Experimenting with Chipamp.com Mono PCBs

Tripmaster · 12th February 2009, 02:04 PM

Hi there

I have purchased several Chipamp PCBs and plan to experiment with a different selection of components to the ones Brian supplies with his kits.

I really like sound of my current Chipamp dual mono but I find some of the higher frequency range can occasionally sound harsh.

Can anyone suggest a nice selection capacitors-boutique resistors they have found work well together?

The amps will be powered by either Pedja’s discrete power supply or an LM338 regulated supply.

Thanks for your help

Richard

I've got the best ones available anywhere and at a very reasonable price (now that I've had a conscience bypass)!

Try carbon film or carbon composition resistors, and make sure that your heat-sinks are not too flimsy.

I haven't tried different capacitors but I really like the sound of my chipamp.com monoblocks and so don't feel the urge to experiment.

I used Panasonic TS caps in the PSU, Panasonic FC's for all other electrolytics and Vishay-Roederstein MKP1837's for all the 0.1uF caps. Some people rave about the MKP1837's...

I've also read (can't recall where) that caps in a chip amp have a larger infuence on the sonic end result than resistors.

How about using carbon film instead of metal film resistors? Some think carbon = less harshness.

I’ve been expecting you!

What - to hold your soldering iron?
