A&H fader AI8117 verses ALPS RSA0N11S9A0K

I'm trying to replace a broken mono slider on my A&H wz3 16.2 and Mouser sells the ALPS RSA0N11S9A0K which seems to be identicle to the AH AI8117. I could order the AH model number through dealers like Full Compass or Spectrum but, at the risk of sounding too frugal, I really prefer to purchase from Mouser as I may decide to replace many and could save a bundle through them.

Connecting a recording light in control room

Not real sure if this is the right place to post this question so redirect me if needed please (maybe I should be in the construction forum?). I'm slowly building my studio (see thread under "Small Studio Build Journey") and during some construction lately I wanted to plan for a "recording" light in the main entry area.

24V PSU for vintage German modules

Hi,

I've been trying to get around to racking a few modules for years now and still haven't. Some Filtek and TAB stuff. At the moment I'd be happy with simply getting a PSU and testing them out to see if I even like them before forking out the cash for professional racking. So, I just need a PSU and a few XLR cables basically, and I'm researching this now. What do you guys use?

How different are LCD Drivers? (non-audio related)

I have to repair a Grade Select board from a fuel dispenser unit, and it has a proprietary chip in it which I can't get replacements of for obvious reasons. I can however find similar chips which have the same number of pins, form factor, and are also LCD drivers. What are the chances that these drivers will be interchangeable with the ones I'm looking to replace?

PT2399 chip alternative

Hello all,

So I've built a little angel chorus pedal using the pt2399 chip and i get a white noise that is a little too obvious. I took the chip out and the pedal is dead silent. I goggled and it turns out the pt2399 chips have a reputation for this noise. So... My question, is there an alternative quieter chip i can use?

Thanks

Watkins Copicat grounding

Hello everyone,

I just bought a Copicat ic300 and it has a 2 core mains wire which means it's not grounded. I've had a look around the web but can't find instruction on how to ground it. Can anyone help? is it just as simple as replacing the 2 core to 3 core and connecting the ground to the case? or is there more to it (ie, inputs need grounding)?

Thanks in advance.
