Triad Audio L3 power supply - Page 2

post #16 of 22

^ The Lisa III was the same way, When I bought my Lisa III XP it sat for 3 months until I bought the LLP

Both of these will work yes, However I have been using this low cost AC Adaptor on Both LISA III as well as the L3

That is the same size as the one in the following link also. I'm not sure if it is exactly right but it is the best that i've found.

I found this next one because of Sceptre's post above. I really just want to charge the battery. Is there really an advantage in buying this for that purpose?

Hi man, which PSU that you finally end up ?
I found this one in my neighbour garage sale http://www.master-instruments.com.au/products/57901/MP3037.html

I wonder if with the red dot it means a center positive PSU that Lisa III XP require ?

I am confused. Should I plug the + to the + pin or the other way around + to the - ?

I'll check my configuration tomorrow. Don't want to guess and get it wrong. I would always put a multi meter on the plug to check V and polarity. I'll put details of my eventual PSU which I picked up brand new for a song.

Cool, thanks man.

So I guess, in this case I will need a multi meter.

Put the Red one inside the hole of my adaptor and the black one on the outside, if I can see the Voltage reading / meter pin moving then it is Center Positive as needed by Lisa III XP amp ?

Is that correct analogy ? at the moment I do not have multiMeter with me.

OK,

 

I can confirm that it is 24V + tip. 

 

Your methodology of using the meter is correct as long as you see positive 24V when red lead is in centre.

 

Confirmation of correct connection will be blue led lit on front panel when switched on.

 

The PSU I mentioned was teh Balluff BAE001 24V 750mA regulated supply.  It is desgned as a rack mounted unit but works fine for me.

 

Hope all goes well and you start enjoying your Lisa III.
