imam ( negde su i na slici) P210, nekih 10-ak komada ali mi mirise da su malo problematicni po pitanju temperature na 25W disipacije a manje od toga nece da ide

Did mount 1T813 today, in place of 2N1099 fired it up, it set itself exactly at same Iq (as previously 2N1099) , did just minor tweak of output offset same situation for both channels - everything perfect in static state then connected old crummy Sigene to input, scope to out, no load, just to check does modulation reaching output first channel OK second channel - started , and somewhere at half ( of max) thingie just went South - speaker DC protection dissengaged relays, got 48V across 0R11 resistor group ( where I need to see 110mV) powered it off, logical check - dead mosfet, dead Ge, two 0R22 resistors dead ( there is a reason why there are 2 or 3W jobbies) was it 1T813 Dud ? most likely ...... and now I'm thinking what and how to test them if I decide to get them in quantity it seems test with actual load, fastest way of Ge tossed in 1L container of demi water is easiest way to do it anyway - replaced what's Dodo, checked rest of circuit and fired it up again this time everything went good, so did tried both channels with load, up to clipping

Moje pukotine na displeju izgledaju još strašnije
