Mods for a Blue Tube??

[riantide]

So I'm reading this month's TapeOp and there's an interview with the head of Presonus. In the interview he mentions that he typically tries to make it so that the op-amps in Presonus equipment can be swapped out. That got me to thinking.

I brushed the dust off the Blue Tube I haven't used in god-knows-how-long and popped a NOS tube in there and started poking around. The tube helped a little bit, but I was wondering if anyone knew of any mods that can be done to a Blue Tube to make it a bit more useable.

Thanks!

I don't understand why anyone would want to mod it. I think it makes a perfectly usable doorstop as it is.
