Re: International Shipping: We ship internationally often and have yet to encounter a problem or complaint. We are very careful to test the equipment before it’s packed and then to double box the machine with added protection when needed for front panels, etc. We are not amateurs or an ebay store; we know these machines very well and know what it takes to get them to you safely. We use USPS priority internationally which seems to be the cheapest. If you prefer another carrier (you should know who delivers to your area reliably) please let us know. Also please be aware of any tariffs that you may be responsible for upon pick up on your end. International shipping may be expensive but we will make sure it is not a headache on top of the cost. PLEASE NOTE THAT SHIPPING INTERNATIONALLY WILL BE A MINIMUM OF $16 EVEN FOR SMALL PARTS.

ART Dual Tube EQ

Audio Proz Inv #: 40817

2 channel parametric tube EQ xlr 1/4 inch out. New item. I bought as many as I could get, not made now. Truly one of the best tube eq’s ever done. People don’t appreciate ART. People buy names, seldom truly excellent engineered products. I kid you not the new ART preamp and processor are better than the fanciest names. Compare schematics, open the units, listen honestly…

Aphex 109

Audio Proz Inv #: 40249

Parametric EQ w/tube essence, 2ch each with Gain, EQ, Freq, Bandwidth, Stereo or mono setup - Like New condition with box, packing, manual, etc. Decent design but the typical trouble which occurs is the controls age out badly, etc. They get loose and scratchy. I can fix this issue. I only sell low use things for this reason. Oddly not a lot of tube color in this design, the Aphex mic pre had more. I often refurbish old certain ADC, Sony, Radio Shack EQ, because of "cap and coil" design does effect vintage thickness (also because of single ended class A transistor design is like a tube character thing). If you need the best tube EQ, quality of controls, headroom etc., it's the ART Pro Channel (I own a few). 90db noise floor and it is really capable of wide or super sharp filters. It uses full size parts and pieces like old Yamaha and Tascam products. I can do a mod on this which allows honest variable tube harmonic level and phase. You can truly dial it in. See our ART Pro MPA Mic Preamp (has similar features).
