The Express on lower voltage?

[Mark]

I was wondering if anyone has tried their Express on the 260vac power supply secondaries as opposed to the normal 300vac secondaries?

I guesstimate that would drop 50VDC from your rail voltage, I suspect the timbre of the amp would be affected as it wouldn't be as bright, though it may break up sooner.

The other thought is having a pentode/triode switch on the amp. Surely these two moves would lower the volume but change the timbre of the amp. It may not be a bad thing though.

There must be someone here Who has tried an Express with VVR?

Martin, I built an express with VVR. With a 20% reduction (I’m guessing, will have to measure voltages), the VVR is much better than a attenuator in my opinion. When reducing the express to 50% (approx 5 the dial), the amp looses feel and becomes fizzy). In the file section, I have placed a YouTube clip with a Tele. In that video the VVR was set to 7. That would be the maximum attenuation I would recommend.

Has anyone ever liked triode modes? It always takes the face right off of an amp.

I can see a good outcome with lowering voltages on an Express. Softer but still with face would be great.

I really like the body of cleaned up with humbuckers. That's a great tone!

Thanks. iPhone recording, so higher gain sound suffers (compression)
