Volume Adjustment

Not an engineer. Wonder if there is a simple answer to why volume setting 53 on my MA-252 seems so much louder than 52? Speakers are Sf Olympics llls. 

It’s certainly not 1 decibel ?  Is it logarithmic or something I won’t understand ?

Are there amps that have just 1 decibel increases? 

When I listen at setting 52 and want the sound just a little bit louder, setting 53 seems too loud ?

Answers and thoughts appreciated. Thank you.

That’s strange 1 click would make that much difference. What about 51 to 52, is it a similar increase in volume?

From your description it seems that there is something amiss with the volume control. There should not be such a big difference with a 1 decibel change!

something is wrong. measure with an spl meter to document the change, then give McIntosh the facts.

you can buy an inexpensive one (with a bottom hole for a tripod), it's good to have one

The pot may have oxidized. DeOxit spray can be used, but be careful to keep it away from other components. Let it dry thoroughly before turning power on again.

If this doesn't work, it may be possible to disassemble the pot and clean inside it.

That is probably a job for your tech.
