I know that this is probally a rehash to some but I thought I was clear on all the discussion topics and procedures before I tackled this , I guess I missed something .
All tubes had a great deal of screen burn and I wanted to dress up the games with newer looking monitors . They also all worked completely . I swapped out 6 tubes over the weekend with the results varying from fantastic to downright bewildering .
On all the tube swaps I used the original yoke that was mated to the chassis ,but I switched the convergence rings - which I think is correct . So here goes :
swap 1 : go7 swapped out tube for tube 9 pin - 19vlmp22 went great looks same.
Swap 2 : go7 swapped out with a48 xxx 9pin not so great pic comes up right away but only fills center of screen about 3" high by 7" wide .
swap 3 : 4600 swapped out with a48xxx 9pin same results as posted above .
swap 4 : 4600 swapped out with 51xxxx 9 pin piece of cake looks great
swap 5 : 4600 swaped out with another 51xxx 9 pin results were less than desired - same smaller screen display as with swap 2 and 3 .
swap 6 : 4600 swapped out with 19 vxxxx 9 pin . picture comes right up but have no control over brightness . Barely make out pic between the retrace lines .
All have some issues yet with convergence and colors as one may expect that need to be addressed .
I thought that the key was to match up the pins and this would make for a good swap .All grounds have been reconnected or spliced in properly . None of the chassis have been capped yet as they were all working before my swaps . Enclosed some pics . Any help with this to clarify my error is appreciated .
