I couldn't help doing the Edison label, just couldn't resist.
The fan shaped thing acts a cradle for the Bluetooth device the listener is using (I pod, I pad,smart phone etc.).
The ... um...er...'tubes' on the left make up the display of the pnp/npn color organ.
It looks cool, and sounds very good, no hissing, hums, defined highs and non colored bass.
The sound on the video is awful but in real life the sound is sweet.
Here's a link to the video to see the Jules Verne display in action....

Long story short. I have been a live sound engineer for the last 37 years. Never really had a decent stereo, never turned the radio on in my truck, never plugged earbuds in to my phone. Sound is my career, my job. Big point source boxes back then, mostly line arrays now a days. I know how to listen to that. Don't get me wrong. It can be very passionate, very personal, but I kinda forgot about the music. Got in to diy stuff a couple years ago. Built this amp from Pete Millett. Great pcb, bom, advice. I've "listened" to more music in the last week than in the last 10 years. So how does it sound? To me, perfect.

It's hard to beat single end tube amps especially SE UL pentode amps. Just my opinion guys. Though my main amp is an imposing 300B SE ($4K for parts alone) when recently I built an EL34 SE UL I realised how much closer the music these simple amps can get. My 300B SE (Silver Dragon) almost has too much detail which can be a little distracting while listening. As I said, just my opinion after 46+ years of DIY audio. Here's an image of the Silver Dragon (PS separate and not shown). The power tubes are TJ Full Music limited edition carbon plates.

The original schematic has been around for quite a while and I built two of them. Virtually takes any tube: KT88, EL34, 6L6, 6V6 etc. But I asked guys on the diyaudioprojects forum to tweak the original. The posted schematic here is the result. I only used EL34 tubes in it in UL mode. A friend who had a number of Chinese PP amps took one listen to my amp (retro-34UL) and bought it on the spot. I wasn't intending to sell it. I'd only had it a week. The PS design is mine.

I just assembled two of Oatley Australia's latest iterations of their famous headphone amps the K272C. Separate filament and B+ batteries and battery "health" LEDS for each. Now the kit comes with an OPA2134 chip. Better bass, better sound. The ABS plastic enclosures are Al lined and wire-wrap wire is used in the signal path. Switched 6.5mm phone jacks and power switch ensures little chance of leaving it on when not in use.

Forgot to say thank you for the schematic. I will be bugging you about it in the future.

I would like to say they are resonance dampeners but they aren't. They purely ornamental. They are chrome draw knobs. Who knows maybe they do dampen resonances??
