Bigger better porkier power supplies
2004-12-26 by Keith Pomfret
My two pence worth on the bigger better power supplies thing. I've not yet butchered any Analogue Systems kit but a set of home made racks running an assortment of Doepfer and ASol bits was close to the limit of the Doepfer supply on board one of the racks. I cast around eBay and picked up a couple of 'scrap' power supplies. One is a 3U rack (complete with fan) - vastly over engineered and with 4 modular supplies on board. +/-12 at an amp, +/-12 at an amp again, 5v at 6 amps and 24v at more than enough. This lump - which fits nicely into the bottom of my rack - cost me 15 quid. Another tenner got it tested, pronounced bulletproof and certificated. At the same time I picked up a server with 30 2Gb SCA/SCSI hard drives in it. I've taken it to bits and flogged ten of the hard drives. (which paid for it four times over). The rest live in the 'it'll come in useful' pile and the power supply (the requisite +12-12+5 industrial strength computer sort) promises to be on hand in case I ever need another one. THe 3U supply is running a couple of Doepfer racks and I've still yards of headroom to build and populate more racks Cheers for now Keith P
