have some serious miswiring that puts DC at the output
If you forget to add the 2K resistors right at the output (R6,R12) you get ~12.5 volt DC at the output. Been there, done that...

Yeah. That would qualify as a serious miswiring ! So how is your SSMH doing Beftus? Tried different tubes? Has it burned-in nicely?
