IanA Posted October 13, 2013 Share Posted October 13, 2013 (edited) Up for sale is my 1 Spot single 9 volt power supply, have used it just a handfull of times! Comes with the original box, is less that 12 months old and in great condition. Can be used to power several pedals at once if you have a daisy chain, if you don't then I have a fairly new EBS daisy chain that I can throw in for £5.00 exta Am looking for £15.00, you can either collect from Leicester or I can post to a UK address Thanks for looking Ian Edited October 15, 2013 by Iana Link to comment Share on other sites More sharing options...
sifi2112 Posted October 14, 2013 Share Posted October 14, 2013 I'm interested mate, how many pedals with daisy chain ? Pls pm me your details, cheers Si Link to comment Share on other sites More sharing options...
TWILITEZONE Posted October 15, 2013 Share Posted October 15, 2013 (edited) how many pedals depends on the pedal requirement and the one spot capacity, measured in milliamps. So if the onespot is rated at x milliamp output, as long as the [u]total[/u] pedal requirement (all added together) is below this, it will be fine. Just to be tricky, some measurements are given in watts. The calculation is volts x amps = watts. We know the volts is 9, so to work out the amps, divide the watts by 9. (1 amp = 1000milliamps). sorry afterthought. The previous info only deals with the power consumption calculation. Actual use depends on particular pedals, all modern ones have standard coax connectors with centre negative and are (electronic) noise suppressed, so no problem. some older ones (check on the case or spec) have a centre positive connection which is ok if not connected to signal ground/earth/cold, just reverse the power input plug connections to that pedal. i've never done any damage to a pedal by the wrong polarity connection (they were protected), but if you have a board with the two types, be very sure not to touch opposing plugs together as this will short circuit the power supply. Just for more difficulty, i spent a long time trying to integrate an old 'analogue and proud' moogerfooger pedal into a board with just one power supply. These are electronically noisy which affected all the other pedals down the power line, so in the end it had to have its own power supply, regardless of the reverse polarity connection. copious apologies Edited October 15, 2013 by TWILITEZONE Link to comment Share on other sites More sharing options...
