Of course, where I wrote "...the maximum signal that...", I meant to write "...the maximum *frequency* that..."
Sorry for the inaccuracy.

Recently, I acquired a 7B92A that in contrast with the unit that I had, turns out to have no (discrete?) tunnel diodes in the trigger circuits but instead, uses hybrids packaged like the ones in e.g. a 7904A's vertical amp. I have seen references to this newer version of the 7B92A but haven't been able to find any description of the reasons why and any possible consequences. I would guess (and could appreciate) lower cost, higher reliability?
I wonder whether the circuits in these hybrids still contain circuits with tunnel diodes or do they contain more traditional circuits and if so, are there any functional differences? i could imagine that the maximum signal that the unit will trigger on would be lower than the tunnel diode-equipped version.
I would much appreciate if any of you experts could shed some light on this.
