I'm not sure if its always gonna be the same with every amp (I'm pretty sure it is though) but I'm pretty sure it must be turned on.

Never mind the mosfet stage, current from the signal does not flow from the grid of the 19J6, so without power applied to the tube stage, no sound's gonna come out. I believe the same applies to a transistor stage.

Is there any possible way to build this and have 2 power switches? So it could usually be a solid state, and then when I wanted to, I would flip a switch for some tubier sound.

maybe have 2 output jacks if thats necessary.

does warming up tubes really annoy you THAT much?

You have nothing to really compare it to. Just build it as is. And it won't work as a solid state, you'd have to build a separate amplifying circuit and maybe have a SPDT toggle switch between the two of them. Entirely inefficient. Just build it as is.

tbh, I really want the exposed tube look, but the sound, ive never heard, so I'm not sure if I'd even like it.


I say take the Literally the 3 seconds it takes to turn it off and don't forget.
also don't forget to keep that finger in top shape because if you don't you might get hurt flicking the switch. LOL
even if you had 2 switches you would still have to flick it on and off every time.

I work that finger out daily to prevent freak accidents like those.
I think I may just go for a solid state since I'm so used to just putting on headphones and listening.

your being a little ridiculous man your giving up trying something new (that you might really like) because you dont want to have to turn something on and off

Its not that at all. I'm on an extremely tight budget. I was simply wanting to know a bit more about this to figure out if it is what I need RIGHT NOW.

I have no doubt in my mind that I will end up building one of these. Just after all my questions were answered, I realized its going to be a bit further down the road now.

To add to my questions and complete knowledge-ness about this...
Are tube amps biased towards any certain type of music, or can they produce good results for, say, gaming?

AHHHHH... ok sorry. lol. I was gonna say a switch is a bad reason not to get it.
Cool have fun with whatever you get.

I replaced the Panasonic 470uf caps with 100uf Muse ES Bipolar caps.
I was able to lower the cathode resistor to be more like 5k ohm, maintaining the same sound sig that I liked and keeping the gain under control.

These Muse Bipolars really do sound quite good, more detailed than the larger FM's did while in the same position. That proabablyhas mor eto do with being bipolar and smaller than anything.

As we speak, I am using this amp with my 9.4ohm IEM's and the hiss is very small to say the least. I seriosuly need to make an impedance adapter because this amp sounds superb with these IEMs. No noise whatsoever with 32ohm headphones either. I will get around to getting some proper resistors to get graphs, but I have a feeling that it will be pretty similar.
