I just finished my 3rd recap of Pioneer SX-1250. I recap 2 or 3 receivers per month, so I do a lot. After the recap and replacement of all 2SA725. 726, 750, and 2SC 1312 and 1313 transistors I naturally set the DC and Bias currents. What is surprising is that on both of the last 2 1250's, and an SX-850 I recently did, is that the DC is off, OK, but the Bias has been absolute ZERO! It is supposed to be 100mv! At zero, there should not be enough voltage to turn on the transistors! Was this setting not done at the factory on every unit? Or was it supposed to be set by the retailer before delivering the unit? I never worked in a Hi-Fi store in those days, I sold cameras. Is this something others have found?
