The Mic

[analag]

It's alive and this might be one of my very best. China K47 dual. How is that even possible. I'll caĺl it luck, everything came together I guess?

Active loaded triode 5703?
I really like your veroboard approach. Got motivated to try it for mics, i only used it for stomp or 'secondary' circuits in previous built. Thank you for inspiration Analag.

Active load 5702WB in this case. When you're ready I will send you the schematic.

Here is a freestyle I did after overcoming a notorius hum the mic exhibited at first turn on. I had to lift the grid resistor to make it behave. This is a dirty track with dirty lyrics and cracking voice, lol. The mic is super quiet. This is $27 aliexress K47 and active loaded 5702WB and I'm hitting it hard to see what she can do. I may remove this later. Zero processing just a pinch of reverb.

Sounds exactly right.
(reggae voice?)

Do you have a link where you got the k47 capsule?

Always ready for schemo. Few component in this one.
Studying the one with lnd150 and 67 output transfo you shared some times ago. Very intrigued by it.

Off Topic:
Analag i like your voice and style!
Do you have tracks of yours published somewhere?

By 'terminals' you mean the component leads?

Nothing with myself. I keep meaning to do it but...
The solidstate I finished yesterday is no slouch either. That one has a single side K47. Very realistic sounding and I notice how it captures the background in a vivid way. I used an organic capacitor (47uF) to bypass the source, feedback is handled by a 10pF between the drain and gate. The addition of the source follower fixes a number of issues including crappy lo end and low output level. I'm about to start my final two mics, solid state and tube respectively. The tube mic will be active loaded with the U67 type transformer.

If you decide to do it you'll have at least a listener for sure.

I feel like I could knock this one out tonight, but I'm taking a break. Tomorrow is another day. I'm going with a JAN 6206 this time. I like trying different pencil tubes. They say the life span is short but I have replacement tubes to last me for years upon years.

One moar. Goodnight.
