I have a mm HD130 212 with the transistor bias and when I measured across 3.9 Ohms resistor I only got about 10mV as the highest value even though I put the bias pot in the highest position(giving highest bias). The amp works but I'm a litte bit worried about the bias configuration. Do anyone know if its a problem? | ||

Could be bad tubes or bad 2N6488. | ||

So the 2N6488 are the same as JE1692 in the schematics? And how can i check if its bad or broken? |
