Microsoft Tube Amp and Speakers

Surface Computer Tube Amp and Speakers

Driven from the headphone jack from the Surface Computer.
The Amplifier consists of 2 EL-84 power tubes. No pre-amp required.
The desktop loudspeakers are my layout of a two-way front loaded horn.
The DC filament power supply for the power tubes is A/C regulated at 6.0 volts DC.

nice, but I wouldn't corrupt your creation with the word Microsoft.

as they are not reliable, forces the upgrade game.. ect.

Just listening to some The Guess Who thru the surface sound system, while I am keying in this message.... I will never listen to "solid state" ever again...

Guess I'd better keep on working on my RCA-813 project so I can have more watts to listen too.......:}

Welcome to the club
You have a very very apropiate name, as there will always be 'more amps'
Are you sure you want to go to the 813 already? It is a big step from the EL84: directly heated (10V@5A) and high voltage in the range of 800-1000V. Great valve...

RCA-813 Stereo Surface Amp

Well, I've already have an 813 project in work... I've completed the DC filament power supplies and High Voltage power supply...I had to use a steel chassis given the weight of all the parts. Because of the filament power supply requirements, I went with 6 hand wound toroidal current transformer chokes to get the dc ripple down to a value that I could live with...

I'm sure this will only be a one time build, for my own personal use for my desktop computer inside my little office at the house...Yes, it's a big project, but I've built several other EL-34 and KT-88 projects as guitar amps and keyboard amps, so this project actually would be the next logical step.....

I'm just going to take lessons learned from the guitar amps I've built and the surface amp I built, and this time do a project for myself....
