no idea what 707's are worth nowadays, i have not seen/owned one since the mid 80's,
yes they work ok on 11mtrs, the ft-707 and its twin sommerkamp ft-767 were popular for use on 27mhz freeband here in the 80's,
we used to change the 10mtr A and b crystals, peak the oscillator coil for each new crystal and you were good to go once you got used to the frequency display reading +/- the offsets on ssb,
707's use a pair of 2290's in the pa and need around 19amps for 100w output.
