Re: Up to date capacitor list for Tek 2465A and 2465B scopes (2018)
Google Sheets (https://www.google.co.uk/sheets/about/) is fairly good for that. Overleaf (https://www.overleaf.com/) is good too, though you define tables in LaTeX rather than a spreadsheet per se.

I understand that the Tek2235 wants a 154-0861-00 CRT, which seems to be made of Unobtanium. Are there any known substitutions? Are there any _available_ known Substitutions? Thanks in advance! 73

Fabio mentioned some difficulties in aligning the text onto the button faces. How about maybe adding guidelines or some kind of extra markings around the texts to help cut out the physical transfer

Re: Tektronix 453 Power Indicator Bulb needed
I get that, but the lamp is still a consumable that will wear out again. How much extra work would a LED specifically be? (I own a 453 fwiw)
