Hi, in your FCUPS literature, you are using a paralleled triode section 6SL7 capacitor coupled to a 300b. There is a CCS on the anode, with about 365 VDC into the CCS.
What is the operating point you were using in this amp for the 6sl7? Do you adjust the CCS until the anode output is where you want it, or is it best to set via the current sensing resistor to about 4.4 mA?
Thanks,
Matt

Hi,
I would set this for around 160V - 250V on the anode (maybe start at 180V).
The different operating levels will sounds a little different, so you can see which sound you like best.
