Re: 7704A - Delayed Sweep Intensity Too Bright

Mark Vincent


See if having the A/B intensity turned up and the crt bias up (more negative at the grid) helps. If your S/N is <210000, check Q320, Q322, Q420 and Q422. These are in the two heatsinks on the right side top. If these are leaky, use KSP10BU. I do not see any internal intensity control in this model. It may be that the delayed signal is to be brighter to give contrast.
