Question about Neumann U87 Professional Microphone

Open Question

Where do I find a replacement bass roll-off filter switch for a u87ai?

The switch is made of beige plastic and has a thin, protruding shaft that has broken off. It still functions as a switch, but is difficult to use.

Paper won't feed into slot on Canon P26-DH 111

Could not find anything directly about a Canon P26-DH III calculator but, here are steps I found for a similar model. Please let us know if this does the trick for your situation or not. Thanks & Good Luck.!

Installing a Replacement Roll
Move the power switch in the upper right corner of the calculator to the "Off" position. (or wherever it may be on your model)
Push the wire roll holder back so it protrudes from the back of the calculator. Place the replacement roll on the holder so the paper's end extends from the bottom of the roll.
Cut the paper's end diagonally and insert it into the slot in the back of the calculator.
Move the power switch to the "PRT" position to turn on the calculator.

I have a Sandstrom DAB micro Hi Fi system SHFJMC11 and can not open the door (says door key locked)

just inside the ipod cover you will see a thin black plastic flap that is also the ipod lever, protruding into the door. you need to insert a small thin knife and push this flap back so it clicks flush into it's position. this takes the lock off and you will be able to open the door.

Is there a cabin filter?

Yes its under the plastic bulkhead panel that the windshield wipers protrude from . Fiddly to replace, since have to remove wipers to get cover off. Worth doing though. Pretty scary how much gunk they accumulate.

Dear All, We use a 12-years old Neumann U87Ai for male voiceovers, with no problems. Recently we experience some slight but annoying distortion, especially when recording loud male voice with lots of...

Usually the distortion is from over gain on the preamp or the spl of the actual voice on the diaphragm have him step back a few steps and try again.
Good Luck, Cody J.

First you need to remove the metal cover to expose the brush roll assembly. Push up the plastic cover connected to the foot pedal to expose the motor shaft. Remove the brush roll assembly and simply hook the belt on the motor shaft first then pull back the brush roll and push the brush roll back to the slot. There's a small piece of plastic on the left hand side of the brush roll. This piece would go in after the brush is set in the slot. Finally, replace the metal cover.

Paper "accordians" just as it should be coming out of the printer

The fuser roll has little plastic pickoffs that guide the paper out. When a pickoff wears through the surface of the fuser roller, you get the issues you are having. Almost all the machines out there now have a fuser unit you can buy to replace the whole thing.
