    Hvala Da li se mozda ima informacija kolika treba da bude mirna struja?

    da li neko zna cemu sluze ovi trimeri? da li je to za podesavanje DC ofseta?

    vrati da bude tako, samo okreni kond i proveri da li su oni redno vezani otpornici 790K zajedno

    da li si izvukao dobar otpornik od 2M, posto imas dva komada u jednom kanalu izvuci otpornike od 2M i 3M ,to su onda dva plava otpornika pored 0,1uF i prespoji 0,1uF sa 100R otpornikom

    a ovo je Thorsten RIAA obrati paznju da su ovde vrednosti 100pF i 330pF i 750K u RIAA kolu

    Ako si radio Roberth RIAA (C6=100pF i C7=270+33pF) onda treba ovo da uradis: The 680k and 110k resistors are in a series in the 750k resistor position. The 270 and 33pf silver micas are wedged in the 330pf position in parallel. The 110pf silver mica has been replaced with a 100pf silver mica. The 2M and 3M3 resistors are removed entirely. They do not require bridging. The 0.1uf capacitor is replaced by a 100 ohm 1/4W carbon comp. resistor. The Elna Silmic 2 100uf 16V capacitors are placed in their positions- take note of polarity. The second 2M resistor that was located above the 2.2K resistor has been replaced with a 680k resistor. Note on the 2M replacement resistor: This area may effect bass response under 100hz with certain tubes. We are working on a solution to this, looking at more tube data and may have a recommendation of either an optimized value for the tube you are using, or a variable resistor which you can adjust if you do a lot of tube rolling. The general consensus is: 680k for NOS tube examples 2M for new production chinese examples 3M3 for 6N2P-EV

    verovatno si nesto zeznuo u RIAA kolu da li si radio Robert's optimized RIAA ili Thorsten RIAA?

    izmeri jos jednom svaki otpornik i kond, negde je greska koja je izmerena vrednost izlaznog/krajnjeg otpornika ? obrati paznju na C7 i C6

    ako se na mesto V3 stavi ecc83 treba promenit otpornik od 68k sa 120K

    ovaj kond si kontra okrenuo

    crvenim tackama su obelezena mesta gde treba da izmeris DC napon, tu stavljas crvenu pipalicu od multimetra na bilo koju crnu tacku stavljas crnu pipalicu multimetra evo i pinouta za ecc83

    koliko vidim sa slika, grejanje 6,3V je nepovezano sa plocice napajanja na audio pcb jedino ako ima neka veza sa donje strane plocice a ovo je verovatno shema:
