This is my version of the low-z amp originally designed by Terry Fritz.
It employs a LM12CLK op-amp and is supplied by a custom wound transformer.
I added the tesla coil tuner suggested by Terry Fritz and
the tesla coil tuner after plans from Antonio Carlos M. de Queiroz.
Both are powered from an extra winding I added to the power transformer.
On the front panel the two knobs for adjusting the frequency of the two
tuner circuits, the indicating LED located inside the frequency scale and
three BNC connectors can be seen. These are the two output signals and the input
for the low-z amp. This way I can feed either signal into the amp or use
each device with external sources or loads.
