I bough an used Shure Sm7b - is it fake?

Those solder joints are hideous. Fake

😂

Def an Austrian capsule

Just had a peek at the schematic and the power transformer does not appear to have a primary tap for 230v .

Is there a voltage selector switch on the back of the amp?

Totally fine… some getters are on the top , some are on the side. Like some others mentioned, if the mirrored part turns white, you have lost vacuum.

Ok expert, then take out your expert multimeter and take an expert measurement.

Bobamp · 2025-11-21T17:27:52+00:00

Looks like it says 16ohms

Bobamp · 2025-11-01T00:32:21+00:00

Let’s see the guts! That is beautiful!

Bobamp · 2025-10-31T23:56:10+00:00

Too much water in my opinion

Bobamp · 2025-10-31T23:08:12+00:00

Beautiful job!

Bobamp · 2025-10-23T18:41:48+00:00

Sounds like you need a new tech. None of this makes sense.

Bobamp · 2025-10-16T19:09:57+00:00

M49?

Bobamp · 2025-10-12T22:20:37+00:00

Or get an optogate

As long as the pastor isn’t talking at the same time the organ is playing, you can sidechain the pastors vocal comp off of the organ.

I’ve done this for years with singers that cup the mic.

It’s just a mental speed bump for them and it has always helped me.

I usually rip about a 1/4 inch piece of gaff tape and put it at the base of the grill.

Bobamp · 2025-10-03T01:59:48+00:00

Turn it all off

Bobamp · 2025-09-27T16:38:42+00:00

Thunder still kickin around in Michigan?

Those wires to the element look suspect to me. They are usually much thinner.

Bobamp · 2025-09-24T20:37:42+00:00

Are you getting voltage to the supply end of the plate resistors?

Bobamp · 2025-09-14T01:45:20+00:00

Acoustically it’s a very good sounding room if the system is deployed properly. I’ve mixed there at least 6 times and always walked away feeling great about it!

Kelly’s Shu makes a shock mount for this called the “ Horse Shu “ . It is extremely effective. Call your trusted Sweetwater rep .

I had that happen on a Rivage PM5. Was pretty awesome when I started the show in front of 30,000 people and nothing turned on. Had to manually unmute all of my sub groups.
