I just checked all the resistors again. Everything at the right spot. But I see other voltage issues.   So I am not getting 6.2 V at the pins. Instead the readings are 4.5V. Pin 4,5 and transistor all have 4.5V I back tracked the readings to the input to the diode rectifier circuit and the...

Thanks for all the help!   I have not measured the DCR. I am not an expert, so I don't even know how to go about it. What will it achieve? Do you want me to check whether the resistance is symmetric on both channels?   I haven't tried a completely different tube. I just ordered a matched...

Hi there, Just finished building the Cornet2. Thanks Jim for the awesome piece of electronics. Everything works okay, but not perfect. Unfortunately, the right channel is low, not by much, but noticeably lower to shift the balance to left side. I swapped the 12AX7's and it doesn't solve the...
