Thanks a lot analogsurviver, very insightful.
I have one more question, what about power conditioners? Will they help in conditioning the power fed into my vinyl setup? I'm asking because a friend of mine suggested that.
Also, are power conditioners the same as automatic voltage regulators (AVR)?
I'm worried the power extensions might have some minor shortages. I guess I should've mentioned this earlier.
When I was hooking up my plug extension, it was onto another extension. And I have another box-shaped socket splitter that splits one socket into three, and it has a little LED indicator light. When I had plugged it in without flipping the switch on, the LED lit up. Even before turning on the extension was already powered albeit maybe at small voltages.
I have no other power outlets here to test out whether my extension is faulty, or the extension I am plugging it into was faulty, or the wall socket itself.
On another note about cleaning records, a record seller told me to wash it under running water with a soft cloth, and do not use any chemicals on it. Now I have a few conflicting opinions. Wouldn't washing it under running water will soak the label? I'm worried the label might get washed off.
About power conditioning. Yes, but ONLY if entirely inescapable. That ONLY applies only in case that the power consumption of the device is too high for the use of batteries of one sort or another. You can go bankrupt with power conditioning and still not even meet let alone exceed the performance of batteries. Please send the link for the exact Project phono box you have - perhaps it can be reasonably powered off sealed lead acid battery instead from wall PS it is probably used originally - NO hum originating from preamp guaranteed. A $ 30-50 battery/charger setup can easily outperform power conditioning for incomparably more $$$.
Your TT is a direct drive model. Save for the very TOTL direct drives such as Technics SP 10 MKII and MKIII, which have power supplies in a separate box that is connected to the turntable with an umbilical chord, all more down to earth direct drives, yours included, have internal power supply. It contains power transformer - and this one WILL vibrate at the power frequency of the line feeding it - causing both mechanical as well as electrical hum. Even if the transformer itself is so quiet that you can not hear it - believe me, phono cartridge IS more than sensitive enough to reveal it. It is the greatest defect/ommision in most of direct drive designs, giving them far worse SQ than of which they are in fact really capable of. It is impossible to go back to internal transformer once you heard the veil lifted from the sound by eliminating the power transformer within the deck.
Once you sort out your phono hum problems etc, I might write a tutorial how you can modify the DD table to get that pesky power transformer out of the picture. A certain level of electrical knowledge and ability to solder required - SAFETY FIRST rule applies, as line voltage(s) is in question. There will be no photos regarding this - turntables vary wildly, so only general pointers with recommendations how it could be done will be published. A Service Manual for the table in question will be mandatory.
Phono CAN be made ( reasonably>very>totally inaudible ) hum free.
FORGET tap/running water. Distilled water in your local discount store is incomparably better solution to the problem - just buy the quantity with the lowest price per volume unit. You can add isopropyl alcohol to it > THERE ARE GODZILLIONS OF RECIPES ON THE WEB - it boils down to percentage of alcohol in distilled /deminaralized/reverse osmosis produced water plus some surface tension breaking agent, such as usually contained in dish hand washing liquids - a drop per litre of alco/water is all that is needed. And I do not think we will be exchanging Malaysian Dish Cleaner for Slovenian Dish Cleaner transporting them around the globe - only to find they are exactly the same ABC product by the same XYZ company ...
Some record labels are water/liquid proof - some are not. Treat them all as if they were not.
