[1]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.
[2]I would put a 33K across the outer pair of lugs on each level, and a 75K in series between each center post on the RCA jacks and the wire connected to them. This will give you some serious padding, as well as maintaining a reasonable input impedance.
[3]Try 50K in place of the 75K.

I found a few spare hours to pad my volume and tackle a channel imbalance found at low volume levels. Hoping to address both issues with one of the solutions proposed above by PB.
Currently, I find the maximum comfortable volume to be at 1/4 turn. Hopefully this will give an idea of how much padding is necessary to allow for finer volume control.
Which, of the 3 above, would be my best option? Or perhaps there is another solution?
Should I be looking for metal/carbon film, 025W resistors for all? (Would something like these work: http://www.thesource.ca/estore/product.aspx?language=en-CA&catalog=Online&category=Resistors&product=2719018)
Apologies if this is an ignorant question, the Crack + Speedball was my first DIY electronic project!
Thanks in advance!
