Need a schematic for a Jackson model 580 tube tester. Any help? Thanks.<P>------------------<BR>Jim

That's an oldie, and one Jackson I do not have. However, save one plain 648 I have, every other Jackson has a schematic stapled to the bottom of the box. Now, Jackson also made their testers in a counter-top model, in a steel case and no lid. The schematic is then sometimes taped to the bottom of the case. But, as I say, I have only owned one Jackson that did NOT have a schmatic inside. <BR>If you aren't so 'lucky', someone here ought to have it. <P>------------------<BR>

Guess I'm unlucky, no schematic inside. There are 2 resistors which I can't make out their value. Have to keep looking.<P>------------------<BR>Jim
