Aphex 107 mods

and yes it is now far more precise, dynamic, with the same gain. Has anybody
the same experience ?

Yes. But why does this surprise you?

Build a solid state network on a blank tube base and replace the tube (?)
Just kidding..... but not exactly impractical. Probably reduce the noise.

Try this simple thing :
- open your 107
- get the actual value of the potentiometers beside the tube, VR104 and
VR204
(if you have to go back)
- turn the potentiometers on the left
That's all...
It doesn't change the level of the noise, but it gives more accurate high
ends.
Tanks to Scott who gave me the clue in an old post.
Good luck.

I understand *get the actual value...* but what do I do with the value?

I understand *turn the pots on the left* but look, I happen to have one of
these things, and I didn't know it could actually be used for anything, and if
I open this thing up and find the pots on the left, do I turn them until it
sounds good? Is that it? Is it possible there's some practical limit to the
turning? Or should I just crank away until cows come home?
Also, what on earth do you use it for? Is it anygood on anything? I'd like to
know, because I was ready to chuck mine.

Nothing, but if you want to rollback your mods it will be useful.

Oh my english... It's not the potentiometers on the left, but the VR104 and
VR204 that you have to crank contrary clockwise

Yes, but I think these pots dose the tubessence effect, and now I am sure
the less tubessence effect the better the 107 is.

On saturday i recorded a concert in the local music school with my modified
107. The wind instruments were really fine.
I was able to compare with earlier similar recordings in the same hall,
before the 107 mods. All is more dynamic and the space is more realistic.
The noise of the 107 isn't a problem for me because I often record public
classical concerts and there are other noises...

Jean-Marie,
Can you explain what this "mod" is?
Thank you,
Paolo

This means that you are switching tubes off. So, couldn't Aphex produce
a cheaper solid-state preamp/converter?
I suspect you could improve the tube sound by replacing the original
tubes with better ones.

Those should be the bias pots. If you turn them fully counter-clockwise,
there is no more bias, and the tube can't work at all.

Not entirely. The tube is still in there a bit.
And yes, they could produce a cheaper solid state preamp, but people wouldn't
buy it because it doesn't have tubes. The Symetrix 302 is basically the same
front end without that ghastly tube stage, but you'll notice that the Aphex
sells a lot more units than the (better sounding and cheaper) Symetrix.

Maybe, but again they run the tube in a very strange way....

Gee.... then I was sort of correct in saying that you could build a solid state
network on a blank tube base and loose the tooob all together. This is
much much easier. ;-) Just turn it off !!!
