The title kind of tells you a lot of what you need know with this one! And it delivers - sounds great rich reverb and plenty of valve/tube character.

Serviced and complete with a new custom power supply (240v).
Tube Works RT-921 spring reverb for sale in full working order. It’s a high quality 1U rack unit, designed by U.S. amp & pedal builder B.K. Butler (it’s got his name on it!) and also known as the “Real Tube Reverb”.
It’s a solidly-built, quality piece of kit with great tone.
Service work included replacement of the output pots and one of the tanks. See below for some of the tech’s report on this, and also the replacement power supply.
“A lot to do here. Some very bad pots, one beyond help. As these are the multiple detent type which I can not get hold of, I have replaced both the output level pots with regular ones so it is still symmetrical, so to speak.
One of the tanks had a very low output, for reasons unknown. They usually just fail rather than do this. New tank fitted. This is the correct spec, but as it is new it doesn’t sound exactly like the remaining original one, mainly in decay time, which is slightly longer. I don’t think this will be a major issue, in fact it gives a subtle stereo movement in the reverb tails which is quite pleasing.”
POWER SUPPLY: “PSU built with correct spec but valve heater supply was not even slightly enough to make the valves work properly so this needed modifying. Either the official power supply was very different to spec or someone has perhaps modified this unit to work with a higher voltage supply. Who knows, but it works properly now. This unit should only be used with the custom power supply provided.“
In very good cosmetic condition with some light scuffs and signs of wear. See photos for more information on cosmetic condition.
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.
“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."
"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."
"Finally, a company that tracks down all those brilliant curiosities that bring so much character and personality to a studio."
“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”
"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"
“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.”
"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."
“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.”
“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!”
"Soundgas offer a great service, sourcing esoteric gear that works great."
"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!”
"Packed with love and care. A stampede couldn't have crushed this thing. Works great and sounds like a dream. I love you Soundgas."
“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 Space Echo made its way to me - it looks and sounds beyond dreams, thanks guys for your great service and communication.”
"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."
“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.”
"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!"
"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."
