I want to change the pot on my amplifier with one from Alps. The
problems is the only Alps pot that matches the dimensions and
resistance has a slotted shaft and my amp has a pot with a flattened
shaft. Is there a way to adapt a slotted shaft so the knob for the
flattened shaft can fit without a problem?

You can drill out the center of the knob to mak it round, then build
up the slotted shaft with epoxy until the knob fits properly.

**If the pot on the OP's amplifier is a standard carbon type, the Alps 'Blue
Velvet' is likely to make a small, but significant, improvement. The lower
noise and laser trimmed matching improves on cheap pots significantly.

Can you email me please?

Drill the original knob and insert a plastic bush salvaged from
another suitable knob ???

If the shafts in question are the same diameter, you can easily mill,
grind, or file a flat onto the slotted shaft.

Assuming the diameter is OK, put a shim into the slot, then (with
the shaft in a vise) file the flat (so it makes a T with the slot).

Depends which Alps model you choose. Just saying "Alps" is no guarantee of a
superlative part. Some of them are IMHO WORSE than Taiwan Alpha who 'second
source' most of the popular Alps parts at a lower price. We had negligible
problems EVER with Taiwan Alpha.

Now, if you want laser trimmed conductive plastic, that's another matter.
