Lightshow 331 Type 1 vs. Type 2 - Help?

[johnhall]

Graham's is most certainly a "Type One" model. His power supply appears genuine, except that the low voltage cable, plug and socket have been replaced.

The DIN plug and socket on these was a fairly obscure one, difficult to match exactly.

The power supplies on these are both 18 volts but the type One didn't require as much current and the connections were on different pins to preclude using the incorrect supply. However, it's easy to make a universal supply by choosing a transformer that's capable of delivering a minimum of about 30 watts, connecting one side to pin 5 of the DIN plug and the other side to pins 1 and 4.

The originals did not have a fuse and the input diodes probably provided a rudimentary fuse function, but it certainly would be cheap insurance to put a fuse on both the input and output side of the circuit.

Thanks Mr H.

Thanks much to all. I now have everything working.

The 'new' transformer box, total cost was about $15:


Go figure, you get the right power into this thing and it lights up, and now the dimmer knob actually does something.

That's a great result, John. We now know that the lights work, so how does it play? Are the lights distracting at all?

FWIW, my 331 plays like The Truth, baby - really slim neck and great for any style.

The lights aren't the least bit distracting.

Baby? Kenny, I hardly know you!!

Surely you can't be serious!!

[kennyhowes]

Everybody calls each other "baby" in New Orleans!

I know, I know, I'm not there anymore. Some habits don't go away.

And don't call me Shirley.

I also find that the lights are not distracting, they just add to the "ambience" of the 331LS ...

Which is better (or worse) - baby or dude? Being an Aussie, I have to say that 'mate' is starting to give me the irrits! It's OK if he is a mate, but a total stranger?

Love that word "ambience"!!
