Over the years, I've been approached by customers who either lost their power supply or obtained a second hand WA-47 that they wanted to send in for modification but lacked the power supply. I've had to make a couple 'one off' or modified-off the shelf power supplies to fit the WA-47, as well as to make a few replacement cables. This, along with the already comprehensive modifications we do to the WA-47 power supply led us to where we are here. "What if we took this to its highest level?" Thus our own replacement WA-47 power supply was born. Using only the best components from end to end, We set out to improve the WA-47 supply in every way that makes sense, starting with a more rugged steel enclosure and using a higher quality insulated rotary switch, reinforced and fitted with a custom resistor ladder PCB, and our own custom 20ft Gotham cable fitted with IP66 connector on our end and a Neutrik 7 pin XLR on the WA-47 end. We used only the highest end components throughout, including our own custom made Sparkos Labs discrete regulator for filament supply, and a heatsink so ridiculous that the PSU now literally runs 'cold' and can run forever without producing heat. We improved upon the existing fixed discrete circuitry, adding bypass capacitors where appropriate and a low level bleeder resistor circuit on both voltage rails to ensure safety, so that the unit will safely discharge over time even if disconnected and put away in an improper order.
We're very proud of this replacement PSU and happy to add it to the Signal Art portfolio of handcrafted products. I would like to stress that this PSU is intended for those who do not have a PSU for their beloved (and hopefully upgraded) WA-47 microphone. If you have an existing PSU and it needs to be fixed, please have it fixed (by us or the manufacturer) and if you have sent in a WA-47 complete system for upgrade, then the modifications we do to the WA-47 PSU already get you most of the way there. This product is really intended to serve those who lost their PSU and need one to get their system back to working order.
We will be launching the upgraded PSU to the WA-251 up next, and will go from there to see if there is a demand for further power supplies. Enjoy!
