Heyboer PT Question

MattPete · Post by **MattPete** » Sun Mar 11, 2007 11:51 pm

I just received my 100 watt Plexi kit, and the wire colors for the Heyboer PT don't seem to match what's on the CD.

The CD has:

B+
blue
yellow
blue

Bias supply
white
green

Heater Supply
green 16 gauge
green w/ yellow
green 16 gauge.

Here's what I've got (bold does not match):

blue
yellow
blue
white
green
green w/ yellow
black 16 gauge (instead of green 16?)
black 16 gauge (instead of green 16?)
red
red

OK, I figure the 16 gauge wires are the green 16 in the diagram. What are the two mystery red wires? Do I just cap them off, or are they important?

BTW: the markings on top of the PT say:
100 WATT PT
HTS-6010-80
022798

I think the two red wires were the higher voltage taps, the two blues being the lower voltage taps and the yellow the center tap (all for the high voltage secondary.) I know we've had a couple of other threads on this recently that would clarify it for you, but I don't remember exactly where they were.

The colors have changed since Mark's pic but you should be able to get the idea.......

I dont't know why I didn't find this last night -- maybe I was searching for "red wire" and not "red tap", but here's the thread that seems to clear this up: http://forum.metroamp.com/viewtopic.php ... +secondary

George is standardizing on a single power transformer that has the dual-voltage option. The reds are ~500v, and the blues are ~400v. If you don't plan on using the the dual-voltage option, then cap off the BLUE 400v wires.

edit: had blue and red switched, and I don't want someone to read this and use the wrong wires.

I was planning on putting screw caps onto the end of the leads and taping them to the inside of the chasis and out of harms way.
