Stereo Micromitter needs a boost


For a start have you removed the attenuator on the output?, it's designed to keep it legal in Australia - so removing it will make it illegal (it's already illegal in the UK!).
 
have tried this

I just tried this and have found that this has helped but, on further checking and going over the setup proceedure I have found that the maximum I can get out of TP1 is 0.76 votls dc and not the stated 2 volt.

any ideas?
 
the other thing I am not sure of is the 68nh and 680nh coils, the ones supplied are surface mount, and bloody microscopic. but I don't think that would affect TP1 test.

Does your voltmeter have a high input resistance?
Does the DC voltage at TP1 rise and fall as L1 is adjusted?
Are the switches set to a frequency in the chart?
 
micromitter

Multimeter has high input resistance, and by turning L1 adjusts from 0.43 to around 0.77 volts.
