Title: Parts Search: 22mm tape selector knobs for an Onkyo P-304
Post by: OldiesButGoodies on March 01, 2014, 11:22:47 PM
I am missing two of these.  Outer diameter is 22mm,  they connect to a recessed 1/4" shaft and require a set screw.  These do not have to be identical to the ones in the picture,  but ideally should be a flush fit for the 23mm fascia hole (hence asking for 22mm). 

Thanks for any help finding these.

Pepe, does that pre-amp have two tape busses?

Yes.  It is kind of cool,  I should have taken pictures (again) of the interior while I was cleaning it up.

I would wait on a cheap parts unit.  Which you won't.

Just need something to select what the bus is doing until I get the original part.

I've included a link to Parts Express page.  They have a couple around 20 mm that might work.  Look here:  http://www.parts-express.com/cat/knobs/3326 (http://www.parts-express.com/cat/knobs/3326)

This one from Digikey looks very close, a little larger at 23.5 mm:  http://www.digikey.com/product-detail/en/HD-90-4-5/226-4017-ND/305358 (http://www.digikey.com/product-detail/en/HD-90-4-5/226-4017-ND/305358)

This one is a little smaller at 19 mm:  http://www.digikey.com/product-detail/en/HD-75-4-6/226-4030-ND/305353 (http://www.digikey.com/product-detail/en/HD-75-4-6/226-4030-ND/305353)

We both need some parts. I think I talked him into it.

Very helpful - thanks.  Always  forget to check Digi-key for this type of thing.  Parts express is really limited IMO in this area.  Thank you Carl.

That's great news Pepe!  When I saw the description in the Digikey catalog, it looked like they would work.  I'm glad I was able to help!
