Hi, I remember the old RS Electronics shop that was near Wits Tek in Braamfontein in 1990. I remember a small sound room with Daan Jacobs Reference 2 and 4 speakers. I think he had a goatee and was well respected by the students studying electronics. T1 - T3. I studied electronics at Wits Tek...

I recently phoned RSE from Australia and spoke to an Afrikaans chap about the mosfet amps, preamp and reference 4 speakers. They told me to email them and I have never had a reply. Not on Facebook messenger or several emails for quotes. I have come to the conclusion this DIY system in no longer...

Does anyone know of a good quality low noise DAC sold from Banggood or AliExpress? I am aware the Sony D100 and Sound Devices have very low noise and brilliant audio recording. Sometimes you get lucky and find something online that has amazing recording specs however affordable. I did a search...

I have owned a Sony MZ-RH1 for a few years and the left OLED has faded to nothing today. I see Sony no longer make parts and trying to find a spare online is impossible. I bought this MD recorder to transfer my disks to my laptop using Sonic. The unit records really well and may be end of life...

I remember the SACD replaced CD for serious audio lovers and see DSD is a newer standard. You can buy standalone players for these however I am sure people are using streaming services like IDAGIO for classical music and a quality DAC. I am curious which ones would work well with an iPhone or...

Hi, the speaker fabric on my Reference 4 speakers have faded over 30 years. I live in OZ now and went into Jaycar and Spotlight to look for more. They have the wrong type. A tight stretching weave for clothing is what they have. The fabric I have is not as stretchy yet you can see through the...

Hi, My RS preamp has an issue with the volume control. It is not balanced anymore. It is a dual log red dot 100k. Does anymore know where you can get a new one or an equivalent. Thank you

Hi, I am looking for info on the old RS electronics Annilator? When looking at the Hafler is looks almost the same except the relay. The mosfets are Hitachi in T03 form factor. RS Electronics still sells this amp and their website clearly says it is their intellectual property. (That is fine.)...

Hi, can anyone how I could test my old 6600uf 75 VDC amp caps? They are 30 years old and bought from RS electronics. I see they were made by Sprague Powerlytic who was bought by Vishay in 1993. They do not make a replacement cap like this. I am having trouble finding a replacement for my amps...

Hi, I built the 250w V8 Annihilator amps in 1990, so over 30 years old. They have 4 x 6600uf 75 VDC caps in each amp. I noticed the Bass was not as good as it used to be however not bad. The attack was lacking. More washed out and muddy. Questions: 1. Can I test them whilst still connected...

Hi, does anyone know which ribbon tweeters these are? Thank you

Hi, I have 2 x RS 2 preamplifiers which I built in 1990 along with the V8 250w mosfet amps and reference 4 speakers. They all still work really well. I see the RS 2 preamp is almost an identical Hafner DH 101. I have the original RS documentation from Mr Jacobs with the component list, PCB...
