Hello to all,

Thank you for this schematic, i guess it can be improved, mining the zener which is very noisy and in that place one capacitor 100mf and one 100nf in parallel connected in collector of Q203 near the collector and "0" voltage, is a countermeasure to that noise, or better change it whit a stabilizing IC. To bad image there, i can't read the value and name of components, if someone have one better please post it again. Thank you, and best regards. Pandoraguru.
