• WARNING: Tube/Valve amplifiers use potentially LETHAL HIGH VOLTAGES.
    Building, troubleshooting and testing of these amplifiers should only be
    performed by someone who is thoroughly familiar with
    the safety precautions around high voltages.

Unhappy with the Lilliput design

OK...Altro canale sounds like other channel, so PS filter voltage drops probably are for two ECC88's and I should double-check my math. I think I overlooked that with my phone calculator first analysis.

I am reading the transformer secondary approximate 'need'(or available to builder) as 180 vac 300 mA with similar current rating for 10 H filter choke...but S/10 is still a puzzle for me. Maybe S is first letter of an Italian word that was in the original article.
