UA Apollo preamp knob

[MiamiBoy]

Can anyone recognize what this is?
Im trying to find it on Mouser, but I'm not having any luck in the searches.

It's the Preamp click knob, with infinity turns. Looks identical to the Monitor knob.

Universal Audio Apollo 8p
199 or 661 stamp on it

It looks like what you need is the encoder. The "knob" is the round plastic thing that you use to turn the encoder. Do you still have that part? I'm not that up on the different qualities that distinguish one encoder from another, so maybe someone else will chime in here with that info. Have you asked UA if they will sell you the parts?

Thank you for participating, Ike.
I still have the knob, yes. It's fine.
The encoder broke and I wasn't succesful gluing it back on, since it's metal and there's no stump left at the base.

I haven't asked UA, no. I don't even wanna bother.
I figured this was a standard component like a potentiometer that could be found on Mouser. Maybe i'm mistaken.
Hopefully someone can shed some light on this. Thanks

The encoder

Even the designator next to it says "ENC1".

Odds are the other one that's still in one piece could be used to count how many steps per revolution you're looking for..? Looks like you want one that also includes a switch. Pretty standard stuff otherwise.

Thank you. I found some parts on Mouser, but not an identical one.
I just started a ticket with UA, let's see how they reply.

If led array match impulse/turn this is a 18 step ?
No ref on the back if you desolder it ?

 

[Khron]

but not an identical one.

And you figured that out how, exactly?

If led array match impulse/turn this is a 18 step ?

Why would that be the case?

Aren't they called 360 degree "endless rotation" ?
Someone replaced theirs on an Apollo Twin https://fb.watch/waX7BHkfSY/

I wonder if it is the same as inside the Apollo twin? mine seems to have two steps for every LED - so a rotary encoder capable of something like 56 different output options.

I think MOST rotary encoders are infinite turns, at least the ones I have run into. There were some in a solid state Fender amp from the 90's I just worked on.
