Some nice work I only wish I could drop on a pair cheap enough to refurb ;)

Some nice work I only wish I could drop on a pair cheap enough to refurb ;)
What about this one? Quite tempted myself, Martin

I was actually given a Sansui Tuner by a chap. I really didn't know what it was. But the second I hooked it up to my system I just knew it was something great. It is an old wood cased tuner and I have spent some time on the cosmetics and it looks good as new and sounds great.
Nice job Pete and great photos. I just love the look of Sansui kit from that classic era, amazing build quality:thumbsup:
Ah, I see. My father is a tech/hobbyist (with an enormous Sansui collection... we hav around 55 units between us!) and he has all of the usual diagnostic instrumentation including a 'scope.
How would I go about measuring such 'ringing'... across the terminals of the filter caps or elsewhere in the circuit?
I've also been advised that I should try a resistor in series with the by-pass cap (in the order of 1-5 ohms). It seems counter-intuative to me, but I guess it couldn't hurt to try it. I need to read up on this a bit more methinks.
One further tweak...
The original power cable was quite... erm... 'poxy'. Thin figure 8 twin-core as fitted as standard to US models. I decided to upgrade it using some Belden 19364 power cable with 3 x 14AWG conductors, 'belfoil' shielding and integral drain wire, and a nice (not too over-the-top) Martin Kaiser silver-plated AUS mains plug. Given the size of the cable (around 10.5mm diameter) the usual strain relief/cord grip wouldn't work, so Dad sourced me some nice Thomas and Betts heavy duty jobbies which worked perfectly. They are pretty big but you don't see the rear of the amp anyway.
Very happy with the end result, and the thin original cord is banished forever!
A HUGE thanks to David from mains-cables-r-us for his quality customer service. Highly recommended (as most of you on here already know ;) )

I also made up some cables for my DAC and DI using Martin Kaiser IECs and AUS mains plugs, some heatshrink and some carbon-look Techflex.

That should've given a massive sonic improvement, Pete, as that old power lead was pretty shit!
It's areas like that in audio where significant advances have been made since the Sansui was produced :)
Marco.
Indeed Marco, first impressions are very promising. Of course, it's damn near impossible to do a A/B comparison once this kind of tweak has been undertaken, but even at low levels there is the impression that the music sounds a bit clearer and unstressed. Whatever it is, I like it!
Now to get my brother-in-law to visit (he's an electrician) and install that dedicated power line that I've been hankering for!
Nice one, Pete, and you've hard-wired the cable too, which is good!
I've always loved high-end Sansui (and Onkyo) kit, as it's generally a cut above most other Jap gear :)
Marco.
Funny you should mention that... the temptation was MIGHTY strong to remove the IEC connector from the rear of the DAC19, install a little smoked perspex blanking plate and mains cord grommet, and wire the Belden straight into the unit itself. I may yet do this as the DAC19 is knocking my socks off and I can't see myself selling it any time soon. It is easily reversible anyway.
I'm a BIG Sansui fanboy... my father and I have a collection of around 60 units between us nowadays. Some of their gear sounds pretty damn decent (AU-517, 717, 719, 819, 919, AU-D11, AUD11 II, and the later AU alpha stuff. The big dedicated preamps and power amp models obviously speak for themselves.
The Japanese market saw some quite exotic Sansui gear never destined for overseas markets. Some of it is truly high-end stuff!
