Info wanted on OPT....

nickds1 · 03:34 PM

I've just been given the OPT from a Velleman K8011 monoblock amp - its a toroidal BEAST (90W). Its marked "ZD 043".

The Velleman manual is at http://www.velleman.eu/downloads/0/manual_k8011.pdf

Does anyone have the spec for this xfrmr?

Cheers

It should be a type ZD043

Primary: 2 x 1K, taps at 1/3
Secondary: 4 and 8 ohms
90W max

bandwidth: 2Hz to 125kHz (-3dB/1W) (probably with feedback applied)
