DIY HV CRO probe

What would be the most cost-effective way to protect my Tektronics TDS
digital oscilloscope from possible damage by 2-3KV audio signals? It
is rated for 300VAC input max.

I don't need to measure the frequency or voltage, only check the
waveform for distortion without blowing my CRO.

Regards,

Larry
