Here is a great Stephens Electronics 2416 console from the early 70s. Its on ebay for a rather hopeful $50,000
From the ebay text:
First, if anyone is seriously interested in this console please call or email me directly - there is simply too much information I know about this console to type it all in an ebay listing. John Stephens made approximately seven of these consoles any only two are known to still exist. This is NOT a Stevenson console, do not be confused, this was handmade by John Stephens of Stephens Electronics in Burbank, CA. David Kean at the Audities Foundation has a larger one (48 input channels) and I have the other (24 input channels). The last photo is of the Stephens 2416 console owned by David Kean/Audities installed in the 1970's at Premore Studios in North Hollywood. Mine was never installed but was obtained by David Kean from the estate of John Stephens when he passed away several years ago. The console was saved from the trash by Doug Messenger @ harddrive studios in LA (who owns the Stephens 821B used to record Pink Floyd's "The Wall") when Premore Inc closed its doors after the death of Leo Hulseman of Solo Cup Company (who originally commissioned the consoles from John Stephens for an excess of $70,000 in the early 1970's). When John Stephens was still alive he bought the console back from Doug Messenger and it sat unused in his workspace until he passed away.
Portable (Less than 100 lbs) - Main Section is in a road case that measures 49"x29"x6", Master/Monitor section is in a case that measures 25"x17"x6". Both cases can be carried by one person.
All discrete point to point circuitry using the same proprietary 618/620 amplifiers used in the 821B tape machines.
100% hand made and built by John Stephens himself.
-24 Microphone preamps with UTC ouncer input transformers and direct outputs to TT patchbay
-24 Line inputs
-18 Busses (10 primary, 8 secondary). Unique sealed flip switches for quick buss assignment.
-2 Sub Master Groups
-2 band passive inductor based EQ on all input channels with Stephens 621 makeup amplifier.
-Two large inductors for each channel. All eq controls are gold plated stepped switches.
-High eq selectable: 10K, 5K, 3.5K, 1.5K, .88K.
-Low Eq selectable: 50, 100, 200, 300, 500.
-EQ in/out switch, Solo switch. Channel On/Off Switch
-600 ohm P&G faders (primary outputs), Allen Bradley pots (secondary outputs/master/group outputs)
and more...depending on how you configure the console.
-12 Master Outs
-3 Headphone Outputs with 16 inputs on each for custom headphone mixes
I am currently only using the main section, which by itself is a complete 24x2x16 mixer (8 primary outputs, 8 secondary outputs, 2 subgroup outputs/master outs). The master/monitor section is useful if you want to use it as a master section, create headphone submixes or alternate mixes to different speaker sets, sends, and so on - it could also be used as a standalone 16x12 channel line submixer. Some features have not been implemented that could be implemented if you need them, please call me to discuss. The console has been in use in my studio for three years. I've restored the console completely with new audio grade high temperature, low esr capacitors and made it 100% functional despite limited documentation. The company that made the first set of fader panels for me did a bad job and I will cover the cost of new fader panels and help with the install of the console for the new buyer. Whomever buys this console should be willing to learn about the console design and have basic technical knowledge or capability. Since the console is essentially one of a kind I want to make sure whomever buys the console knows how it is built. Included is the smaller 3M 16 channel VU panel and the original, and larger, Stephens 16 channel VU panel with large Modutec VU meters. I also have many spare 620 amplifier modules, rare schematics, and documents including the console specs. I am currently using a 10A regulated HP power supply which supplies the 618 modules with -38V for tons of headroom. I had new metal EQ frequency select switches made since the original plastic ones needed replacing - and they are perfect replicas of the originals but metal so that they will last forever. As you can see from the photos some of the gold switch caps are missing - but I don't know where to get replacements. That said, it's purely cosmetic and not functionally problematic.
As one would expect the sound is hifi, pure, and second to none - anyone that has heard his tape machines knows that nothing compares to the sound of a Stephens. One of the great pioneers of recording technology, John Stephens was a genius and rarely gets the credit he deserves for the beautiful recorders and consoles he designed.
