[Heathkit] Part search help needed.

[Kenneth G. Gordon]

I need at least 5 ea 1 meg, audio-taper pot with an attached SPST 
push-pull switch to replace the AF gain pot in the HW/SB transceivers.

I know these are available from places like Mouser, but have not been 
able to figure out how to search for the combination.

These are to enable a "Fast/Slow AGC" function in the HW/SB 
transceivers so the rigs can be used more effectively for digital modes, 
including CW.

I am hoping that someone here can suggest a way to find these.
