Almost-complete… Just needs the top panel fitted.
(Click for huuuuuuge image…)

Two things accomplished tonight… For one, the Millett Hybrid Max headphone amp I’ve been working on seems to be working consistently. I still have to get the top cover fitted and make some custom cables, but that will all come after I’m certain the bias is stable.

As of right now I’ve got it running at 27VDC with each tube biased to 13.5VDC. The bias for the MOSFETs is as close as I can get to 200mV, and it’s all sounding good. I had it hooked to my crappy Yamaha player earlier and it was sounding good, but when I hooked it back up to the Playstation (as seen last night) I couldn’t get the PSX to read discs any more. I think the laser on it has gone, just like they did in so many others.

I’ve only owned it a week, but I sort of expected this. I’ll try and pick up a new transport and at the same time do some work on the audio out circuit. I may even hack up a controller so I can have Play/Pause, Stop, Next, and Previous buttons located on the top of the case.

Tomorrow I’m also going to try and get things set up so I can listen to chiptunes from a MIDIbox SID-NUXX on it.

Oh, and a few more of the decent inside photos showing the wiring for the various connectors and top panel and such can be seen here (photo gallery retired), if you are interested.
