[NJARC] September Events

[Nick Senker]

Hi Scott, we tend to recap these sets but not pay too much attention to the resistors which can increase in value , especially when hot.  I remember reading the grid leak resistors on the output tubes can cause the symptoms you describe.  Try replacing the 330K and 490K resistors on the grids of the 42 output tubes.  Nick Senker
