Glenn for your info: Thomson Grass Valley uses AD8055 amps in their recent analog distribution amps, 1 loop-thru and 8 outputs (with 4 x AD8055 and 2 outputs per ic @ 75 ohm), modifying to 50 ohm seems to be straightforward. These cards are not yet out of production, they are still being used for all kind of "glue" applications, eg. sync, de-embed_do something like add audio_re-embed, etc. and this in, for the rest, full digital installs SD or HD. The circuit does not seem to be complicated, didn't look at the schematics yet but the power-supply seems to be well filtered. Model nrs. are 8901, 8902, etc, the board is not that expensive but they need to be put in a "Gecko" frame = means very expensive... BTW: all Pro Broadcast equipment is made of pure gold you know ;-)) I'll try to test this card with some decent 5 or 10 Mhz signal (I'm still waiting for my T-Bolt from TAPR...). http://www.grassvalley.com/docs/Ordering_Guides/modular/gecko/MOD-1014M-2/8901.pdf
