Gyraf GSSL 50kohm Pots
« on: June 12, 2018, 03:11:13 PM »
HI there,
Sorry if this is a stupid question but I'm getting nowhere on the Farnell website.  We just received two cheap looking Bourns 50KOHM pots but they work and we're ready to wrap the build up.  Is there much to gain from upgrading to nicer Vishays and is there any difference in this scenario between cermet and conductive plastic models?

I am specifically looking at improving the "feel" of the pots.

When selecting pots, you can use 47K just as well as 50K. European pots tend to be in 10, 22 and 47 values whereas elsewhere they tend to be 10, 25 and 50 values. As they are all usually only specified to 20% they are pretty much interchangeable.

yep, agree, if it works, don't fix it

No audio passes those pots anyway

Yeh we were looking at 47k pots as well but pretty thin on the ground, we finally found some very nice Vishay Sfernice P11S's that are military grade and good for 2 million cycles, only 10 quid a pop as well, not happy with the sh*tty Bourns as the shafts are plastic.

The feel of pots is a bit subjective and doesn't necessarily  correlate with price.  So just get a few and try.

Generally stick with carbon and conductive plastic models for front panel controls.

The Vishay Sfernice P11's arrived, they work and feel incredible, sturdy and very serious.

There's really no need for supa-dupa uberexpensive pots in those positions. They are just voltage dividers and don't pass audio. For a nice feel you can check out Alpha (Taiwan) pots. They are cheap and have a nice feel to them.

I always thought about putting stepped pots in my GSSL. Any recommendations?

How precise those steps are? For mastering grade you'll probably need switches anyway. It's interesting to know if anybody has actually measured the stepped pot resistance at each step.
If you're fine with 12 positions you can use cheap Lorlin switches that should turn out not too much more expensive than a stepped pot.
