Re: 577 D1 IV curve question

Hi DW,

It would help if you said what you thought was odd about the curves so we knew what we were looking for. There is nothing wrong at all as far as I can tell other than the base steps are offset. To confirm this turn the silver 10 turn OFFSET pot. As you turn it the offset will change making the entire set of curves move up and down on the CRT. The odd thing is the offset button does not appear to be in the "activated" position. Try pressing this push button. It may be stuck somehow in the active position. Dennis Tillman W7pF
