Western Electric Company No.91-A

The 91-A is possibly the most copied WE amplifier. This amplifier started production around 1929. The fact that it is still being made and modified today says volumes about their engineering feats. I am curious how this amplifier works in todays world. It would seem to me the bandwidth would be somewhat limited by todays standards. From you guys who are familiar with this amplifier I would love to hear your opinions.
