Kevmo Posted August 11, 2013 Share Posted August 11, 2013 Left/lost it at a gig the need quick replacement for roland vr09 PS Please help ASAp Kevmo Link to comment Share on other sites More sharing options...
rien Posted August 11, 2013 Share Posted August 11, 2013 The original part from roland has model number PSB-1U. The VR-09 power supply outputs 9V DC at 2A (18W), connector is a standard barrel type with center pin negative. Since there are many sizes of "standard" barrel type connectors: external diameter is 5.5mm, internal diameter 2.1mm, plug is 10mm long. You may be able to find a replacement power supply that suits your need at a good electrician shop, or a shop that sells electronic components specifically. Maybe even one of those one size fits all power supply at the nearest drugstore. You need something that can handle 2A or more (although that seems quite high, i bet a 1A power supply would be sufficient), outputs 9V and whose plug is wired the same.

rien Posted August 11, 2013 Share Posted August 11, 2013 something like that should fit (buy at your own risk), the specifications matches: http://www.alliedelec.com/search/productdetail.aspx?SKU=70231059#tab=overview The exact same product at digikey: http://www.digikey.com/product-detail/en/WSU090-2000-R/237-1426-ND/3094952 Nothing suitable in stock at mouser... Otherwise, did you try calling Roland ? They may have a PSU in stock to send with an express courrier... Link to comment Share on other sites More sharing options...
WesG Posted August 11, 2013 Share Posted August 11, 2013 Try also Newark, mouser, and digikey for suitable PS that can be delivered overnight.

Reezekeys Posted August 11, 2013 Share Posted August 11, 2013 Radio Shack has "universal" adapters with interchangeable tips to fit most devices. Pricy but who in the USA doesn't have a Rat Shack nearby? Link to comment Share on other sites More sharing options...

smanzella Posted August 11, 2013 Share Posted August 11, 2013 Be careful if you buy anything other than the Roland replacement power supply. If you buy a third party power supply, make sure that the voltage is the same, it has the same amperage or more, the barrel plug is the correct size, and that the power supply is regulated so that you are insured that the voltage does not float high or sag. Hope you find this helpful. Yamaha CP-73, Hammond SK Pro 73, Yamaha MODX 7, Roland Fantom 06, Roland VK-8M, Yamaha FS1R Link to comment Share on other sites More sharing options...

I had a somewhat similar experience when I upgraded from an Edirol PCR-M80 keyboard to my current A800 Pro. I didn't bother buying an AC adapter for the A800 since I had one for the M80. Same voltage, current, and the connectors fit perfect. Except for one minor detail they reversed the polarity (I found that out at the gig)! Luckily, since the A800 is able to be powered by USB, I just hooked up my iPhone charger. Worked great! Unfortunately it looks like the VR09 can't be powered that way.

SynMike Posted August 12, 2013 Share Posted August 12, 2013 Losing a power supply sucks. Roland and Boss use the PSB-1U for many products; It is their most common model. I have several that came with my Boss pedal board, my VR-09, my Gaia, and I think my Edirol FA-101. You might even find a local Roland dealer that has it in stock. At least you can run the VR-09 on batteries until you get the replacement.
