I'm looking for some help finding someone to repair my Technics SP10 turntable.
We seem to have limited options in Perth. I have tried a few people, i seem to either get - Yes thats an open cheque book please - Yes i can do it, then excuses, price hikes and no action, Or yes I can but i don't want to (my interpretation, no thats too hard for me but I don't want to say that).
Either way I have had no luck.
I would post over east if I thought I could get it repaired.
Any ideas would be greatly appreciated.
I've had a Sansui 1000X receiver for a year or so and it has a long standing "white noise/hiss" problem in one channel, this occurs all the time even when the volume is turned right down.
I recently linked the Sansui 1000X pre-amp out into the main in of another amp and it sounded great - no hiss whatsoever.
I am now thinking of repairing the amp, I assume a re-cap of the main amp board(s) rather than pre amp is in order but I was just wondering if there could be another cause. I don't know much but read somewhere that the output transistors could also be a problem.
Would anyone out there have an informed opinion on this.
For some inexplicable reason I have been running a 1970's vintage stereo setup for a few years now (Thorens TD160, Marantz 1030 and Whafedale 306) - probably to do with nostalgia and being a cheap skate rather than hi-fi-delity, but it sounds fine to me. The amps have started breeding and I now have about 5? One is a Sansui AU101, which has now developed a loud humming/buzz and "bitten the dust" and was on its way to japanese amp heaven. But having read the pete_mac post ( http://www.stereo.net.au/forums/index.php?/topic/51043-sansui-au-101-resto-and-upgrade-for-snaer/ ) I decided to try to the recap thing! Nothing to loose.
Could I ask a few questions before I start buying/soldering and perplexing, please refer to the picture I have attached which shows the gubbings of the amp.
I have labeled four sections in the pic..... A, B, C and D.
Referring to A and B. There are 4 resistor thingy(ies) missing but the amp was working OK, should I add these back? Very strange.
Referring to C. There is leakage at the bottom of the big blue capacitor - is this an indication of a good cap gone bad? Also may indicate pale blue are original caps?
Referring to D. There are a mix of pale blue and grey capacitors, are these all original or has a partial recap be performed already?
Anyways, I thought the best course of action is a total recap of all based of the approach of pete_mac (and others).
Can anybody suggest a "set of capacitors" or an (australian) supplier (jaycar?), I have a low res copy of the owners manual (from the WWW) which lists the originals but I'm not sure where to start. (I can post this if needed).
Sorry if this is in the wrong forum but this is my obligatory introductory post. When I have a bit of time I will troll through the forums to get a feel of the discussions. If anyone is interested I'm happy to put together another post into another forum on recapping the amp when I've finished (from a beginners perspective!)
