Help needed to fix my Holy Grail :(

[chrishomfray]

Hi all,

PSU popped on my EHX Holy Grail so decided to mod it to a 2.1mm pin to utilise my pedalboard PSU. Whilst drilling the hole larger to fit new socket the drill caught and ragged the PCB up

I am fairly lucky that it has only ruined one cap (I've jumpered it and get a working reverb, but it sounds a little short with the knob on full), but I cant find any schematics of it anywhere to see what value it is.

It is C31 on the NYC model EC-0060 rev. C.

By any chance can somone please help? I have a gig tomorrow and would love to have this fixed by then.

I heard of a magic RAR file with loads of EHX schematics on but can't find it anywhere...possibly pulled due to copyright issues...?

Hope somone can help.

Cheers,

Chris.

Was it a ceramic cap or was it a silver electrolytic?

Hi,

No idea, it's almost microscopic on the PCB, like this...



...mine is a slightly different layout to this but has the same type of components.

Any ideas dude?

Should be 330nF.

[chrishomfray]

Awesome thanks!

Don't mean to sound untrusting but how did you get to that info...?

Cheers,

Chris.

Also, any idea what it is best to replace it with?

Electrolytic, Ceramic, Film...? Is it power or signal, if power any idea of polarity?

(I don't think it is power as I think that's all up at the top end, but worth checking I spose).

Factory schematic, it's actually the output cap so, film should do ya.

[chrishomfray]

Many thanks dude!

(PM sent btw)

Just to report back, I only had a 0.22uF Tant in my box so thought I'd give that a whirl.

Was a very fiddly job as the contacts are so darn small, but it works ok now.

Thanks a lot for your help buddy!
