Thinking of buying used AVA equipment from another source? We can help you too.

Be very cautious when you buy used AVA equipment from an on-line auction or any other source where you cannot examine the unit firsthand. The sad truth is that some people lie. Call us first before buying our used equipment on the web or from other sources! We have excellent computer records of sales going back for years and likely we can promptly advise you of the authenticity of the product offered for sale if you will just supply us with the seller's name.

If you are contemplating the purchase of used AVA equipment from another source, we will examine, bench check, clean controls, jacks, and switches, and verify the performance of the unit for $50 ($100 for large power amplifiers) plus the cost of shipping. This inspection can be made before or after the sale, although it is obvious that you will have maximum protection if you have the unit examined before any money changes hands. We take pride in our work. One thing we don't want is AVA equipment not meeting our standards being offered as the real thing. We build very high quality and very reliable gear, and we don't want misrepresentative and abused items undermining our reputation.

Please note that the above offer is intended to be used for AVA equipment that has not been modified in any way. If you send us equipment that has been modified by someone other than AVA, special conditions may apply. Call us for details.
