| Hickok 6000a limitations I just noticed that all the tubes I cannot test are metal tubes. Is there a separate chart or supplement for these types? | |
| Hickok 6000a limitations Maybe it is just the chart but an example would be the 6S tubes . The only one on the chart is 6SN7. This is also true for the 12S tubes. The only one on the chart is 12SN7. |
