generg Napisano Decembar 15, 2010 Share #889 Napisano Decembar 15, 2010 what I can say very clearly the sound changes clearly when you change the type of C3/C4. I tried it with Elna Simic II and with Panasonic FC.most of you know the differences, Elna is "Wodka" and "Blues" and "I am getting older" an Panasonic is champagne and "more drive" and "I feel Young".you can choose fitting to daytime, Elna in the evening and Panasonic in the morning don´t do it vice versa.....

Zen Mod Napisano Decembar 15, 2010 Autor Share #892 Napisano Decembar 15, 2010 schematic is drawn in Eagle , as necessary step for pcb constructionthat's iterative process (back and forth) so - few things ( not necessary in "just" schematic file ) are there - as several PSU taps , same as few wire bridges ( dracht brucke)that X is from these reasons therejust ignore thator solder banana plug there , just for fun:rofl: Link to comment Podeli na ovim sajtovima More sharing options...

Tea-Bag Napisano Decembar 15, 2010 Share #895 Napisano Decembar 15, 2010 So update. No listening yet. My large offset got cured by a huge resistor change from default of 390 to 2k with 500R pot.What bothered me more, was now the bias was up to 720mv. I swapped the resistors out of the other channel, and offset from +1v was easily dialed in with R12. Bias at .560mvSo I am thinking that at the bias change has somehow made the Fets less matched, as they do with different levels of current.I am going to swap out with my last matched pair on this channel, go back to basics for R26 and see how this goes.

Tea-Bag Napisano Decembar 15, 2010 Share #899 Napisano Decembar 15, 2010 Tea - what voltage you have across R23 ? (just in case - what's value of R23 on your pcbs ? somehow I lost the track with you all )I have not checked it since swapping Power resistors to sp300b's values.The resistor should be 47R. I will check the value later, before swapping out R100's. Link to comment Podeli na ovim sajtovima More sharing options...
Tea-Bag Napisano Decembar 15, 2010 Share #900 Napisano Decembar 15, 2010 Does it looks better, now, at least ? Look better, no - my amp's are all ugly. I tried to boot up laptop for some test music last night, blue screened and core'd. Several times, so I just went and played X-Box with my son.
