There's one ECL chip- an MC10116 which is a triple differential amplifier. The datasheet says that if any of the amplifiers are not used, the corresponding input must be tied to the base bias output.
Hi Thomas, nice piece, I like the light of VFD displays, I heard that you used Kontakt 61 and air for cleaning. I have been using Kontakt chemistry for many years, but 61 is the last part of (as I call it) the holy trinity - 1) Kontakt 60 - dissolves dirt and oxides, 2) Kontakt WL - rinses dirt and K60 residues, 3) Kontakt 61 - creates a protective film on the treated contacts. Depending on the contact material, for gold-plated contacts I will use Kontakt Gold instead of K61. I also have the digit extension on my small programmable counter that I use as a monitor for a Tektronix oscilloscope for audio equipment repairs, it is Wolf's design - a four-digit counter extended by one place - it is enough for an approximate reading. Nice day 🙂 Tom
That is a nice display!

If you look at R&S spectrum analysers they often have a grounded microfine copper mesh covering the display.
