		                      Low Intensity
	
Low intensity can be caused by arcing between the body of R16, 470 kilohm
resistor [PN 6-474-1], and front panel chassis.  On each unit received
for service, position the body of R16 at least 1/16" away from the
chassis and controls.

		      CRT Mounting Spacers Change

To complete a production run of HO-5404 kits, the two 6-32 x 1-3/4" round
spacers [PN 255-708] used to mount the CRT were replaced with four 6-32 x
7/8" hex spacers [PN 255-724] and two 6-32 x 3/4" setscrews [PN
250-1158].  Two of the hex spacers are joined together with the setscrew
to make the 1-3/4" spacer needed.  Manual insert [PN 591-5100] tells the
customer how to install these spacers.

	Q101, Q102, Q115 and Q116 Basing Screened Wrong On
                                               [PN 85-2978-2] Main Board

On the [PN 85-2978-2] main board, the screed showing the drain and source
positions at Q101, Q102, Q115 and Q116 are interchanged.  The correct
basing is shown in the drawing:   

[[Picture a semi-circle, with the top of the semi-circle 'D', the bottom
'G' and mid-way in the arc, 'S'  ]].

The [PN 85-2978-3] main boards are screened correctly atthese FET
locations.
