You can overclock the BBDs without any risk to damage the circuits. They
simply stop working if the clock becomes too high. If the clock frequency is
reduced they go back to normal work again.
But if you increase the clock the delay time becomes shorter not longer !

You may use each filter of the A-100 to suppress the clock. We are working
on a dual filter (switched capacitor filter) that is planned especially for
this application.
