At last, I can finally get this started. The AU-919 is basically done, just waiting for some extra potentiometers to come in. Some overall pics and one board for now, I will be starting with the tuner/preamp section. The initial thread where I got it can be found here: http://audiokarma.org/forums/index.php?threads/finally-got-the-last-receiver-ill-ever-need.832556/ TONE AMP BOARD and TONE CONTROL BOARD (F-2890 and F-2889) Before C01 and 03 along with C02 and C04 form a 5uF "bi-polar cap" and is bypassed with a .047uF mylar film cap (C05 and C06). These were replaced with a single 4.7uF Panasonic ECW polypropylene with a jumper placed to allow for maximum lead spacing to accommodate the big poly cap. C05 and C06 were removed. C13 and C14 are 47uF 25v bi-polar caps and were replaced with 47uF 35v ES bi-polar caps. C15 and C16 are 22uF 25v bi-polar and were replaced with 22uF 35v ES bi-polar caps. The 0.1uF bypass caps for C13 and C14 (C09 and C10) were replaced with a 0.1uF Wima MKP10. The 2SA872 input pairs (TR01-04) were replaced with matched KSA992. The small mylar films for the tone EQ were all replaced with Wima MKP and FKP.
