b. Transformer removal: The transformer is held in place by four l/4" bolts into
separate nuts on the right side and a retaining nut plate on the left side. To remove the
two right-side bolts,
it is necessary to remove the heatsink assembly to gain access to
the two nuts. Remove the
8 heatsink mounting screws, 7 front panel screws and 7
input/output plate screws: now you may slide the heatsinkassembly to the rearand lift
it up, out and to the left to gain access to the transformer nuts. The two left-side
transformer bolts can simply be loosened until the nut plate falls off. Pull all
transformer spade plugs from the power
PCB and lift the transformer out of the chassis
(brace yourself). To replace the transformer, reverse the above procedure; it is
necessary to hold the nut plate in place with your fingers to install the two left-side
transformer bolts. Reconnect all transformer spade plugs as shown on the power
board assembly diagram.
