MK-U47

Andreas Grosser´s fabolous & very reliable FET replacement is called VF14ER (Ersatz = german for replacement)

The VF14r is my own take on a (tube-based) VF14 replacement.
The Bv.08c transformer is a wound to the original Bv.-08-00 A specifications and will work perfectly well with a original VF14(M) tube.
The MK47 directly resembles the u47 circuit.
I have been working on the amplifier for more than two years and i´m quite excited about the outcome.

That sounds great!

So your VF14r is an FET VF14 replacement as well?

 

[ioaudio]

Oh, no, it´s tube-based (thanks for your hint - edited).

 

[Skylar]

You're manufacturing tubes!? Or is it an existing tube?
This is getting more interesting by the minute.

Wow, great video, work of aft, thanks for posting...

You're manufacturing tubes!?

no, i´m not that crazy 

 

[Skylar]

So, is it a tube that's obtainable?
I would assume so.
And what did you do to it to make it operate with the VF14's heater voltage?

 

[ioaudio]

Like others have done with schematics, i will not reveal the tube type used. At least not at this point.

 

[Skylar]

Cool, well I can't wait to see what you've done!

Awsome!

The mk7 mics I made sound absolutely stunning, so im ver excited about this!

Any news on the EQ or microphone?

Oh tempting... finish my mk7s.... or sell them and make a mk47.....


Is there going to be a huge difference?

 

[living sounds]

I'd like a set if it fits the same chinese mic body as the MK7.

Ummmm.... So did the Pultec project just disapear? Or am I missing something.

 

[Bluzzi]

Just saw this. Count me in for 2. Please don't let this project die! It sounds like you've done a lot of work on it.

All the posts on it are gone now. It's way spooky. Where did it go? It was damn sexy

You can count me in for a pair of MK47s....
