Yes it works.  I just bought what at one time must have been an
expensive six channel pop amp powered video distribution amplifier.
I opened it up and inside are six video op amps one for each BNC
connector.    I checked it on the scope and it works for 10MHz but not
any higher.    There is room to hot-rod it.   The op amps are spec'd
for +- 18 volts and are only being run at +-5.  I'll modify it for

Analog TV has become toxic waste and you can get things like video
amplifiers for just over the cost to ship them.   I bought this 6
channel amp for less than $1 on eBay.   I was the only bidder.  I
always check online before I buy something like this for schematics.
This amp was made in the US and the manual and schematics were
on-line.   This like this are available all the time
