** In about 1978, I acquired a used BWD 141 in excellent condition.

Although capable of battery operation, a mains PSU came installed in the
battery compartment. The vast majority of units made had this option
fitted.

The custom made, wire wound, reverse log, 15kohm dual potentiometer was
the best thing about it and normally outlasts everything else. I still
have two perfect examples, one in daily use.

Because of using such a beautiful pot, BWD 141s have exceptional frequency
stability.

The typical THD is 0.05% between 100 Hz and 100kHz.


** Stumbled on this web page that has internal pics ( high res too) and a
link to the schematic.
