Hi all,
I have bought from a fine seller a new PSU (42V, 20A max). Look at www.test-measure.co.uk It is all new, perfect working and low cost. No problems with the seller.
He sells also in www.ebay.co.uk (where he is 'snibbo') a very fine working oscillator (the LDO 100) that has THD <0.003% from 20Hz to 20kHz, 80kHz bandwidth.
I have bought both from him at very low cost, and other instruments too, that he is now selling with the greatest satisfaction
I share these informations with all of you as my friends in diy.
Best regards
rephil

Hi all,
I have produced some FFT plots of the sine produced by the LDO 100 oscillator at frequencies of 100 Hz, 1 kHz and 10 kHz.
They look good
The load was 600 Ohm. In was at 1Vrms, this is 0 dB on the plot.
