| 01:13 | Macintosh Performa 5400 Capacitor Replacement Guide diffhist +8,031 Josh talk contribs (Verification drive: deleted fabricated C1-C10 logic board table (tidy pairs) and the unsourced PSU table, plus the unsourced +3.3 V rail check. Added Apple part numbers showing the 5400 shares its power supply, analogue/video board and CRT with the 5200/5300, the real high-voltage adjustment (29.5 V DC), the 4.5 V battery pack and below-3.0 V threshold, the Cuda reset, and Apple's analogue-board-vs-power-supply symptom routing. {{Unverified data}} retained - no component-level data exists for...) | ||||
| 01:13 | Macintosh Performa 5200CD Capacitor Replacement Guide diffhist +7,411 Josh talk contribs (Verification drive: deleted both unsourced 'typical/representative' tables, including a 220 uF 200 V part named as primary filter on a machine whose DC bus sits near 340 V on 240 V mains. Corrected the structural error that the analogue board contains the power supply - Apple documents separate assemblies, with part numbers. Removed the claimed +5/+12 V adjustment pots; added Apple's real high-voltage adjustment (29.5 V DC +/-0.1 V at D713/D703 via VR501/VR702). Corrected the battery to the 4...) | ||||

Apple's 303 W figure verified and kept. Added the one sourced community finding (Quadra 950 Delta SMP-291AB input board C905A/C905B 1000 uF 16 V Rubycon VXB), the keyswitch 'not a fault' list, and an explicit statement of what could not be sourced. {{Unverified data}} retained - no component-level data exi...) | ||||
