Hi where in UK can I buy replacement capacitor for my 1968 DR103

type 50 + 50 microfarads mine is 500volt rated altho I see on some circuit diagrams rating is 450 volts

I can readily get 40 + 40 mF would this make much difference, I'm a bass player ( someone has to be )

These look fine: ... 1c1fdd84d4

They've been good to deal with for me too.

I'd think, especially as a bass player, you'd rather go with more capacitance than less. :wink:

Since those capacitors are produced with a +/- 20% tolerance, there may not be a whole lot of real world difference.

I forgot to add something about capacitors in my last post?
I have known a Filter capacitor to hold 290 volts in it and thats been powered off over 2 days and still held this dangerous voltage in it.
If you decide to use the resistor to discharge it then make sure you insulate the pins at the top with some insulation tape to make sure you don't expose your fingers to the legs when discharging them.
One other point, I have known a Filter capacitor to store a heavy charge after being switched off for almost 1 week, a mate gave me a jvc dvd recorder to repair and I took the psu out and put it on my knee (forgetting to discharge the filter capacitor) and when I picked it up to do a test I got a right shock off it.
So be careful, if you follow my tips then you will be safe.
One final point, I don't think that a capacitor that's storing a high charge can kill you, but give you a nasty shock, I may be wrong if they are lethal or not but I don't think so, either way be careful when messing with HV Caps.
