Hi Mike - Storage really - freeing up a bit of space on the main Hard Drive to get the operating speed back .

That's a terrible shame Dave .
Seems to have been a very bad winter for bad news about talented people .

There's loads on EBay Mike - OK they're mostly in the States, but postage would be OK if you bought a few .

Thanks Bob . I actually think Oscar Peterson was spectacular, but I know exactly what you mean by his ability to shift gears and make terribly difficult playing sound natural and unstrained . One of the best things I've seen was this piece 'Con Alma' from an old 'Jazz 625' programme on the BBC that ...

I was just browsing Thomas Mayer's site, and came across this low-cost indirectly-heated valve that he was excited about , as an alternative to 300B's : http://vinylsavor.blogspot.de/2011/01/tube-of-month-6cb5a.html It immediately occured to me that it would be nice way of driving an 845 or GM70 cle...

It's not as dramatic here but has been snowing lightly for about an hour and a half. Quite a rare sight round these parts .
It ain't half cold ( mum ) out on the back porch sawing bits of wood though . I had to put on my 'North Face' winter hat .

But if a choke fails to act like a choke, in the woods, and nobody sees it fail to act like a choke, did it .... no sorry you are correct, Nick

Please tell me you're not testing that A2 amplifier while drunk at the edge of a swimming pool

Aha
Looks like Nil Point from all the judges except Nottingham . Cheers.
I'll keep you posted . Looks like a day for doing a bit more on the horn , so to speak .

Anyone got any snow yet ? I've had the car loaded up with camera gear, was hoping to go out to Snowdonia and get either some sunny frosty conditions, or a bit of snow coming down - but it's neither. Local advice tells me it's grey with high cloud and the frost has melted . Just going to nip out here...

I was thinking that Neil , thanks - most likely USB (1) .

I was thinking the same thing myself.
I've been more than happy with CCS follwed by 2x OD3 on the PS of my phono amp for several years ; with a by-pass of about 0.1uF and 300R to kill some white noise and aid transparency.

Remember ye the parable of the tortoise and the hare ...

Steady, if not spectacular , progress .
The big ( mouth ) end doesn't half eat up sticks of 20x20 !

Hefty !
What kind of volts can you feed it, Dave ?
