Hi
The only time I ever used them, it was inside the loop with an op-amp. That
probably reduced the impact of non-ideal behavior.
Getting back to the box that started all this. It’s got what looks like a
high(ish) power linear amp already on the board. It’s made up of discrete
parts. I have n

I know I have some numbers of chroma demod chips as I recall. Picked up in
a flea market special along with other more useful chips.
I absolutely have the LH033 buffers. Fet input and like lots of power. Have
used them as frequency buffers.
Super easy to use. Real chips

I remember the "Fast and Damn Fast Buffer Amp" data sheet. LH0036? I may
not be remembering the correct part number. I used to have a copy of
that data sheet, as well as another that was labeled "DC to Daylight" on
the data sheet.

I think those devices were in the same databook that had a page in the back
of the book, containing only the text
"This page is as blank as a salesman's memory"
The person who did the final editing on that issue had a rare sense of
humor.
