yes please :cool:
It's possible version 1 was a development board that was never put into production.Quote:

what the difference is and if ones better than another is over my head.
im getting a bit confused with regards to replacing these capacitors,nf,pf or uf??
i need 2 of these,

and 3 of these,

The top two are 220pF (0.22nF). The bottom one is 10nF. :)
Thanks Alan , I had a good read up on cap markings last night and sussed it in the end:)
ive been using a denon ha-500 headamp so the poor little lentek hasn't had a look in,today i recapped it though which is a start :)
does anyone know if the wilmas are bipolar?

The Wimas are none polarised.
Best type of capacitor to stick in there is either polystyrene or polypropylene dielectric.
However you only need a low voltage rating of capacitor, the problem will be finding small ones as most of this type of capacitor have large voltage ratings and will be correspondingly large in size.
Good luck :)
PS may be best to try it as is and see what the improvement is so far.
Cheers Alan,yep that’s the plan for next weekend
