Holy.... Crap..... Absolutely stunning work, AMB.

Most impressive, Steinchen...

Switching power supplies have a lot of high-frequency noise.

Tangentsoft Go to the Audiologica and Electronics sections. There's quite a bit to read there, but it's quite well done. If you're interested in building amplifiers, I recommend the Chu Moy link within Audiologica.

You should be more than fine with +/-12V, especially with line-level signals.

I'm actually really interested in obtaining the power supply (I'll buy it now if you have boards). If you ever do implement an LCD screen and remote control for the volume control, I'll put down cash for it as well. I'm interested in replacing the welborne attenuator in the preamp section of my...

I'm pretty interested too. Any chance it'll be remote controlled in the future with LCD display?

franky, I love the case! A mix of modern aluminum with tubes.

Do you have a schematic of the circuit? If it's a non-inverting amplifier, there will be (assuming it's a CMoy) 2 resistors that determine the gain of the amplifier. One goes from the output of the opamp to the inverting (-) input of the opamp. The other one goes from the inverting input to...

Absolutely gorgeous work. Beautiful blend of wood, aluminum, and acrylic.

I implemented additional upgrades to the power supply section of the preamplifier section in my DIY integrated amp: I added numerous capacitors ranging from 0.1uF to 1000uF to the post-regulator power rail (two TREADs create a +/-10.77V DC power supply) and added 2x 3.32K bleeder resistors...

Extremely impressive figures. I really like the slew rate of 290V/us. I'll be looking into this in the future for sure.

What effects does bypassing signal capacitors in the input stage of an amplifier have on the signal itself? I'm asking because I'm considering bypassing the 4.7uF Panasonic film caps on the input stage of the power amp I built with Obbligato film capacitors. Thanks ahead of time.

I used a 530VA Avel-Lindberg toroidal transformer.
