Sphere has their "Hoods, Filters, & Bezels" page, , but doesn't include the 5000 series audio log scale screens. Given what I've seen they are actual implosion screens, not overlay transparencies.
Walter, despite not having any available (didn't expect you would), do you know the part number?
I've seen one on a scope on eBay before, and was quite tempted to attempt to buy it just for the screen. I think it might have been the last 5L4N equipped scope that was up for auction and was snipped by an auto-bidder. So wouldn't have gotten it anyway. And I think it'll be vastly more economical to make my own than deal with purchase of such a rarity.
My grand plan is to print a properly sized overlay on clear transparency that I can layer on a clear implosion shield. This place is full of old guys like myself? We all remember the days when we printed presentation materials on clear 8 1/2" x 11" transparencies, right? Foils, we used to call them. Heck, we were still using those when I started at Intel in '91. I think I've seen boxes of them stuffed in drawers in the printer rooms at work. I think all the printer rooms were cleaned out during COVID shut-down. But next time I'm in the office I'm going to rifle the drawers for them.
My hope is someone out there has a PDF with an overlay ready to go, or knows where Tek might have such a thing already. The only thing I've found is the example at the end of the audio cookbook. I did a test print of that last night. It would take a fair bit of fussing to get scaled properly. I might be better off building my own in PowerPoint or Word.
