Default Bought my parts but missed the 1500uf 6.3v cap's will these be an alternative?

as the title says really forgot to buy the 6.3v 1500uf caps

I have used bits of an old circuit board and there are a pair of 10v 4700uf caps. obviously the voltage rating is fine but will the capacitance be too big for the transformer.

I have an edcor XPWR059

cheers, Reidy-

Which amp is this for? Looks like one of the cathode resistor bypass caps. Should work fine as long as they physically fit on the PCB in that location.

C10 and C20? They are bypass caps for R10 and R20. Using a bigger cap here will not have any negative impact and the ones you have will work.

The only consideration is that they ought to be reasonable quality, low impedance types so that they are an effective bypass across the audio range. The parts spec'ed by George are low impedance types from Nichicon (Mouser) and Panasonic (Digikey). What you have are probably low cost, general purpose types. They will work but a better cap will sound better.

Ok, well I needed to get a few more parts so I bought a couple of 2200uf elna caps @ 16v from world-designs.co.uk

hopefully they should suffice, will upload a picture of the built amp when its done (in the next few days hopefully.

just waiting on the coupling caps ( I bought soniq sax .47uf @ 630v) then it'll be ready to rock.
