Bengineer 827 Posted October 2, 2020 Share Posted October 2, 2020 For a Auralica Taurus Headphone Amp / Preamp. Volume pot on it seems shot, so would need that replaced with something good, and then just a general clean/service too. Anyone know someone good in the Brisbane region that can do this?

Monkeyboi 711 Posted October 2, 2020 Share Posted October 2, 2020 (edited) Hmmmm.. IIRC this preamp uses a motorised dual ganged 10k "A" taper ALPS Blue potentiometer for the volume control. Does it sound scratchy / crackly when rotated? Is the problem on both channels or just one? ALPS potentiometers are normally very reliable and favoured by audiophiles. but as with almost any electro-mechanical component they can eventually wear out and need replacing. Cheers, Alan R.

Bengineer 827 Posted October 2, 2020 Author Share Posted October 2, 2020 Thanks Alan. It's sound seems fine. Balance issues up to about 5-10% though. Mechanically its shot. Super tough to turn and feels like its grinding. Pretty sure it's knwon for being excellently smooth. Amp also seems to be picking up a lot of noise when a DAC is connected. Even though the same DAC has been super clean on other amps.... Link to post Share on other sites

Balance between channels should be spot on. Nothing that can't be resolved by a competent tech that services high end audio. Cheers, Alan R. Link to post Share on other sites
Bengineer 827 Posted October 2, 2020 Author Share Posted October 2, 2020 Yeah, now, to find a competent tech! Link to post Share on other sites
Bengineer 827 Posted October 2, 2020 Author Share Posted October 2, 2020 Is it legal for me to replace the volume pot myself? I know many do it, but without any sort of qualifications in electronics or electrical, is it strictly legal? Link to post Share on other sites

But unwise, unless you have an understanding of electricity and electronics. Link to post Share on other sites

I tried finding info and what I can away with was basically "no, isn't legal". But I can buy a Bottlehead Crack Amp kit and go for it. Any link to some info on what is and isn't legal? Why can I open up a amp and tinker but not a fridge or washing machine? Or technically can I? (Won't be) Link to post Share on other sites
seaninbrisbane 698 Posted October 2, 2020 Share Posted October 2, 2020 Totally Technical in Bowen Hills are very good. 1 Link to post Share on other sites
Winno 856 Posted October 2, 2020 Share Posted October 2, 2020 AV Digitech in Springwood are very good and reasonably priced. I’ve used them previously. Most recently, they fixed a subwoofer amp of mine which another very competent tech had no success with. They service everything and last time I was there they had everything from Japanese home theatre receivers to Audio Research monoblocks on the bench. 1 Link to post Share on other sites
