Looking for 2 knobs, difficult to find a good source to get them

[edusub]

Hello everybody,

I'm looking for two knobs to replace the original ones in an old Marantz 1997 PM66se amp. They are 50x27mm and 38x27mm. Shaft is knurled "D" shape 6mm diameter.
After researching a lot in different webs and, obviously, in all the sellers from eBay.com, I didn't succeed to find exactly two knobs with different diameter but same desing, colour (preferably in black, if not will paint them properly) and height.
I found many in 50mm and 38mm but always different in shape, design, height and colour.

Has anyone around here any clue or address where to find a supplier of spare parts with a wider catalogue of knobs that could suite my need?
Ideally it would be best to find a replacement of the original knobs of the Marantz but think this would be a hard task, then I addresed my search to producers of generic parts.

Knobs could be in solid stainless steel, steel with plastic inset or also only in plastic. Also height could vary between 25 and 30mm but what is imperative is having the sme desing and height.

Thanks everybody that could help and regards.

Eduardo:

I don't have a third party supplier suggestion for you, but have you considered contacting Marantz? Even if they don't have any replacement stock, they may be willing to tell you the source for their knobs.

That couldn't hurt.

But be aware that for most OEMs, knobs are custom pieces, made to spec, not off the shelf catalog items.
