Hey guys,
I have a friend who wants to build a dedicated headphone amp for me, based on two 417a as Pre/Gain tubes, and two 45 for the output, they are intended to suite my low impedance and high sensitivity Audio Technica cans. (W11PN & W5000).
He has some rectifier tubes in mind, I forgot the model name :/
What do you think of this combo and particularly on the 45 tube as output ?
I would also like to know if you know any amp that uses the 45 as output tube, there are probably some for speakers, but I wonder if there were any for headphones
I remember there is a 300B amp, which his quite exclusive, or am I wrong ?
My guy is a true tube guy who is mainly influenced from Sakuma and Kundo from AudioNote Japan, he plans on utilizing as much transformers as possible and as less caps as possible (sakuma style).
He likes using 300B and 845 tubes but he said the 45 is more linear but has 1/3 of the 300B output, therefore is great for headphones (which requires a low wattage) but not that good for speakers.
The amps is planned to cost around 1300$, the cost is mainly parts cost.
I got too much into technical, which is not my strongest part, I leave it to my friend
I would really appreciate your comments.
Thanks
