The moskido schematics have changed since the last time I looked at it. Now they are Direct Coupled, using a DC servo to get rid of the large output capacitor. Apparently this new version is much better than the original version.

But this requires another pair of mosfet per channel and the heatsinks that I got are not enough to dissipate the additional heat... Guess I'll have to KIV this project.

In the meantime, I am going to convert the chassis that I did previously for the 6D10 Mighty Midget. Gonna go grab some parts later.

There are not enough audio DIY related posts... hopefully I'll update with some progress tomorrow. I need to work out the tube rectifier and also Janus Shunt regulator stages for my Mighty Midget.

While most people flocked down to Parkroyal Hotel over the weekend for the ISSE 2008, there were a handful who went to Republic Polytechnic for NoiSing08. I was there to support the event, having been at most of the NoiSings. Last year's NoiSing was also at RP. Who could have forgotten the simply fantastic horns there. ;)

This year's event was organised yet again by Johari. It's in the plans since March 2008 or even earlier. Unfortunately I was not able to bring my Moskidos since they are not completed yet. I wanted to bring the CDPro2, but there were technical issues to iron out and was not in time for the event. Hopefully in the next NoiSing, the Moskidos can be there. I brought my DIYparadise Monica DAC. The early version. I had it running on a 12v SLA battery. There were so many DACs around that I decided not to take mine out of the bag.

It's a mostly tube turnout. Unfortunately Alberto's 812A transmitting amplifier was only working on one channel. It would have been a ear opener to listen to. If I'm not sure if it is based on Shishido-san's inverted interstage designs. We did listen to it on mono with the Coral Alpha 10 speaker.

My moskido heatsinks from Aavid Thermalloy were in on thursday. They personally delivered the pair of heatsinks to my office. So very nice of them. I only managed to bring them back yesterday. What a bummer it is to realize that the heatsinks are 3mm too tall for the moskido chassis... the easiest way to fit them in is to saw off the excess at the bottom so that i can just bolt on the heatsink... Have to wait till i have the time though... Some pics here.
