![]() ![]() Even after you go through all the trouble, you're still going to be left with just a single preamp, not a dual. Also, there is a ton of other circuitry in there that gets in the way and is unneeded after the mod, you're for sure going to have to replace all the power supply capacitors anyway, etc., etc. These were constructed on now crufty old first-generation PCBs that are prone to traces lifting from accumulated moisture, and are not particularly amenable to modification. And this is before the mod process, which turns out to be not at all straightforward. You can easily pay $1300 or more for one on fleaBay, and what you get will be in uncertain condition. First, the Ampex 351 is now highly sought after, and prices for these units have skyrocketed. So why not just mod one of these, and be done? Well, it turns out that there are a number of good reasons. In fact, there's a fair amount of documentation online (especially at the Electric Audio forum, courtesy of Greg Norman), describing how to mod one of these units into a preamp. One of the preferred platforms for the mod community has been the amplifier from Ampex 351 reel-to-reel player, as shown above. As a tube aficionado, this makes perfect sense to me - in a world now flooded with sterile-sounding ultra-low distortion preamp choices, more and more musicians are realizing that a bit of distortion, of the right kind, can be just the ticket for producing a warm, full sound. In any case, Andrew is a big fan of tube microphone preamps based on modification of old Ampex reel-to-reel players. However, with Thursday currently on hiatus, Andrew has moved on to audio engineering, and is currently located in Auckland, New Zealand, where is an audio engineer working directly with Neil Finn (of Crowded House fame) at Neil's well-known Roundhead Studios. This mic preamp was commissioned by Andrew Everding, perhaps best known as the keyboard player for the band Thursday. Hope to document a fairly complete build log here.
