[time-nuts] Distribution amplifier for 10MHz and 1 pps

[Gerhard Hoffmann]

Yes :-) another one of mine:

It is based on a NIST design and made from discrete transistors.

Unfortunately it also needs RF PNP transistors that are slowly going the 
way of the Dodo.

Luckily, I still have a reel of BFG31.
