My TV can't change the volume if you select optical output, other than getting an AVR what other options are there that would allow me to control the volume via a remote? I have the TV connected via optical to a DAC and the outputs of that to a power amp.

I have a notched rotary encoder on a piece of equipment that's used to change program types so it's controlling digital parameters and it's not changing correctly. The encoder is sealed, it's one of these new kind of plastic body pot. Is there any method to opening them to try cleaning them?

Does anyone have experience with a flickering display on a Cambridge Audio Topaz Amp? The display gets all garbled and jumps around or will sometimes go completely dead, if you give it a firm tap with your finger it will come right for a bit and then start up again a while later. Another...

I have a small 8" sub which only has low level inputs, it doesn't have any unusual hum with nothing connected but as soon as you connect it to an amp's pre-out it gets a rather loud and noticeable hum. I've tried 3 different amps and all have the same outcome but if I connect a cellphone...

I really like the LOUDNESS effect that was especially popular on many old school Japanese amplifiers, does anyone know how I could mimic that effect with a parametric EQ? I've had a good look around on Google but can't find anything conclusive as to what bands I need to tweak in order to get...

I have an old Wella Pyropen, butane gas powered portable mini soldering iron, very handy tool when you need to do a quick solder job. But the damn thing randomly stops working, it'll be fine for weeks/months and then one day I'll try using it and the gas will not want to flow or if it is its...

I'm trying to help some friends locate their electricity meter, there's a new meter reader and he can't find the meter. They rent and the owners of the property have never lived there and have no clue where the meter is. Problem is they normally pay around R1500/pm for electricity but their...

Where are the good 2hnd/pawn shops in Capetown? I'm visiting this fine city and I wouldn't mind looking around to see what is on offer, I'm probably going to be all over so they don't only have to be in city bowl. One thing I'm always looking out for is old camera lenses.

Why do wall wart type power supplies often output voltage well above the rated output voltage, the spec on the side will say 9v dc and checking the actual output it will read 13.5v? Does that mean it's toast? I have a box of various power supplies, it's often its handy to have spare power...

I'm looking for an artisan sized 36mm wide paint brush with very fine bristles, for painting furniture etc? I've noticed when using high quality artists brushes with automotive prints that if you are careful the bristles are so fine they don't leave lines in the paint. I've read before that a...

The turntable guys seem to have mastered polishing turntable lids, what's the secret? I can get plastic glossy but it will still have a lot of residual scratches, it's as if plastic is so soft the polishing process itself introduces scratches no matter how careful or fine you go. I'm basing...

After my previous experiences with Ryobi build quality I swore to never again buy their rubbish tools but a member of the public was kind enough to steal my Makita cordless drill a few months back and I can get one of these Ryobi 18V LI-ION CLD-180 Cordless drills virtually brand new for R500...

If you need a phone contract or Mobile data this is an insane deal Phone 0831233667(you may have to hold for up to 30mins) or go into a branch but that's a pita as you need to take bank statements etc - Contract application must be submitted before end of business today, even if its not...

Does anyone have any idea how much a replacement Alpine Car Radio metal fitment cage and plastic face trim might cost? Its for a reasonably recent single DIN model, how universal are they, would a specific part number need to be ordered or will most single DIN units use the same cage and trim?

I've done it many times, as I'm sure many others have, connecting a cellphone(or similar portable device) headphone output to the line level input of an preamp/amplifier. From what I understand there will be impedance and voltage miss match but what are the implications of doing this from a...

I found this rather handy thing on a US website, its basically an extension lead that you plug a power tool into, switch the tool permanently on(ie locked ON either with the switch mechanism itself or a cable tie if its a momentary switch only) and then you can remotely power it on/off via a...

I've had my share of foam speaker surrounds rotting, finally disintegrating and then needing replacing. Is there anyway to look after them when new to prevent this, perhaps treating them with silicone-free plastic dressing or silicone itself etc?

Does anyone have tips and tricks on how to weld velcro, I'm thinking perhaps with a hot soldering iron or heat a welding rod with a blowtorch and make little melt welds as needed. The commercial way is apparently ultrasonic welding. I want to put little velcro straps on my cables(spare...
