Astatic 575m6

Oh, it’s buried in here somewhere. It’s all about changing the 270k resistor.

I tried clipping the resistor first, and got great reports. Some here said that could cause the transistor to overheat, so I swapped in a 1.5M resistor. Some go whole-hog and put a tiny trimmer in.

I also changed out the switch, since the stock one goes scratchy in a matter of days.

I probably have less than $40 in the mic all said and done. They pop up for 29.99 on eBay all the time.
10-4 on that switch. Mine is acting flaky. Think you could dig up that thread or information concerning?

Pic of switch. Not terribly fun to replace, but doable...sourced mine on eBay per the above link.
Yup! That thing is small. My switch is failing, have to watch the readout or needle to see if it's working. Agrivating, pos. I could send whole thing back but no packaging.

Where you get the switch? Is I worth a "switch"?

I bought a pair from eBay, I believe from the link Nomad posted, or at least from the same seller.

Mine was scratchy from the factory and quickly grew worse. Replacement has held up fine. No symptoms yet.

So...for the price I’d say very worth it.
 
:whistle: I know the feeling....what did you buy? :sneaky:

Just mobile mics today...another D104M6B, (2)SRA-198s, (2) Turner RoadKings, a RD104 (I’ve never owned one) and a Workman something-or-other power mic (looks like one I had a long time ago that worked well).

And add to that...a bunch of mic cords and connectors to fix all the others I have laying around..hahaha.

So...7 mics and a bunch of parts. Lol.
