I think there may be some confusion due to similarity of names.
Extron apparently makes or made video gear.
Efratom made Rb sources and precision frequency distribution stuff.
I'd like to find info on the Efratom distribution system, and
specifically the "MBF" modules.

I have a Hitachi VD-1000 video distribution unit that's been sitting

I have used the amplifiers for years. Good grade GVGs and extrons. They
just work.
Though like everyone I considered shifting to 50 ohms it never seemed worth
the effort.
In fact most of my distribution is 75 ohms.
Cable and connectors are cheap well shielded and easy to install.

I have a few of the 2 in 5 out video distribution amps. I took one apart
and converted it to 50Ω from 75Ω, and to be honest, I can't really see a
difference.

Hello Taka,
As long as you stick to CW sinewaves *and* the distribution amp specs are
honest when they say "buffered out puts", the problem is fairly simple. If
you're not seeing distortion under your operating load and signal
amplitudes,
it's OK and I'd not bother to change anything.
By
FWIW, I've been using an Extron video distribution amp for almost three
years now, bought with the intention of modifying it to 50R but never got
round to it.
I've never been able to identify a practical reason to change it because
it works perfectly for my needs though I'm sure others will
