Heatsink required?

MIDIbox SEQ
1

Firstly, oh my oh my! What an awesome sequencer!

This Sh#ts over all other sequencers i’ve owned & used.. This is totally incredible.. Hats off to all involved.

With my LCD backlight as low as possible, the regulator is getting too hot to touch, so i’m guessing a nice fat heatsink is gonna be required?

I really want the backlight at max.. so I was thinking of taking another tap off the multitap transformer and rectifying + smoothing + regulating it for the backlight.

Is this the norm? or should i be looking for a fault somewhere?

(Everything is working perfectly, as far as i can tell)

Much regards

Mike

Hi Mike,

indeed, I must agree. The MBSeq is the most remarkable Sequencer I have ever used!

re: the heatsink, I found that running the 2 LCDs and the LEDs meant my regulator got so hot that it cut out after 10 minutes or so. After some forum suggestions, I mounted the reg. on a pretty thin heatsink and can sequence almost all night now :slight_smile:
