The decorative rings arrived. I fitted them to the chassis mostly to cover the poor drilling job of the holes.
These rings have 54mm outer diameter and 36mm inner diameter and are about 10mm tall. One thing of caution - they make installing and removing the tubes much more difficult because they get in the way of grabbing the tube base.
Still another rainy day.
Here with DHT. Shortest distance between tubes is 0.3 inch. This built was not intended for the huge triodes…
...but it is a good sounding thing.
No, was traveling to our contract manufacturing sites in Shenzhen and Zhuhai frequently for work. Laowei (or laowai) is Pinyin Mandarin for foreigner/stranger/any non-Chinese. I'm a blue eyed, blonde haired, fat old American guy.
Back when I last worked in a cubicle environment (2010), I found that ear buds (PK2) worked well for me. The music was not audible to my neighbors. I was isolated well from normal room noise and yet could easily deal when somebody wanted my attention.
Edit: Please note that I had music playing all the time.
I spend about 4-6 hours of my day at work with my ETY's in.. a lot of the time with nothing playing. I am a big fan of isolation, and I know that IEMs are not for everyone, but they do the trick.
(in they go -> goodbye cruel world)
I got involved with noise cancellation at one stage
US5018203A.pdf
In the late 80's noise cancellation was in its infancy. So while I was working on that I found that Dick Rutan's round the world Voyager airplane used noise cancelling phones. So I phoned them up in the Mojave - and instantly got through to Dick Rutan. He told me that they were using an experimental Bose system, but that they broke around ten hours into the 9 day flight.
I also had a natty idea for enhancing the sound attenuation of double-glazed windows. The idea was to sense the sound pressure inside the cavity and use a transducer to servo that to zero (or as close to as possible). But a patent search revealed that someone else got there first. But no such system has been made available to my knowledge.

I personally don't find that any full-sized headphones isolate enough to be useful in terms of noise reduction so for non-IEMs I'd say active noise cancelling is the way to go.
I love how half these teams' overall strategy is to just cycle through star after star, somehow hoping they can catch Golden State with rag tag crews. Makes me appreciate Boston and Philly willing to nosedive for multiple years to try and assemble an intentionally devised team with actual focus. Please Chicago, please do this.
Guys like Howard, CP3, Melo... I just don't see it.
