HP41 CX Speaker Cable connectin to board
Message #1 Posted by raudzus on 26 July 2007, 6:30 a.m.

Hello,

I'have a HP41 CX build in 1987. The speaker inside is fixed inside on the backside. When I opened the HP41 the two cables of the speakers are brocken. Can you tell where I must connect the speaker cables on the board. Many thanks. Greetings Dieter

Hi,

Please take a look at:

http://www.clonix41.org/Maintenance/hp-41_PCBs.htm

You'll find Halfnut board on the left-bottom of this page, there is a "big" brown capacitor (center bottom of the board) and a couple of pads to the rigth of said capacitor (between the cap and the [hp] logo on the board)

One of these pads is square (the rightmost) solder the black wire there, and the red wire to the round pad.

Hope this helps.

Diego.
