I don't notice that. I can go as low as 37V. You have to decrease Iamax to makethe graph readable.ruffrecords said:I tried it with the ECC83 to try to get the operating point I use in the EZTube mixer. It won't let be set the HT voltage lower than about 267 volts. Am I doing something wrong?

I can go down to 37V and 44V respectively.My3gger said:I've got the same problem with ECC88 and ECC99, didn't really try others.
Not really, since it takes only triode mode into account.HT voltage is unusually high for typical mic amps, something seems strange here or it was meant mostly for power tubes.
