Ok, so I have decided to build the Millet Starving Student (mostly due to it being cheap and simple, and apparently awesome), and I need some help with tweaks. I am not a complete newb to electronics or soldering, but we never learned about amps or bypass capacitors in high school electronics, so I have some questions.
1). I would really like to get most of the parts from one place. If I could buy the caps, resistors, PSU, jacks, MOSFETs, and heatsinks from one place, that would be awesome (Tubes I can get separate). I DO plan on using high quality caps (Eyeing the Nichicon Muse series, or Elna RFS Silmic II series) and resistors. Is this possible? Because I've looked on at least 5 websites, and they all seem to carry only a few of what I want.
2). What would the optimal values be for the Electrolytics? I was thinking 470uF. Same question for the Film caps (except those wouldn't be 470uF, most likely .22uF or something).
3). I have read a little bit about bypass caps, but I am not sure how to implement one on the SS. Is it needed? Would it improve sound?
4). Is it possible to have 2 output jacks, one for low impedance 'phones and one for high impedance 'phones? Or would you have to rework the entire circuit?
5). Are there any replacements for the 19J6? It seems to be pretty rare, and I would like to maybe explore other tubes...
As you can see, I want this amp to work with a variety of headphones, because I am a starving student and cant afford different amps for different 'phones
. The sound I am going for is something with preferably NO sibilance, detailed, deep, smooth, and not overpowering bass, and as neutral as possible mids. I hate hiss, and I listen to my headphones on pretty low volume, so power is not an issue. Right now I am using Grados, but plan to upgrade to a pair of Denons or something.
Thanks for the help, and if you can think of any other tweaks that would improve the amp, by all means state them.
