A Productive Day
Got a bunch of projects done that have been piling up…
1) Put in the Cabinet Sim/Boost & Speaker Mute switch for the Vox VT15, added the external speaker jack as well. What a difference! The 8″ in combo absolutely blows, now plugging in the Ragin’ Cajun actually make the amp sound half decent – still no match for true tube amp though…
2) Completed the wiring for grounded wall wart power supply that will be used by the SMPS inside the Octal Amp. The SMPS needs to be both referenced to chassis and earth ground, otherwise the amp generates very loud squelch when volume is turned pass 4-5. Cobbled together the wiring using old S-Video cable and 3-pin DIN plug/jack, so no one can plug in a regular wall wart by mistake. The amp is still a bit noisy for my liking, but when it is cranked up, you don’t hear the noise at all.
3) Back up the HTPC, I think for the first time in 3-4 years! The XP machine is rock stable, so it will be used til who knows when, if it ain’t broke, don’t mess with it! Who needs Vista or Win7?!
4) Received a bunch spreadsheets for plotting loadlines, biasing and Spice modeling from the kind souls at diyaudio and antique radio forums, we are a gang of geeky brothers ;p Now I just got to learn to use these wonderful tools.
A good day indeed!
