e, sad i ti inzinjerski nastupas ....... ubi svu zabavu

pazi da se ne polupa, ako se prevrne

da je i vladd napisao nesto na englenskome, poceo bih da se zabrinjavam za sebe ......

lako ti je, kad imas Al Qaeda cameru

few funny pics more conclusion - all 3 iterations (2N1099, 1T813, 2SA1491) are fun to listen, sharing same holographic quality, which is most probably result of extrafunny THD Spectra

same, 4R Load

Final Old Soul installment Old Soul B or Bip, whatever instead of Ge Bigun, plain and common Si Bigun All changes needed are - replace part and replace shifting resistor (R122( value from 10R ( adequate for Ge Ube of 180-2--mV) to 22R ( adequate to Si Ube of 650mV), as part which defines current through Level shifting small mosfet M101 Had few 2SA1943 mounted them , fired up and Iq was sorta same as set for Ge - 1A-ish started upping Iq and fine-tuning DC Offset , did one channel and when I'm almost done, 2SA1943 in that second channel stopped pretending, taking R122 and output mosfet together with him, most probably South Ok, power down, remove both 2SA1943 , replace R122, replace IRFP240, mount undoubtedly and certainly original 2SA1491 power up, set what is needed , let it cook for a while and here it is - same wakoo shape of THD Spectra rails as before, Iq increased to 1A5 Load 8R

najsigurnije kad u sumu ides peske, samo sekira u ruci al nekako se naucismo na prekidac mjku mu, ni drva nam ne trebaju ....... a sta mu je danasnji analizator, nego ultradobra i skupa muzicka kartica?

ne znam kakvih zamerki imas na proceduru, al meni dobra dovoljno dokazano ihaj puta - ne merim do 300KHz nego do 20

ARTA, nije RMA

ako je po IMDB, racunaju joj 4

e pa drugo je JJC on se podrazumeva

Listening same holographic sense as with 2N1099 everything else, in short: -sense of organicity is there, which must be first quality, considering nature of gain aparatus and lack of overall NFB; so, didn't spoiled that -mellow, then I tried to observe sense of speed - no lack in that department, too -Freq. extremes - have no objection one of my fave albums - see pic - besides MZM liking music on, it is extremely nice tool - spaciousness is exquisite, nothing overproduced or over-edited, and Mile's trumpet is full and detailed ( which isn't the case on some other recordings) but - one thing especially useful - in enough places, M. trumpet is blasting to the roof, and any weak link in amplification chain ( and yes, even speakers) would run crying in these moments, while you have ears bleeding well, no with these boring amps .......... aggression of trumpet sound is here, but green is wide, observing that I'm still in same room, and no bleeding ears

4R load

THD, second channel 1T813 just to be sure that there was no heavy weed yesterday, neither for me nor for amp, I made measurements of second channel didn't bother to match Biguns especially, except with universal measureitallthingie, afterwards Hfe and Ubc are confirmed as similar in T-Bed 8R load same Wakoosness as first channel

eo se zakaci malo na JJ

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

pa, tebi najomiljeniji

4R load

checked trice entire setup, done each step at least twice, when seeing how THD numbers are weird 8R load

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

onda mozes da nastavis, da malo razveselis - sa GG a posle toga sta dohvatis sa J. Hiseman a vece, za lepo i lagodno spavanje, da se ostane na Ostrvu a ne more prog - najomiljeniji Wishbone Ash

to da se ima, po nahtkasni?
