Hi, I though I would have a go at replacing my cheap & cheerful V/pot with a better quality one. i choose one of the Chinses small 21 step resistor Howver it works & sounds very good but i can only go 3 clicks before it is TOOOO loud.
Sop how to solve, do i
Change the pot for say a 20k or 250k one. Or put output resistors on the output RCA's
Cheers

What value was the original, continually variable pot?
Details of the the stepped pot you bought would be helpful.
Indeed.
Asking a question containing vague info doesn't get intelligent answers.
"I have a car.... it won't start, what's wrong with it?"
What does V/pot stands for?
Is that volume potentiometer?
They come in various resistances, and more importantly, as linear or logaritmic.
You need to match both.
You likely did not...
Easy fix, put your V/pot back.
Is it wired backwards? Would that explain it??
If it's a linear pot it needs to be logarithmic for a volume control. You can try a 'law faking resistor' if it's linear, to make it behave more like logarithmic.

Not always.
There's plenty of audio components that use a linear control for volume.
Hmmmm, that's very interesting I have never heard of that, it opens up quite a few more options. I didn't use a linear pot and a faking resistor when I made my passive volume control because it was a shunt type, and I didn't know what the interactions would do with two resistors and a pot.
Hi guys, thanks for your quick replies.
Original pot, no idea, no markings on it. it came from a E/bay made up board.

The pot i replaced it with is one of these

If the pot was wired the wrong way around, it would decrease the vol, not increase.

They need to know what resistance pot you ordered...10K? 50K? 250K? And if that's the resistance you received, I imagine. The pot on the preamp board in the picture says 50K on it.
How far did the original volume pot had to be turned open to get the same volume as after three clicks with the new one (with source and power amp being the same)?
If the original pot was an Alps 16 (like it says in your first link) than it's strange that it didn't have any markings on it. But if it was an Alps, how did you know that the new pot would be of better quality than the Alps 16?

Hi, Again thanks for the replies, sorry it's a bit like pulling teeth.
Original pot received on board was not an Alps pot, as we know the Chinese rarely put the correct/original parts on the board. The old pot cannot be re-used as it was destroyed in removal operation. Original pot went to about 1 'o' clock for loud vol.
The 21 step pot i used for replacement was 100K.
