Any real problem to fire it up just to do a short 30 minute practice and then turn it off? I always put in standby for a bit before turning the system off. Jack

No Problem at all for me. Have a Revelation for over ten years without any issues whatsoever. Great piece of gear.

Thanx Mark. I agree with you, it is terrific.

Excellent tube preamp in all aspects. The trick is knowing that the input volume setting also effects the tone. The treble control also moves the mid frequency. It complicates the normal straight forward strategy of zeroing in on your preferred tone setting. Once you're there, it's fantastic.

There is never ever any need to go into stand-by before turning it off. Just flip both switches down when you're done. These little preamp tubes use so little power and generate so little heat compared to a tube "amplifier", it's really hard to hurt them. The stand-by is ONLY there for cold starts, in theory it's a little bit better for tube longevity if you let them get warm for 15-20 seconds before hitting them with the high voltage. Other than that, the stand-by really doesn't serve much purpose there.

This is true, and it's true of virtually ANY tube guitar preamplifier. While fairly subtle, there is a tonal change up in the highest high frequencies that varies according to the position of the Gain pot. It's just the nature of these high-impedance circuits, and you don't see this on transistor preamps. If you turn the Gain down below 11 o'clock one may notice slightly brighter top end. As I recall, the mellowest top end occurs when the gain is at about 2 o'clock on the dial. But other things happen there too with respect to gain and drive and subtle compression. And yes, the midrange dip frequency slides around according to the Treble setting as well as the Color setting. Tube preamps really are creative tools full of musical idiosyncracies - harmonic enhancements, dynamic liveliness. It's why most discerning ears prefer the sound of tubes.
