Help: Velodyne SP1200 SUB problem

[Guest]

Archived from groups: rec.audio.pro (More info?)

Any one out there know about repairing these subs? (Servo 1200 - Velodyne)

My sub all of a sudden started a hum (ignoring all knobs and input signal)
and it 'clicks' every 2
seconds. Does anyone know what this could be symptomatic of? There's a
big-ass transformer inside going to the circuitry and I'm wondering if the
xformer died. I have no specs and I fear these things are impossible to fix?

Thanks
ps

The power supply is going into protection mode, possibly because the
output transistors are blown but maybe for some other reason. Get a
tech to look at it.

Transformers very seldom fail.

Thanks Scott -

I figure it's tech time - nothing smells or looks cooked on the board inside
making it even harder to diagnose. I wasn't even driving it hard when it
happened... like 20% vol playing GTA San Andreas :-D
