Installed the switch mod with 470 resistors on the speedball for the E 80cc tube. Sounds very good but I can only just crack the volume control in term of loudness. Seems that there is way too much gain. I'm not sure the best way to proceed with this. Install a Potentiometer, or use a resistor in the volume pot?
Any advice would be appreciated. Can't imagine how much better a Mainline would be then this Crack. It may sound different, but would it be better? Max
From the Crack sticky notes (I used this method for a while. After fitting a stepped attenuator I found there to be better range in the volume and removed the resistors soon after). The resistors are a easy and cheap fix if you are unable to alter the your sources gain.
"3. I can barely turn my Crack up at all before it's far too loud, what do I do?
Remove the white wire from the left RCA jack at the rear of the chassis. Solder in a 270K resistor to the solder cup on that jack, solder the white wire to the other end. Repeat this for the red wire with another 270K resistor. This will give you about a -10dB pad at the input. If you still have the issue, try 470K instead. The wattage of these resistors isn't all that important, anything between 1/16 Watt and 1/2 Watt is reasonable, with metal film and carbon film types being most recommended."
