5.5.8 PWB Interconnections
In the following steps the necessary connections will be made between the right channel, left
channel, and rectifier PWBs.
– Prepare two hookup wires as follows: #18 green, 30 inches, and #18 brown, 30 inches.
This wire can be found in the Filament Wire package in the chassis box. Tightly twist the
two wires together along their length.
– Route the green/brown twisted pair to the rectifier PWB through the cable clamps at the
rear or the chassis.
– Install a quick-disconnect connector on the green #18 wires and attach to the 6VH1 post
on the right channel PWB.
– Install a quick disconnect connector on the brown #18 wire and attach to the 6VH2 post
on the right channel PWB.
– Cut a 26-inch long #22 slate wire and a 4-inch long slate wire. Combine the wires and
attach a spade terminal. Connect to the #3 terminal on the right channel PWB barrier strip
(TB3). Bend the barrel up to near vertical and orient the spade terminal to face the front of
the chassis.
– Feed the free end of the long white wire to the left channel PWB through the cable clamps
at the rear of the chassis. Attach a quick-disconnect terminal to the short white wire. It will
be connected later.
Note that in the following step, hookup wire rated for operation at 600 V (or greater) is used
due to the B+ voltages used in the amplifier.
– Cut a 26-inch long #22 red 600 V wire. Attach a spade terminal to one end of the wire.
Connect to the #1 terminal on the right channel PWB barrier strip (TB3). Bend the barrel
up to near vertical and orient the spade terminal to face the front of the chassis.
– Feed the free end of the red wire to the rectifier PWB through the cable clamps at the rear
of the chassis.
