Tube match problems
Best tool ever...... http://www.vhtamp.com/products/vht-accessories/tube-tester-2 Worth every penny. You can plug a DVM in to verify the analog meters accuracy. Analog meters can be calibrated, mine were dead on from the factory though. You don't have to use test points or speaker terminals. Makes it much safer to bias. |
