Hi!

I was looking thro' the design of the Russian "GO" RLC–2 RCL Meter and noticed this uses a  MAX293 "8th Order Elliptic Filter" device to generate the two quadrature sinusoids for the test component, so this set me thinking – can the same approach be used in a D.I.Y. Huntron Design to generate the the 50Hz, 400Hz & 2kHz Component Test Voltage, then fed to a Power Amplifier and a small 100V Line Matching Transformer used in reverse then on to the rest of the Huntron Circuits that select the Test Voltage?

It's an enigma that's what it is!! This thing's not fixed because it doesn't want to be fixed!!
