Sooner or later we will complete the overhaul and modification of one of these. If you’d like to know more please contact us now…
Unique super-rare disc echo with our super-slow varispeed modification. Has had a total mechanical/electrical rebuild – many hours over many days on Doctor Huw’s operating table.
Working very well and sounding spectacular. Demos of a previous unit below.
Full set of photos and demos of this machine to follow – it’s undergoing final calibration and will be thoroughly soak tested and tweaked over the next 2-3 weeks. Expect delivery by mid December.
The super-slow varispeed motor option offers the full functionality of regular speed uses, but with additional super-slow speeds for longer, darker, dirtier repeats. This can get properly gnarly when pushed into distortion at slow speed – it should be noted that at the slowest speeds very little fidelity or feedback happens – this is for special effects only rather than regular use.
Can be further modified with jack output (instead of DIN socket) and wet-only output option; has an IEC mains socket.
The below info and demos are from a previous unit we sold:
These are incredible and very complex machines – germanium transistor-based – with many components across several boards that have now drifted out of tolerance. As long as the disc surface is good, it’s possible to get them running reasonably well with a couple of solid days’ work, but as nearly all the caps and transistors are steadily-failing, it’s only a matter of time before you’ll need to dive back in again and change more components. The only way to be as sure as possible of reasonable reliability is to change pretty much every component on every board. Fortunately for the next owner, Doctor Huw’s a perfectionist; he’s spent a great deal of time working through each circuit, painstakingly-matching transistors and replacing caps. The result of lots of incremental gains is truly-stunning: this is a superb vintage echo that stands next to the very best in our studio. The additional time developing the super-slow varispeed mod has been worthwhile – it’s a stunning effect.
I’d been searching for a Dynacord Echocord Studio for years, and after picking up a couple it’s taken many more months for us to find time to get one working and ready to sell. The price does not reflect the amount of time that has gone into the rebuild, and the hours of testing and tweaking to get this machine to run as well as it can. But it’s a point of pride that we can resurrect a rare and fascinating machine like this and get it back out in the world making music .
As you can see from the pictures and demo the basic principle is a series of heads resting above a spinning disc metal disc, attached to which is a ferrous oxide-coated recording surface (not unlike a floppy disc).
We’ll add more information about the controls and technology driving this amazing piece of kit as soon as we can but if you have any questions please get in touch.
UK/EU 220v unit.
Superb cosmetic condition with only a few very minor scuffs showing up across the unit.
For sales in UK/EU, this item is on the margin scheme for second hand goods. VAT-free sales are not possible for this item.
220/240v unit. A step-up transformer will be required for use on 110/120v supplies. Please ask if you need advice on what to use. We do not recommend using cheap, generic Chinese mains transformers.

This Dynacord Echocord Studio has spent a couple of weeks being completely overhauled and rebuilt in our workshop. It was a basket case, but the Doctor has made it a labour of love: almost every transistor and capacitor has been carefully replaced to bring it up as close to factory spec as possible: lots of small gains that steadily add up. The heads have been polished, the mechanics rebuilt. The only thing we couldn’t improve is the disc. As a result, it sounds truly stunning. I doubt we could sell it for what it’s cost us in tech time, but we’re proud of being able to bring this fabulous-sounding echo back to full working order. Someone’s going to have a very happy Christmas. In other news we just finished a thorough rebuild on an HH Slider Echo. Looking forward to the test bench tomorrow...
I'd heard whispered rumours of a Dynacord echo that with a flat spinning disc instead of tape, but as my searches yielded no further information, I...

“The Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”
“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”
"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."
"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."
"Just received my Roland RS 505 Paraphonic! Thanks so much - arrived very promptly, well packaged, in great condition and sounds amazing! Best seller."
"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."
“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."
"Soundgas offer a great service, sourcing esoteric gear that works great."
“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.”
"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!"
"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."
“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.”
"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."
“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.”
"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."
“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!”
“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!”
"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"
"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!”
