Well, hello everyone.. My first post here after observing for a few days.
I've just got the parts to build the the Meta 42 amp. I'm following the schematics only so I'd not be using the PCB from tangent.
The problems comes with C1 & R2 of the setup. Since it's stated that using a 0.1uF cap with a 100K resistor would have "significant attenuation and phase distortion", I've got myself some 0.22uF Metalized Polypropylene Capacitors (Evox PMR's; The best I can get in Singapore) and 1M, 1% resistors for C1 & R2.
I'm not too sure about how to read the graphs from the Micro-cap 7 graphs but I assume the lower frequency to flat out on the graphs is better?
So it'd be fine if I used C1 as 0.22uF & R2 as 1 megaohms? Or should I raise C1 to 0.44uF?
It's alright to change their values at the moment since I've at least 1 week before the Farnell delivers to the shop I've placed the order for my EL2001CN's (I hate having to order; The shop is earning 20% from me).
