Grahame <graham...@googlemail.com>: May 30 09:51AM +0100 I would add P2 to David's list as they do appear on Ebay from time to time. Other P series phosphor's are hen's teeth. I did correspond with a guy who said he had an experimental red phosphor tube but I couldn't prise it out of his hands...   Another good list of P phosphors is here (and other CRT stuff)   http://www.bunkerofdoom.com/   And look under the heading CRT Focus a little way down the page for All About CRT Phosphors.   Don't get too excited by the range!   Another, different, range of colours is available using Soviet tubes. Attached is my own scavenged data. (This is incomplete, if anyone wants to add or make corrections then please PM me). Whilst a И designation (English I) is often described as green, the actual shade of green is different to a P1 or a P31. A very interesting colour combination is the B phosphor (English B). This is described as a rough, white light with a long yellow afterglow. They do appear on Ebay and there is no corresponding P colour. I like it.   My own scope clock that Nick linked is very much a "Son of David's" design using sine and cosine generators to draw Lissajous figures (rather than a Vector display as Nick suggested). The hardware is different but the principle is the same. The other Lissajous based clock that I know of is, of course,   https://oscilloclock.com/   Have fun! Keep safe!   Grahame   On 30/05/2020 01:17, John Snow wrote:

Oscilloclock <in...@oscilloclock.com>: May 30 06:00AM -0700 I was just going to suggest the Bunker of Doom site, but Grahame you beat me to it!   It tends to be a bit difficult (or expensive) to find electrostatic deflection CRTs in some of the more exotic phosphors, especially new-old-stock, but persistence (excuse the pun!!) does prevail. And as you can see above the Russian ones can be obtained readily.

Nicholas Stock <nick...@gmail.com>: May 30 08:43AM -0700 I should have been a little more specific....vector 'like' graphics....i.e., not a raster based image (even then, I'm probably not being accurate enough....) :)   In my experience P11 is more purple than blue....check out the following phosphor colo(u)rs on a 5CPx   [image: image.png]   Here's a 5CP12 in all its orange glory   [image: image.png]

Shipment delays from Ukraine

gregebert <greg...@hotmail.com>: May 30 08:14AM -0700 Latest updates for China shipments:   2 days to clear export clearance in China (Guangdong) 1 day waiting for plane 1 day transit to US 3 days to depart customs in US (Indiana)   Sometimes there are delays after customs before USPS has possession. At this point, it looks like 2 weeks from China to US, which is about normal from past experience. ---------------------------------------------------------------------------------- No word yet on my package from the Czech Republic; last contact was April 27. USPS has not blacklisted mail from .cz so I'm clueless why it's delayed. Question now is: Will I finish the clock construction before the last 2 tubes arrive ? The race is on.....

"Robert G. Schaffrath" <robert.s...@gmail.com>: May 30 08:19AM -0700 This past week I received three packets from China. Two were stuck in China waiting for air transport around April 7th (a third was last seen at a sorting center in Harlem when USPS accidentally entered the tracking number for a “U” untracked id and I saw it before they corrected the mistake). The third packet I received was sent to air transport on May 8th.   It looks like backlog is clearing.
