I'm in need of a couple of knobs (even one will be great) for a Pioneer A-91D amplifier from 1988/89. The knobs were used on other Pioneer units of the same era. They look like this: https://i.pinimg.com/originals/5f/0a...6a34d4728f.jpg
That's the amp at the bottom of the pile and the knobs are the 'wedge' shaped ones at the bottom left hand side.
Thanks, please PM me.
