If you are concerned about the solidity of the bass through that section of the bias circuitry, you could also add another 50-100uF of filter capacitance at the wiper of each of the four pots. I don't think you'll benefit much, but you can do it. Modifying equipment is kind of a black hole. The goal, ostensibly, is to produce a better piece of equipment. However, when confronted with the question wondering which is the best plan, prepare to be confounded with a thousand answers, all of them reasonable and compelling in their own way. For instance, you could use electrolytics to bypass the wipers of your amp. Others might say that that plan if foolish, what you really need is just a small, less than 1 uf of capacitance, filter to stabilize the DC and provide a grounding path for the AC through the grid resistor, and others will demand that if you aren't using paper in oil caps you are tempting providence. I don't know. I'm pretty sure they're all good plans including just kicking back, listening and thinking about it for a while. I could be wrong.
