Hey everyone, I don't post here that often, I'm mostly a lurker, but I wanted to ask how you'd approach this. I used to own two Clark 5F1 amps, two others that were DIY projects, and my son as well as two friends have 1x12 Champs. All of them (except for one 1x8) had standard 5E3 sized cabs with Champ chassis cutouts. One thing they all had in common is that, because of the positioning of the 6V6 on the chassis, a larger speaker such as a Celestion Blue or a Tone Tubby could never fit. The 6V6 and speaker magnet get in the way of one another. I'm in the process of building myself another 5F1 now, with the intent to use either a Tone Tubby Alnico Red, a Celestion Blue or a Jupiter 12LA. These speakers sound mindblowingly good with a 5F1, yet it's a sound I've never been able to achieve because of cabinet sizing and speaker positioning. For anyone that's done this, or has such an amp, how did you deal with the cabinet sizing and speaker positioning? Thanks.
