Attenuator/balance control for my Preamplififer

Guijs · 2nd November 2005, 04:51 PM

Hello people!

I need a stepped volume attenuator and a source switch for my tube preamplifier. What do you guys recommend, one volume control for each chanel or a balance control like the Dact CT3? Do you guys think that the Dact products worth the money? It is possible to build a equal quality control?

Ok,

I'll use one MONO attenuator for each channel.

The Dact use series resistors, so the audio pass trough all the resistors. I found this one here :http://www.goldpt.com/prices.html

were the resistors are in parallel so the audio pass trough only 2 resistors.

Does anyone know this ladder type attenuator?
would be better than the Dacts?

Michal Percy has real good stepped attentuator kits. High quality stuff.

Build a mono pair, or stereo. Either way you certainly don't need a balance control.
