Here is a like new PMA5000EX Audio Panel for sale. Works perfectly. I wanted bluetooth so I replaced this with a PDA360EX. If you can make a bluetooth connection to your headset, you will be perfectly happy with this advanced audio panel. I'm seeing $800 prices on this on eBay and other resale sites. I'm offering this on VAF for $600.
I'm including the rack, backplate, and all connectors with the audio panel.
So, $600, you pay the shipping.
