Restored and racked by one of the designers of the original Focusrite Forte console at Master Rock in London. They have added independently switchable +48V phantom power. Like all Helios modules these are designed to produce an unbalanced output. This has been balanced using high-quality transformers, and an output attenuator allows the preamp to be driven hard if you wish.

History and Specification:

Capital Radio in London was a Helios customer from the early 1970s. They had at least one large-format Helios console, as well as a number of small ‘emergency warning mixers’ that were installed at remote locations around the city in case the Thames Barrier failed!

In 1979 Capital wanted to refit their studios in the Euston Tower, and commissioned Helios to build new mixers. Unfortunately, Helios went out of business soon after starting work on the project. To recoup their costs, Capital sent their engineers to the Helios factory to salvage as many parts as they could, including these mic input channels. Capital then asked Tweed Audio to build a new Master Control Room console that incorporated the Helios modules. This was completed in late 1981 and decommissioned in 1997 when Capital moved out of the Euston Tower premises.

All Helios desks were custom-made to the buyer’s specification, so no two are the same. These modules have the classic Helios mic preamp circuit with the Sowter 3374 input transformer, but they also have several unique features:

* They are the only known Helios mic channels with a built-in compressor — a very versatile and good-sounding design based around the dbx 202 VCA chip. Attack, release and ratio are continuously variable and threshold is controlled by adjusting the preamp gain. It’s possible to achieve massive amounts of gain reduction if you want! The compressor can also be switched pre or post EQ.

* Nearly all Helios modules use 24V and 0V power rails, but these run off +18V and -18V. This means they have more headroom and can drive a line-level output without an additional gain stage.

* The EQ design is similar to that found in so-called ‘Type 78’ and ‘Type 79’ Helios modules, but the outer bands are shelving rather than peaking. All controls are continuously adjustable including the low- and high-pass filter cutoff, and they use centre-tapped pots so the centre position really is ‘zero’.

TESTIMONIALS

"Just received my Roland RS 505 Paraphonic! Thanks so much - arrived very promptly, well packaged, in great condition and sounds amazing! Best seller."

Koko Hiras

"When you are spending big money of vintage gear it's nice to have the confidence of impeccable service, sales and support... some of the best in the industry! Impeccable people, incredible equipment… my poor poor fiancé"

James DLR - Sofa Sound/Metalheadz

"Soundgas provided the absolutely top service in terms of item quality as well as service and communication. Shipping was fast, packing was top notch. These people deserve the best reputation they already have. Many many thanks, guys."

Dupille Luc

"Still in shock! Can not believe how good the seller is. This product was inspected, and shipped from the UK to the USA quicker than orders from my home state. Highly recommend these guys."

Thomas Tedesco

“If you are a vintage audio gear head then this is the place you have been looking for all your life. Pretty much any piece of classic or obscure kit that you are after is available here... But the clincher for me is that the gear they sell has been restored by their top techs (unless otherwise noted) which is really very important when dealing with, for example, synths from 30 years ago.”

Lincoln Barrett / High Contrast

“I have bought two Moog synths from Soundgas over the past year, and I cannot say enough wonderful things about their selection of vintage products, the level of service, diligent responses to email, and expedient shipping with copious protective packaging. Soundgas is an impressive operation. My synths also sound amazing! These folks have made my vintage keyboard dreams come true in short order!”

J Yates

"Soundgas has an unbelievable selection of the cool, old stuff that’s hard to find. Tony knows his stuff and goes out of his way to make sure the transaction is a smooth one. Thanks guys!"

Tucker Martine - Flora Recording

"Soundgas offer a great service, sourcing esoteric gear that works great."

Tom Rowlands - Chemical Brothers

“The Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”

Julius Bonson

“If not a new language, then at least a very challenging, old dialect that will take me some time to assimilate. I’ve been waiting a long time for the challenge. Thank you @soundgasltd, she’s a beaut...and nobody prepares and packs like you fine folks.”

Justin Meldal-Johnsen

“I purchased a completely overhauled vintage valve Binson Echorec 2 T7E modified with varispeed, wet-only output, and a new paint job from Soundgas in early 2018. Tony and his team did an amazing job during every step of the purchase”

Matt Morton

“The perfect place to hear, learn about and then buy your most wanted piece of vintage music gear! I've not only managed to buy a rare piece of equipment I really wanted, but I have the guarantee it's been serviced, and I got it from people who are clearly passionate and knowledgeable about what they do, as well as super friendly and responsive by email. Thoroughly recommended!”

Colleen / Cécile Schott

"DREAM. COME. TRUE. My music has taken me around the world a few times...and if you are like me and absolutely adore vintage gear...Soundgas is the stuff of LEGENDS. It's the shop that people like us search for our whole lives- fantastic and rare selections, and the technical know-how to repair and or mod these vintage items to get them into shape to flow with your modern setup."

Tom Gossin

“I’ve bought a number of items from Soundgas recently, and have been really impressed with their service. It takes the stress out of buying vintage gear to know it’s been properly (and faithfully) serviced or restored. Their after-sales service has also been exemplary. Highly recommended.”

David Wrench

“Imagine the perfect eBay.... with everything you never knew you wanted… and you can rest assured that your vintage and rare wobbly sound device will turn up on time and in one piece and possibly in even better condition that when it left the workshop. Soundgas - literally amazing."

Josh Lloyd-Watson & Tom McFarland - Jungle

"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."

Matthew Herbert

"Excellent equipment, wonderful service. I fully recommend Soundgas to anyone in the vintage gear market and I will definitely be a return customer. The gear itself was exactly as advertised and in great condition."

Hallam Kite

"The packing job to get it over to the US was superb, and the sound and performance of my Space Echo exceeds all of my expectations. I hope to do business with Soundgas again in the future. Many thanks!”

Rhett Daily

"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."
