Bride of Zen Volume Pot

krikor111 · 12th June 2001, 02:31 PM

I'm in the process of sourcing materials for the Pass Bride of Zen preamp and was wondering if anyone had any recommendations for a volume pot. The plans specify a dual 5k volume control, but finding this creature has been difficult. Also, I have what may be a stupid question: should that be a linear or audio (log) taper pot? The plans don't specify. I assume audio ... but I just want to make sure.

Thanks.

I found a 5k audio pot at MECI for about $1. I use it in my BOZ. Not to shabby. It's tiny, sealed and smooth. That was a few years ago. But who knows, they may still have some.

I don't mean to pick on you, but you (plural) guys really need to put something in your profiles, at least where you are from. That way, we can send you to the closest parts places to you. This is a very international site. Just a friendly suggestion.

If you use a linear pot, you'll get all of your volume in the first quarter-turn. Use a log/audio taper pot, or place a resistor in parallel with a linear pot to make it approximate a log pot.

I started out with an Alps which I thought was pretty good and then a pal brought over his DACT CT-2 which simply destroyed the Black Beauty and so I bought the 10k DACT.

I was trying to sell my BOZ untill I put this attenuator in and now I think I will stick with it.

You can get a good deal on one at http://www.audiocomponents.com and I can not recommend the CT-2 highly enough.

What about solid-state? This is off the site partyjups linked to,

And another Bride of Zen builder did this to his,

I see that one uses the bc547c transistor and the other the bc548. Any thoughts? No pots or switches, is it worth it?
