old Philips caps from Holland factory and German Roederstien are my favorite for filter caps and cathode bypass caps.
I cut the aluminum cans and put Philips caps inside of 70’s Sprague paper sleeve caps.

Researchers at the Massachusetts Institute of Technology (MIT) and Harvard Medical School have teamed to develop a novel tattoo ink that can show your body’s health changes.
The novel ink consists of biosensors that react to changes in the tissue fluid and make the skin an “interactive display”. So far, researchers have investigated four biosensors that respond to three types of body information, changing their colors.
As the pH-value increases, the color changes from violet to pink, an increasing sodium content is seen as a bright green under UV light, and blue becomes brown when the glucose level increases.
This animation from a video of the researchers shows how such a tattoo might look like: 
Especially for diabetics, a tattoo with ink that reacts to an altered glucose level could be useful. They have to prick their finger with a small needle if they want to measure their blood sugar level – usually several times a day. This procedure can be painful in the long run and can lead to small scars.

didn’t know Jensen had Concert series with ceramic magnets. this PM-1002 sounds more like Jensen 10J11 than WGS Veteran ceramic to me. even I believed it was an alnico speaker when I grabbed this off ebay for $69 plus shipping. then googled what Syntox-6 was after a week playing this in my 5F1 project. a bit disappointed while figuring out what the magnet was. but still happy with this NOS Jensen with the original box. and it is way louder than Jensen 10J11 alnico speaker as I expected.
I’ve tried Mullard and a few different 12ax7 tubes with it. and going to stick with GE black plate 5751 for a while.

this switchcraft black plastic plug looks always nice to me. especially with vintage Jensen speakers and tweed amps.
I recently noticed the material and the shape has changed through the years. I’m not sure with the exact timeline but, the first and second left ones look a bit older with the different shape of the end tips.
the first one on the left looks like the oldest brother. it’s the one for my 5D3 with P12Q now.
the next one came with 1953 tweed deluxe 5C3. the rest of them look like came from 60’s or 70’s production. I’m just guessing. I’m wondering when they started to put the nylon spacer not bakelite.

One of the most interesting things about DNA is that we have discovered, in humans, the 3% of the code which builds our physical bodies also has encoded within the bodies of all of our ancestors. We can switch on these old systems (in animals of course since this would be highly unethical to do to human beings) and give a chicken teeth or scales. We are not just us. We are all the physical forms in our lineage.
Now, that accounts for 3% of our storage. What of the other 97%? It is memories. Now the skeptic will go “yeah right Mr. Science”. Hear me out here though. Why is it so hard to accept memories encoded into the helix? In fact all “instinct” is encoded memory. What beach to lay your eggs by the light of the full moon if you are a tortoise. Where to migrate if you are a starling or a monarch butterfly. Sharks even have maps of the magnetic markers on the seafloor. None of this is learned. It is there at birth.
There is a very good evolutionary reason for this. Rapid adaptation. We have a repository of past experiences so we do not have to reinvent the wheel every time our environment changes. Human beings have noted this for at least as long as we have records and this has given rise to theories of reincarnation which appeared in nearly every civilization on Earth. Science has resisted this because it sounds too “supernatural” in the same way they resisted the “Big Bang” because it sounded too much like creation. Yet, it is anything but supernatural. It is entirely natural and the only explanation which makes any sense.

[EDIT]
I’m updating this post not to make people confused. I believed B+ was lower with 5v4g than 5y3. but 5v4g is increasing B+ and makes the bias warmer than 5y3. I guess it is the reason I feel the amps are more alive with 5v4g
then I noticed the vintage amps with the original caps from 50’s and early 60’s are more vulnerable with 5v4g to 60hz hum. I’m just guessing leakage of the coupling caps and the filter caps could be the reason. I’m still enjoying 5v4g with the amps with new components. didn’t have an issue with my 5D3 which has new filter caps either.
[EDIT again]
one of my 5V4G tubes shows very low B+. the 60hz hum came from it I believe
there are more and better info for 5vg and 5y3 rectifiers on the gearpage.net
I hook up tweed champ, deluxe, and m-track 2×2 together while jamming with youtube. 5v4g sounds still alive with this stereo and digital setup to me. but, m-track 2×2 is cheap and sharing the one single full bandwidth with usb and instrument at the same time. it sounds good while using only one of them. it sucks when the knob is at the center.
it’s the knob on m-track 2×2. don’t buy it if you want to use your guitar amps as monitor speakers while playing guitar through the direct input. maybe I’m just doing this wrong.

Tecumseh, one of the greatest men ever to be born on the American continent. A Native American, war chief and statesman he was essentially a Native American George Washington. He saw his family killed by the white settlers and the soldiers of the new United States of America yet he refused to kill women and children.
Among the tribes, there was no concept of Indians as a group i.e. you were a Shawnee or Mohawk, not an Indian. Indeed, even the whites were seen as “tribes” the British tribe, French tribe, Spanish tribe or, worst of all from their perspective, the American tribe. Tecumseh was a visionary and envisioned a Native American confederacy from the Great Lakes to the Gulf.
He sided with the British in the War of 1812 only to be abandoned after the end of the war. Abandoned to the Americans who destroyed him and his people.
Please note: No nation is all good or all evil. One must acknowledge the failings as well as the successes of a nation to truly understand it.
