MK47 PCB tube mic kit - build thread

[Delta Sigma]

I looked at post #100 and didn't see what you were talking about? I was referencing post #1 in this thread and all the missing photos. That's the post I assembled my first Mk47 with and it went off without a hitch.

Did you look at post #100 in this thread? Or post #100 in Chunger's thread that reginator gave you the link directly to?

Okay, I'm a more than a little embarrassed. I saw the post, but hadn't scrolled down far enough to find the build photos and instructions. I've got them now, and created a succinct PDF and stored it locally, just to be on the safe side. Man, Chunger is a DIY ninja!! Amazing work! Thank you. I've got what I need now.

Am I the last man on earth building an MK47 ?

This thread is dead quiet !

No, you're not the last one. But I just might be... LOL

 

[reginator]

Awesome! Post a pic of your mic when you finish the build.

I finally ended up building it, and love this mic. I'd like to build another one but really hard to find as these kits are sold out for a long time. I bought mine around here on blackmacket's page.

I understand. I've been hanging onto my last kit for years... The time has come for me to finally get it done. Sometime before the end of this year, I'll have everything I need to make it happen.

It seems there is a mismatch in my microphone:

Switching polar patterns creates a very loud popping noise.

Cardiod works as expected (front is loud and clear, read is muffled and low volume). But in omni mode the front sounds bass shy (papery) and the back sounds loud and clear.

Is there a schematic of the MK47 somewhere? All the images from Max are gone, unfortunately...

Thanks!

For the build thread, check the one from Chunger. Lot of very detailed pictures of the build from page 5 or 6.

The MK47 still rocks! I would love to build a few more with different capsules.

Thanks, but I am looking to fix a specific problem with a mic I built 10+ years ago here. I need the schematic and maybe some advice what might be at fault. Ideally what the voltages should be a which points and how to measure them (high impedance part).

Check at Dan's version D-47. Same design with two 4408A tubes.

I found the schematic (on reverb.com ).

What could be going on in my mic? A mismatch between the two sides of the capsule? A bad relais connection? Or stray capacitance/resistance (I had scrubbed the PCBs) squeaky clean...

Again, the front side sounds fine in cardiod setting, but bass shy and with amplitude lowered in omni (whereas the back side sounds fine in omni and is muted as it should be in cardiod).

Does any one have a BOM for the MK-47 I want to make sure I get the correct parts that are missing.
