Default Frank's Ulitimate Tube Preamp.

This thread is for a new preamp by our fellow forum member Frank aka. Mr.Tube.

I hope there will be a good exchange of ideas and arrive with a design we could build.

The floor is all yours Frank.

Jam

P.S. The preamp is going to be called Franken Tube for obvious reasons.

Default PREAMP.

Hi,

Let's just say that at this point we'll give it our best shot?

Shall we say that for now I see it as an open invitation to all to input their thoughts on active preamps...

Everyone is welcome I would think?

So, to get constructive...we are going to need some good volume control, a good low Zo PSU and the ability to drive any awkward load, balanced or not.

So far, we can manage that...

Cheers,

Default MIJN KLOMPJES...

Hi,

Does anyone object against a preamp that has no gain, would be an active buffer preceded by a stepped volcontrol?

The PSU would be a series regulated supply, dual mono.

Let me know what you think.

Cheers,

/Je zus.

Hi fedgroov

For me with todays sources...more than a pot and a buffer...is overkill ...

Frank,

Sounds good to me but what if someone wants a little bit of gain say 6db.

To burn it off somewhere else? Don't know about that but I figure that if you need gain from a line stage we could complicate things.

For the record, I don't need any preamp with gain other than my phono pre, if however, I can help anyone with a preamp we could make one with or without gain.
I feel that the idea about gain is wrong in that what you need is drive capability, not voltage gain as such.

Still, I'm listening to hear your needs,

Frank,

You might be right. Let it be a buffer then.

Let Franken Tube begin..........

Regards,

Jam
