[time-nuts] 10MHz dist amps

[Tom Knox]

Hi John;
Amazing product, I did not realize you could use the TADD-1 for 100MHz distribution.
I do have a question, as someone who has tested most of the commercially available distribution amps on the market TADD-1's -140dB @ 1Hz is among the very very best best in the industry, (nothing is close for the price) but compared to the very best the noise floor is a bit higher. Is this simply a result of a raw board instead of a shielded enclosure?
Thanks;

Tom Knox

FWIW, I designed the TADD-1 to have equal length signal paths for all six channels.
