2SK1058-SE-Mosfet-Amp.jpg2SK1058 Single-Ended (SE) Amplifier7260 viewsThis Class-A power amplifier with zero negative feedback and 5W output audio power was built based on the schematic of the DIY Class-A 2SK1058 MOSFET Amplifier project by Mark Houston.
The amplifier uses a custom handmade choke coil.
The power supply uses 4 x 15000 µF Towa capacitors designed for Adcom.
Two large heatsinks and one 88mm fan provide enough cooling to keep the temperature below 60°C.
The amplifier is used with custom made sensitive acoustics.
The sound is very precise and detailed. It has deep sound staging and amazing microdynamics.

Ion_DIY_2-Way_TMM_Tower_Speaker.jpgIon - DIY 2-Way TMM Tower Loudspeaker7260 viewsThe Ion tower loudspeaker project is Adam's latest diy speaker project. The Ion is a 2-way speaker in a TMM configuration. A Tang Band 25-1372SC 1" inverted titanium dome tweeter is used along with a pair of Audax HM170CO 6" woven carbon fiber woofers.
The Ion speaker project will be a very challenging build but Adam notes that it comes with a huge payoff! The Ion tower speakers have quickly become Adam's favorite loudspeakers.
For the full project details, see the Ion - DIY 2-Way TMM Tower Speaker Project.

1_phono_pre.jpgKit form Phono Preamp7253 viewsPaul's rendition of the MM Phono Preamplifier Kit is both neat and very serious looking. The small instrument case matches a 12AX7 Valve Amplifier of mine that Paul is now using. Paul, like me is very pleased with the sonic qualities of this inexpensive phono preamp kit. He did note it took a day or two to sell to a smoother sound.
