A 1KVA servo stabilizer will be better than the stabs from v-guard.
I prefer and suggest CVT (Constant Volt Transformer) over Servo for HT purpose. There is enough discussion in this forum on this topic you can search and get to know.
I have calculated that the to power consumption would be approx 450 wtts. Will V guard Crystal plus will be suitable?
Thanks for the advice
For your load 1KVA is more than enough. I can give you a suggestion for the best available CVT / Stab., just look out for conventional A/C stabiliser which we used to keep on a wooden stool / on wooden wall bracket. They are normally 4 KVA but never mind its like an asset.
The easy way to get this is keep your A/C mechanic informed so that he will give it to you whenever/ where ever takes it on exchange. Otherwise they are simply putting in scrap for RS. 80/kg. You can get it from the scrap dealer too for 100/kg. So over all it should not be costing you not more than RS.1500/- for 4 KVA. That too if you can get old SYSCOM or ALACRITY or BLUEBIRD you are lucky. Those day only copper winding was there which is more stable now getting copper is difficult including V-guard.
This way I have purchased more than half a dozen and given it in my circle.
The one what you are seeing here in photo costed me just 1.5K of course the digital metre is my handy work. This is serving my stereo setup, earlier it was in my HT now that I bought a Bhurji CVT for HT this has come to Stereo.
So people think before you spend.
