XONE:V6 PSU PCB uprated bridge rectifier
ECN No: 985
Assembly No(s): 003-057, iss.2
Date: March 11th 2004
Reason: To ensure reliability when all valve option is fitted to
XONE:V6; especially when used in US with 60Hz mains
frequency.
Details of change:
Assy 003-057, AG4918 issue 2
The bridge rectifier that powers the valve heater cct needs uprating to ensure
reliability when the all valve option is fitted to the V6. The uprated component
is KBL405 (AE5685) and replaces bridge BR2 (AE3477) on PCB AG4918
issue 2. The new bridge is physically larger than the current version, and will
require the leads forming to fit. The PCB will also require drilling as the lead
diameter is greater. A document has been drawn up detailing how to fit this
revised part to the issue 2 PCB: see xonev6_psu_uprating_1.pdf
This change was applied to issue 2 PCBs from March 2004, the issue 3 PCB
includes the uprated component.
