Hi all. I have a 1961 Brown Pro with a replacement Output Transformer from a mid-60s Twin Reverb. It's clean and punchy, which is great. The downside is that I never get any real compression and sing, even when I get tube crunch (at around 7). Malcolm Young or Pete Townsend would love it, but I only get to play at considerably lower volumes. To be honest, this is a clean amp for me anyway. But I'm curious: What tonal difference do you all think a proper Brown Pro OT would make? Would I get more smoothness and balance, or just less bass? I'd appreciate any thoughts. TIA.
