It looks like you are after the AKG GB 40 guitarbug

Hello,
I would be inclined check your +48v phantom power supply to make sure the correct voltage is coming out and to check your cable. Failing that, if you have changed the tube once I'd be inclined to contact AKG Directly via email to find a service center or get furthur advice.

AKG sells the replacement screen and tube assembly direct from AKG Acoustics, U.S.

They are expensive, $80.00 each.

Take a look at my tip on replacing dodgy cable/plug on headphones, you might find the solution there.

DX 2517 and DX 2527-
Symptom:Buzzing or motorboating sound in either the transmit or receive.
Problem: TR602 is oscillating
Cure: Replace C602 with a .01uF cap {Cap is located in the power supply board}.
RG 66,99,DX2517 Replace Q54 2SB754 60watt 7A with a higher power 2SB817 100 Watt 12A. Derating of this component will cool operation, provide better voltage stability,decrease wobble, allow voltage increase to 14.5 volts comfortably. (replace 10 volt caps in this section of the radio to a minimum of 16 volts before increasing supply voltage to this level)and provide faster swing rise time, Replace Q37 2SA473 to a 2SA1012-0 or ECG153 this will improve the clarity and volume of the modulation and it will also run a lot cooler.

Maybe you could find a local music store that repairs equipment to replace the grill. Sometimes you can find parts on websites like Ebay.

Sorry that the parts list is in German, but at least you can look at the visual, see how they are put together and order the parts. Although this microphone has been discontinued, parts should still be available from AKG.
