Just to keep you happy, I've upgraded two of the channels with TL071's (I happened to have two available). On brief listening tests they don't sound any different?, and I was particularly surprised that they don't sound noticeably quieter?, 741's are supposed to be pretty noisey opamps, and the 071 is a low-noise amp - but the difference seems very marginal (and I might only be imagining it!).
I'll see how it sounds at the gig next Friday :lol:
Incidently, each preamp is on it's own little PCB, and they link across, power and ground - with the output signals going via unscreened wire to the virtual earth mixer (another 741), which has a Presence control and a Master Volume. The preamp boards are silkscreen printed, and have the name 'Pink House' on them?, has anyone heard of that name?. The amp it self has no name at all, it just says 'PA 120' on the front.
