[b]25L6G Tube Stereo Amplifier[/b] A work in progress. This is only an assemblage of parts so far with nothing bolted together, but it gives sort of a preview of the finished project. The chassis will be painted black wrinkle much like the transformer covers in the back. The driver tubes are 12SN7s and 6SL7s -Steve (zstrat)

NP-100v12: 12AU7 / IRF510 Single Tube Headphone Amp

2010-08-13T02:27:30Z

Here's my version of the [url=http://diyaudioprojects.com/Solid/12AU7-IRF510-LM317-Headamp/]NP-100v12: 12AU7 / IRF510 Single Tube Headphone Amp[/url], with it's companion regulator, running from an orphaned laptop power pack. I added a simple headphone output delay during tube warmup, essentially a clone of the e12 delay from Millet Max: [url=http://www.diyforums.org/MAX/MAXe12.php]http://www.diyforums.org/MAX/MAXe12.php[/url] The regulator side-kick is simply 3 50V, 1000uf capacitors before an LM317M regulator, also cobbled from the Millet Max (but without the need for the bridge diodes): [url=http://www.diyforums.org/MAX/MAXps.php]http://www.diyforums.org/MAX/MAXps.php[/url]. Works swell and no noise. Audio is incredible. Mike Y in Dallas

retro-thermionic Pinot "KiSharn" SET 6AS7

2010-08-06T17:11:40Z

Though only a small difference between this photo and the last the Pinot "KiSharn" continues to impress and compete well against commercial amplifiers costing AU$5K. I am now running it with SED Wing â��Câ�� tubes which look and sound very close to the United Electronics tubes it started with. An audibly impressive amp which belies its functional simplicity.

6AS7 SET amplifier with JAN 5R4 rectifier tube

2010-07-26T11:07:16Z

This compact amp is based on an 6AS7 (dual triode), JAN 5R4 (both coke bottle) and 12AX7 driver tube. The top plated is sprayed to match the Edcor OPTs (1.7k/8ohm). The base is solid Mirbeu. Power transformer is Hammond and so is the choke. Component-2-component wiring with no PCB. Silver wire connects gold RCAs to the driver tube. Jensen (0.22uf 630V) copper paper and oil caps join the driver and power stages. The 6AS7 are pushed to 13W dissipation. Bass is heavy and extended, mids and treble highly detailed and sound stage very deep and defined. An extremely good looking and great sounding amp.
