Here's the backside.

Nice, very clean execution. Is this one of your own designs or did you use a schematic you found?

jim · 1st July 2003, 08:45 PM

It's based on a mu-stage design by Doede Douma .
It uses a #30 triode but the ones I have are super-microphonic so I redesigned it for the #76.
The phonostage is Diego Nardi's simple phono amp from Soundpractices.

Very nice... Makes me want to try a tube design

Wardsweb · 1st July 2003, 09:08 PM

Is this the phono stage? I'm looking for a good phono stage to build.

Very pretty. Did the ironmongery come in those nice cases, or did you make them yourself?

Hi,

Hey Jim,

Nice work...if I'd known about your microphonic #30s I'd have recommended some source in Belgium for you...

Bet it sounds great as well?

Hi Wardsweb,

For some inspiration:

Franks' Ultimate Preamp.

Amongst many others that have been posted here in several other threads of course.

Ciao,

Hey there Frank,
is there an ultimate amp to go with the ultimate preamp?
Don't worry, the preamp is in the pipeline, according to my projection I should be getting to it about 18 months from now.
