Ok, so I picked up a Weber 6a40 (BFSR clone) for the cost of the kit from an acquaintance who needed the money. Its point to point wired by a good amp tech/builder here in town. It is a stock kit save a trem boost mod and loaded with AlNiCo speakers. It sounds ok, the individual notes are nice, but chords get muddy fast. I assume that the tubes will have to be replaced as they are whatever came with the amp. I'm pretty well set with the replacement tubes already. What else should I anticipate changing out to get the amp sounding more like a BFSR? Which resistors, caps, etc should be replaced? What about the pots, jacks, and things like the reverb cable? I've built plenty of Hifi equipment and messed around with my Class A little amps. However, this is my first foray into a "big boy" amp and I think the challenge will be a good one. I play mostly blues and classic rock (muddy waters, early clapton, allmans, derek trucks) with a tele, H535 and SG. Thanks for any input. Hope everyone had a good week!
