The Birth and Evolution of a Phono Stage.

[Mike]

Ooer!... I'd best leave it in there then!

It's for more or less the same phono stage, a WD Phono3, or maybe a homebrew heavily based on it.

The parts are on yesterday's RS order anyway. Thanks for the info, a little bit more learnt!

Cheers,
Mike.

[Mike]

Ha!... 'stuff' has begun to arrive. Rah!!!

Progress soon!....

[Mike]

Pah!

'Stuff' is not arriving fast enough. Waiting is a pain in the @rse!

[Mike]

Maplin doesn't supply the choke any more, but the same one can be found here

What a very nice man to deal with. Thanks for the link Nick!

Cheers,
Mike.

Thats most of the parts now ordered!

I just need the choke and tubes, and I'm away!

Oh!..and a box!

mike,
let me know what tubes your short of, i will donate them, [for the cause]
and anything else your short of, let me know, if i have it, its yours.
anthony...
by the way, you have a message,

[Mike]

You have a PM too!

I'm sorted for the PSU (except for a nice box) but I've only just started looking at the phono stage itself. Can I email the schematic for a bit of advice maybe?

Cheers,
Mike.

yes,thats fine mate...
PS, did you understand my message about your amp???

[Mike]

Assuming you mean the point you made about biasing and matched valves. Yes.

Next time its 'up on blocks' I'll check it out. Theres a complete rewire on the cards in the not too distant future, and the 88's will be due for replacement before too long also.

As for the phono stage, I'll very soon be looking for a trio of ECC83's. To my mind it won't be too important that the tubes are matched to each other, but pretty much essential that each is very closely balanced internally. I'll email the schematics and you can let me know what you think, if thats ok?

Cheers,
Mike.

<*yawn*>...... Here's where I'm at so far.

You can probably tell there's still a little work do. Ahem!

I'm still waiting for a couple of caps and some boxes for it all to live in to turn up, but I've got enough stuff here to make a start. At last!
