generg Napisano Septembar 30, 2010 Share #377 Napisano Septembar 30, 2010 Oops. I ordered http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=516-1310-ND for my LED's. Think they are 2mv typical. This might explain why they are flickering a bit with a signal pumping into it? Congrats Generg, I am a further bit behind. Have a nasty cold. I have one channel with minimal offset, .750v across source resistors, the other is offset of 10v, and it biases to 1.8v quickly. Something wrong with it, it didn't respond to R12 or R25 fiddling at all. Maybe swapping out LEDs will get me further down the road.. I do need to take some serious measurements of both channels and present them here. Generg, Once you go full range driver, I think you'll be happy. What implementation for Sonidos you going to use, BLH, OB? Tea-Bag hi tea-bag, we are always close together in the race to hear a new amplifier....... when I put my chaotic point to point construction together I was very slowly because I new to look again at he circuit and compare scheme and construction is very dull and difficult. I could imagine you forgot one of the long connections from the different isles in the beginning to the output, for instance Q2 to R32, or the one I forgot fromCNY17 point 4 to drain of Q14. I found it before I switched on. But point to point is also a pleasure, more concentration, more awareness how the scheme works. Good luck!

Can't be working right.......in fact - use whatever you want , red/green/yellowthey need to be either round 3mm , or square ( even if I didn't check that ) for physical placement on actual pcb , and 20mA type - because of 5mA current through themdifference in workng voltage between green/yellow/red is of no consequence here - they're just for establishing voltage for cascode Link to comment Podeli na ovim sajtovima More sharing options...
