API Vintage Channel Strip 312 550wa 325 Melville Wally Heider Amazing Rack. The pre-amplifier is a custom made 312 with a vintage API 325 card and a vintage API 3164 input transformer from an original 1604module we got from audio guru Avedis. The amplifier is amazing flat 10hz to 20k and up. Beautiful example of a real vintage Api full frequency amplifier. Truly beautiful and smokes modern version.
2520s are Farmingdale all card components are correct and transformers are original. We got these as part of a rack of 16 build by Wally Heider and Frank Dimideo for remote recording the Greatfull Dead.
They have several unique features and mods done by Dimideo. They are not as exact as 550as but more musical sounding and when they are pushed they open up.
One has lost its Wally Heider badge but we have the number it was written down. The second badge is photographed. The Serials are close and they both look identical. Original 2520 were Studio Systems which are the worst, noisiest and prone to failure of the vintage 2520s and these have been replaced with current 2520s which sound and function perfectly. We have many equalizers in our 1608 but these occupy all the important always used channels.
525c Limiter Compressor matched to within a db. Dim Lights replaced with very cool LEDs.Units are super clean and sound from transparent to big saturation. Classic compressors from the greatest era of gear and design; these have been used on countless classics. Great as buss pair, on overheads on keys, vocals, bass. Within a few serial numbers, these came to us from a great LA CA facilitys gear room two decades ago.
The 525c is the best of the 525 design and really the best API Audio made. The Alctron Racks have a very cool feature that allows you to internally patch the channels. Beefy power supply runs both units well. All checked by SVT Audio and functioning 100%. Plug and play a level vintage audio.
These modules do not come up often any more because they are all rare and because they are the API sound. Look at our other listing for more great gear.
