Final active crossover + gainclone setup297 viewsBurning the 4-channel GC and active crossover. I think this is the greatest sound quality improvement, especially for $50 active crossover. There is still hum from the new pair which I need to troubleshoot.

6T9 4.7W DIY Tube Amplifier in a Baking Pan132 viewsA Tube amp kit based on Spare Time Gizmo's printed circuit boards which are plated through, solder masked and screen printed. I sourced common components from the local electronics shop but used a pair of NOS GEC 6T9, Alps potentiometer, solid brass knob and a Hammond power transformer. The chassis is a Teflon coated backing pan ($7). The OPTs are custom wound toroidals. The amp is a little bass shy. Doubling the 100uF power caps helped increase bass.

DIY Class A Headphone Amplifier22 viewsPutting the final touches on a Class A headamp project. An IRF610 MOSFET is used for the output device and a LM317 regulator makes up a constant current source (CCS). See the DIY IRF610 MOSFET Class A Headphone Amplifier Project page for full details.Jun 30, 2008

DIY Mini Recording System24 viewsBased around the Sony ECM-MS957 stereo microphone (discontinued) and Cowon i6 mp3 player, I built a quality mic preamp to complete this mini-recoding studio. All components are high quality and excellent recordings can be made with no other equipment required. The idea is to keep this portable but to retain quality of recordings. From microphone to digital transfer provides clean, crisp, noise free recording. All battery powered the system sits easily on a table top at your local jazz club to record the music and the vibes.Jun 27, 2008

DIY KT77 Push Pull Tube Amplifier23 viewsThe second "OddWatt" tube amp project. This one is the Oddwatt 225 which will work with a number of octal tubes. Again, the driver stage is an SRPP using 6SL7 tubes and the output stage is a Class A UL SIPP using KT77 vacuum tubes.LM317 Regulators are used to provide the cathode CCS.
