After searching for this for a long time and finally finding one I have changed my plans yet again . It does not have the original cover as it was flush mounted in a custom install however it does have a custom made Plexi cover with XTANT written on it. The EQ is in excellent mechanical condition however the Plexi cover needs a good polishing (no deep scracthes just a few scuffs/smudges) and it has a few tiny nicks in the XTANT lettering. I don't have the owners manual however you can download it below to check out the features. The manual is for the P500 however this is a P500"A" which was a later "upgraded" version. I can't remember exactly what the upgrade was but I think npdang may know (some kind of noise reduction circuitry I think?)
Asking $150.00 shipped to the US by way of Confirmed Address PayPal only (unless I know you) and I'll cover the fee. No trades needed at this time but let me know what you have and I'll consider it . I'm sure a few guys here can vouch for me and I have numerous references at www.elitecaraudio.com as well as 240+ 100% positive on eBay under mrmarvsplace.
BTW, I will ship anywhere as long as you have a Confirmed PayPal address and are willing to cover any and all additional shipping costs/fees/duties etc.
I will post pics as soon as photobucket will let me in however if you are seriously interested and the only thing keeping you from buying it is seeing pictures I will send them to you if you send me your email address.
