I finally located my tool case, has a bunch of sprockets and tools, including a large variety of drivers, but no allen wrench small enough for the 2mm screws. There's a local hardware store... I probably would not be able to find a set for $2, but it might be cheaper after the $9 total price from harborfreight if you consider shipping. And maybe, I could just take the amp with me and I could borrow one for 5 minutes, they let people borrow tools at the auto parts stores.
Can't help but notice the irony... the set you found, called the Pittsburgh... I live in the city of Pittsburgh. LOL.
Ludoo, It's up to you, but I am already very impressed with the amp built to it's current spec. What do you expect the larger caps to do, increase bass extension? The bass extension already matches (mostly) my FiiO solid state amp (without boost), with my Amperex 6DJ8 "Bugle Boy" and Vokshod 6N23P tubes I don't feel like anything is being "held back" on this amp. Maybe you know something I don't, but the sound is already "enthusiast grade."Edited by Evshrug - 3/28/13 at 7:37pm
