Dear Moderator: All what i learned buy this 60 page, is that the greek designer (if he really is the designer) exposed a common wanted project which than fall in the hands of Mr. AUDIOGURO, aparently now the owner of the project. I live in in poor country, we are 40 years in war with guerillas and as hobby i can only use scrap, what i can get hold of. So special parts are out of my reach, large condensator-banks i have to assamble by mF 4800's, whe i get most out of the cheapest.... Now, i have a scrap Transformer out of the old days, 2x12V + 6,3 V, 110VA. I would like to use it, making the 6.3V Winding the negativ feed of a 7905 regulatar, end eventually using a diode in the feed to boost to -5,6V. As i have a 35 amp bolt-on square rectifier chaep at hand, a two stage switch would be helpful to reduce execessive power to be burned of buy the 2N3055´s. I divided this project into 3 stages: 1.) rectification 2.) cheap overide stage 3.) output stage may i send You my drawing? Audioguro is some numbers to large for me, and i don't wat to be subjet of laughter. best regards, manfred, HANSASHIP
