DJ Needed to test my Yamaha PW800W Backup Power Supply

Marysville WA

Description

I recently bought a Yamaha PW800W backup power supply at an estate sale for a bargain price because the seller had no way of verifying that it works. The only way to test it is with a Yamaha CL1, CL3, CL5, or PM5D mixer board (maybe others). If you can help me, I will come to you and pay $20 to test it. If it works and you want it, I'll sell it for $220.
