effects of different HT voltage

razorrick1293 · 10th April 2011, 12:29 AM

Hello, i made a post a while ago about high gain preamps, i've built that now and i ended up basing it on a mesa boogie/soldano SLO. but looking at the schematics both are practically the same circuit, except the SLO uses about 60v less on the preamp. so other that reduced head room, what other differences in sound could i expect from lowering the voltage? how much will it change the distortion?

Look up your tube data sheets, you can eyeball what voltage changes will do looking at graph.
