I would hang onto that Dahlquist unit. That's a nicely conceived unit and could come in handy in the future.

Good point Dave. That's why I still have the DQ-LP1! I kept my copy of Frank Van Alstine's plans for his upgrade modification to it. One thing to do is just not use the high-pass inputs---the capacitor is uses for filtering can just as easily be installed on the power amp input jacks, saving an extra set of inter-connects. Then use the active 3rd-order low-pass inputs only. That control has an adjustable frequency range, though not nearly as wide or precise as that of the First Watt B4.

Well, it's hardly going to make any difference unless you have interconnects that are a mile long.
Installing the capacitor internal to the DQ-LP1 is preferred as it allows to use the shunting resistor location so you can fine-tune while still using standard value capacitors.
Dave.
