Just uploaded a short (6 megs) video of a BC-348 which is totally dynamotor stock, feeding a 600-ohm speaker. Full volume with the pot at 2 o'clock. http://home.netcom.com/~arc5/BC348/BC348loud.WMV The period-appropriate music was a happy accident :) 73 Dave S. p.s. The BC-348 has been cleaned and "cherried" since this was taken.
