the amp looks great, excellent job.

Just imagine what it would sound like with the correct cartridge loading mark?

What is the cartridge loading now and is it relatively easy to change?
(I'm not suggesting we change it)

I've done a bit more listening today to Simon's phonostage (now that is thoroughly warmed up. I was particularly struck by how good it is during crescendo; there is absolutely no blurring. or confusion, of notes competing for your attention. The dynamic range is huge too - music suddenly swells in a very dramatic manner and bass is rock solid. I must say, I like it a lot!

it's relatively easy to change I just need to remove the main boards flip them over and put a different SMT resistor between the input and gnd pads. I don't have the resistors like...

I've been busy, already built a closer matched and better specced V2 version.
Just finished last night. So I'm waiting for the input bias to settle, which lovers of foo will be delighted to hear takes up to a week as the electrolytic capacitors form/settle/burn in. proving that all caps don't form in seconds rather than over a period of time. (They do of course have next to bugger all running into them)
here's the temporary cart loading arrangement. I'll shift this onto the back panel via a plug-in of some sort.

Mark has been building little houses to shield my transistors from the draught.
I had a head to head with a Tom Evans Groove Anniversary yesterday. Both were set up for the specified loading of my cart. To be frank the TE got it's ass handed to it. Better bass, more coherent top to bottom, better resolution and more dynamic contrast from my own ickle diy stage.
Does anyone fancy the challenge?

Simon, that phono stage (with buffer output?) would retail for at least couple of grand I reckon, once components were selected and a more fancy box customised. I suspect the kit costs aren't that cheap either

It would probably retail for circa 5K.
The little transistor house looks cool .

Nice one, Simon... I'll bring my Croft and Ortofon ST-80SE round, after the holidays (end of August) and we can have a play. You need a decent hard-wired, PCB-free, valve MM phono stage/MC SUT combination to give those tranny-boy active MC upstarts a royal rogering!!
