    Default Energy usage- valve amp!

    Is it a genuine concern? I've just had my estimated energy bill for next 12months...£5100!! I'm an average household, 3 bed semi, 1 bathroom, 3 of us here.
    I'm trying to understand what is making us twice the average household and the only think I can think is I have a valve amp that I run probably an hour a day in the week and maybe 4 hours a day at the weekend. I just can't believe it would have that sort of effect
    It's a primaluna prologue 1. Is there anyone who could work out the cost of fuelling this against a typical solid state amp, say a rega elicit and also a sugden A21a.

    The elicit uses more than the primaluna? What does it equate to in pennies?

    in general a valve amp will use about 150watts, or say 2 old biggish light bulbs. not by itself gonna increase your costs to 5k a year. if your in a poorly insulated biggish detached house thats gonna up your costs a fair bit. oldish boilers/rads will too.

    Which means it’s drawing around 1.25 Amps. Negligible. I wouldn’t worry about it. You’d be better getting a smart meter and agreeing with your provider to pay just for what you use rather than a flat monthly fee.

    Many appliances use far more electricity than one would think.

    I made the jump to LED lights years ago. Admittedly, some of the early bulbs were pretty poor. However, I am now using a 100w equivalent cool white in my office that draws a mere 12w. What is more, it is up to full brightness immediately.

    freezers and fridges are high users especially as they are on 24//7. hoovers as well; some are rated at 2000 watts and cable gets quite warm while using. so hoover once a week instead of every day etc. cooking is another way of saving.
    im going down to one freezer soon. that will help a bit.

    Just for a bit of fun, I recently bought an Aiyima A07 power amp (class D) for less than GBP £100, including 32v/5A power supply (Amazon). To my surprise, it conveyed much of my typical listening fodder (melodic rock) wayyy better than it had any right to.

    Following a YT reviewer's suggestion, I explored further and replaced the Op Amps with a pair of Sparkos SS3602s (>£140, imported from the USA - be aware of currency fluctuations / potential import duty / UK VAT costs to be added). Yes, more than the cost of the A07....!

    With the total cost under £250, the modified A07 is remarkably good value and uses a lot less electricity than my main valve amp (Willsenton R8). Unsurprisingly, the A07 doesn't best the R8 for SQ (IMO) but it's more than good enough to sustain extended listening sessions. For now, the A07 has become the default workhorse for the majority of listening, with the R8 used as a treat.

    Oh, and the footprint of the A07 (sans cables at the rear)? Slightly smaller than the front-on view of a standard plastic cover for a commercially released Blu-ray...
