Calling all SL-1200/1210 owners!

[Peter Stockwell]

there was a flat black & white cable running from the back of the deck (connected internally) fitted with a flat-pinned two-pin plug on the end that connects to the 'sense' socket on the back of the KAB PSU,

That's the "original" US two pin mains lead and plug.

and a small thin grey DC cable supplied which connects on one end to the underneath of the deck and the other to the 30V DC socket on the back of the PSU.

That's the cable that I have to solder internally, it doesn't look too difficult, but I don't have a couple of calm hours to do it yet. It connects to the Bridge rectifier after the Technics transformer. The deck doesn't even have to be fully dismantled to do it.

Indeed, there's a decent mains cable with the PSU, no fuses here teehee

Your deck is a 110v 60Hz model, anybody that buys a KAB psu in the states doesn't have to ask themselves any questions. Kevin got back to me about the socket and I don't actually need to connect the "sense" socket for averything to work. I'm going to the US in december, but maybe a US based member would be kind to send me a 2 pin plug?

cheers

So your deck didn't come already fitted with this? If not, I don't understand why because that's the connector you need to plug into the 'sense' socket on the PSU...

Sorry for being dense but I'm still trying to get my head around what's going on...

With mine there is a DC socket the same as on the KAB PSU on the underneath of the deck, so all you do is plug it in.

LOL. Well, as you know, I use a hard-wired Transparent Reference Powerlink mains lead (which costs nearly as much as the deck itself) - that doesn't have any fuses either

The supplied lead is just a spare.

Is it? I wouldn't know. All I know is that I specified the UK mains version (220v) KAB PSU so that it would work on UK mains. How can the deck be 110v and the PSU 220v?

Kevin got back to me about the socket and I don't actually need to connect the "sense" socket for averything to work. I'm going to the US in december, but maybe a US based member would be kind to send me a 2 pin plug?

I still don't understand why you weren't supplied with the right plug in the first place...

What came with the deck?

I've only gone and trashed my 103pro haven't I... 'kin knuckle dragging neanderthal that I am - tried to clean it having had a few tinnies. It's off to Expert Stylus for a re-build now.

Marco, interesting to read the thoughts on the back of the SP10 v's KAB 1210 comparison, the little brother did itself proud! How are you getting on with the SUT / head amp, which one has been on duty lately?

[Marco]

Feck what a nightmare, mate! Well I suppose you were going to have it rebuilt anyway with a new stylus profile...

Let me know how you get on

Yep, little brother certainly did do himself proud. There will be more on this later on the Chesterfest thread once Steve posts the pictures.

I also had some other interesting discoveries at Chester regarding mats and the A23 versus the HA-500 head amp thanks to the help of other experienced ears, so stay tuned!

Marco.

Cool [rubs hands in anticipation]

Marco's a technophobe, innit ?

I bought a 2nd hand SL1210 euro spec in France, it comes with a 2 pin euro plug, in the UK it would have a 3 pin MK plug. It's got the transformer wired to accept 230v (220 to 250 actually) and then pass a reduced voltage to the internal technics PSU. Normally, a bridge rectifier converts the positive and negative cycles of AC to DC. After this there's regulation and smoothing to take out the now 100Hz ripple on the DC. The Kabusa PSU output connection has to be after the transformer and before the bridge rectifier. The bridge rectifier will make sure that the DC output of the KAB PSU is the "right" way up for the rest of the electronics.

With mine there is a DC socket the same as on the KAB PSU on the underneath of the deck, so all you do is plug it in.

That's very nice, and is a "value addition" of the KAB modified SL1210

All I know is that I specified the UK mains version (220v) KAB PSU so that it would work on UK mains. How can the deck be 110v and the PSU 220v?

That's easy, when you plug your PSU into the KAB1210 your supplying DC to the electronics after the original transformer. So the issue of 110v or 220v no longer arrises. Very often, kit has the same transformer for 110v or 220v, however the transformer has 2 sets of 110v windings. They're connected in parallel for 110v and in series for 220v. Most kit is easy to convert between the 2 (japanese market kit is different, tho', usally it's 100v)

I still don't understand why you weren't supplied with the right plug in the first place...

What came with the deck?

The deck has everything it needs in standard form for a Euro model. The KAB psu was developed as a US market product. The KAB PS1200 works perfectly with a KAB'd 1200, coz as I pointed out it's easy to switch between 110v and 220v and the KAB 1200s take DC into the very nice KAB socket that you have. The original lead then completes a low voltage (5v) sensor circuit that detects when you've opened or closed the on off switch. Kevin has told me that bare wires in the Sense socket will work just as well.

So any of this help ?

cheers

[Marco]

Yep, all is now clear. I'd forgotten you had bought a second-hand 1210, and thought you had ordered a new one from KAB

Hence my being perplexed at why you didn't have all the right connectors already fitted!

I blame senile dementia

Marco.

wot, Margaret Thatcher ?

[Marco]

Hehe...

So what's the current state of play on your fitting of the KAB mods?

Marco.

On hold, I live in a small appartment and I have visitors. Sunday, I'm going to have a closer a look at what I'm going to call KAB stage 1, fitting the power supply cable. As I said it looks pretty easy from the pics supplied with the PSU. It'll stay in stage 1 for a while, I think i'm going to get J7 to fit the KAB tonearm wand and attach a suitable phonocable.
