175W DIY Solid State Amp Kit3172 viewsThough this amp is designed as a hi-fi power amp with very low distortion figures, I use it as a guitar amp due to it’s high power. The PS is rated at 500VA. It plays extremely loud and can deliver nearly 200W into 4 ohms.

Zero Component Amplifier - Single MOSFet SE Class A4182 viewsThis is another shot of the ZCA. It shows how the PS and heat sink all fit into one good looking case. Most of the heat is generated by the load resistors which are forward of the amp and line-up with the breather holes of the case. For more information, see DIY Class A Mosfet Amplifier Project page.

DIY Class-A Single Ended (SE) Amplifier with 2SK1058 Mosfet3006 viewsImplementation of Mark's DIY Class A 2SK1058 MOSFET Amplifier Project. It was difficult to obtain good 10W non-inductive wire wound resistors, so a 12V 20W lamp was used in place of the load resistors. Like in ZenLite Amplifier. :)

Here is a link to more pictures of the amplifier.
