100R trimpots - best brand for audio
 
These are to be used on a discrete buffer for nulling DC offset, any suggestions as to which brands are reliable?

It's hard to find bad parts these days. Anything that will fit will do the job.

I always use enclosed type to keep the dust out.

I would rather say "It's hard to find good parts in these days"

Bourns 3296W, three wire, in line, vertical 25T adjust.

Don't use the Chinese knockoffs, often they do not engage with the adusting screw.

If you have spare money, use any of these

I changed to use (10R) 1260 on my Erno's 320 phono preamp and it produces more details VS the stock supply which is already a good one from Japan. Adjusting the zero offset is a piece of cake since the voltage does not go up and down with small turn. The price could be a concern because it is over $30 each but you can also consider a cheaper alternative such as 1280 if your PCB allows.

Bourns cermet 10 turn are well made, reliable and reasonably priced.

Excellent, thanks! Might try the Bourns as they seem good value for money.

Thank you for this advice. Also a wide range of their other devices about

Sheesh, looks like it is possible to spend some big bucks on small components!

While we're on that topic, what is an audio grade DPDT switch to use for toggling between two inputs?
