This listing is for the Alpha 77 & 77DX Amplifier, Large Knob Inlay (1)It will also fit some BTI Amplifier knobs and Hunter Amplifier knobs.
This inlay measures 1 7/8 inches in diameter.I also have another listing for 2 units which will save a little on the shipping cost per unit.Please see my other listings for knob inlays for many other radio, amplifier and Antenna tuner types.
This inlay has a brushed aluminum finish just like the originals, and they have a plastic film on the face side which you have to remove before you install them.
It is very easy to install. You simply put a drop of contact cement in the middle of the back side of the insert and you can glue it on top of the old one, or you can remove the old scratched up insert with a pick.
To remove the old one you can drill a small hole in the middle of the old insert to remove it with a sharp tool so you do not damage the edges of the inset area.It makes such a difference to replace the scratched or dinged insert as they are a focal point of attention.
