Re: Which is the BEST step attenuator

195.99.125.202

Hi there,

All things being the same (which they never are) I'd not recommend any Series Attenuator. The difference between Series and Ladder is not quite as large as that of Pot vs. Attenuator, but close.

I personally recommend Military/Telecom Surplus Switches, preferably using teflon pieces for making the switches but allways with sild silver "coin" Contacts. The Switch should be a 4-Deck unit.

Then simply wire your favourite Resistors in, directly. I personally use a specific type of industrial metalfilm which sound exceptionally good, better than Holco and Co, though not up with Vishay.

The result is an attenuator better than any commercial part known to me.

Later Thorsten
