Hi Myles,
I gig with a mesa Blue angel head into a mesa duo bin with celestion v30s and a closed back.
I've been unhappy with my sound over the last few gigs, and I'm wondering if the (original mesa)tubes are getting a little long in the tooth. I'm wondering what to replace them with. The angel runs 38 watts class a, with two 6v6s, four el84s and 5 12ax7s, plus a rectifier tube (can't remember what kind).
If at all possible, I'd like to maximise clean headroom available, as sometimes my setup can't quite stay clean enough in certain rooms. Is this possible through tube choice, and are there tonal tradeoffs?
If it's unlikely that I can't get any more clean headroom, what possible avenues for modification can I pursue? an extra power stage that I can switch in and out if needed would be great, but am I right in assuming that would need an extra transformer?
thanks in advance,
Martin
