Please help a newbie with PSU current requirement for Aikido linestage
I'm building an Aikido linestage using all 6SN7 tubes. B+ is 300V and each (half) tube draw about 10ma. I use a PSU that can provide maximum 50ma for both channel.
I'm a newbie in Tube amp and Electronic in general, I have a question: Is my linestage draw 40ma in total or 80ma? If 80ma then I must consider building another PSU, one for each channel
Thanks in advance
If you are using 350R cathode resistors for both the input and output stages, you are drawing 10mA per tube @ 300V B+.
Thus, you have a current draw of 40mA from the PSU. Your PSU should work fine with this circuit.
Are you using a preconfigured PSU for your Aikido? If so, from where? I'd be interested in possibly picking one up as a test against my homebrew PSU....
