[time-nuts] Build my own dist. amp ??

[Dave M]

Randy,
There are a couple distribution amp projects on the RealHamRadio web site (http://www.realhamradio.com).  One has 8 isolated 75-ohm outputs; the other has 3 non-isolated outputs.  Here are the links to each:

Neither uses any of your parts, but shouldn't be unreasonable in price.

  Can I build my own 10 MHz distribution amp, using fast opamps ?
  I have searched the archives, but all of the designs are fairly complex for me to build using "point-to-point" on a proto/perf board.

  I want to feed an oven-ized reference 10 MHz sine signal (50 ohm), as a master clock for my:
  HP 3325A
  Keithley Counter
  PTS 160
  and future gear.
  (let's say, 1 in / 6 out)

  Parts I have in stock are 
  AD811
  EL2030, 2070, 2090
  CLC430
  CLC200
  LM7121
  LM6165
  Plus some LH0033 "damn fast" current boosting buffers, and some MH0007 clock drivers.
  I don't build much high-freq stuff....but a lot of audio freq stuff.
  My first thought is an input opamp buffer, branched off to separate line drivers.
  Am I anywhere near to achieving my goal ?

  Thanks.
