A friend of mine is interested, Ali.
He will likely email you soon, on your 2019 email.

They're not useless. I am assuming this is a DIY project, with 12A's ( ! )
Get some sort of circuit set up, with a B+, anode load, cathode resistor and bias. Get some voltage readings and compare...

The Gm is just being quoted in Microsieverts rather than millisieverts, so the value is 1000 times larger.
Aka Micromhos, see for example the RCA sheet for the 112A ( = 12A )...

The key for the 103 is primary winding inductance.
Hopefully it's more than 2H , otherwise the bass will suffer.

Ok, I'll buy it. I would like to hear it again, and I have a friend who will buy it off me in due course.
I am just off to a Christmas do, will contact you either late tonight or tomorrow re....

It pains me that this unit isn't selling. I've only heard 2 DAC's that really excited me, this one, heard about 15 years ago in Audio Note's room at the Radisson, and Nick's Longdog Audio one.
The...

Picked up my LP's from the post office today, Grant. All safe & sound.
Condition on these are just great. The Big Joe Williams one in particular - rare to see a 1969 original in near-mint condition...

I think it'll just be the two, please :
137 - Big Joe Williams 'Hand me down my old walking stick"
271 : Robert Wilkins "Before the reverence"

I saw that - but I already have it - on Delmark. Great LP, one of the great blues recordings.

Cripes - I only just noticed this !
Big Joe Williams 'Hand me down..' from '69 would definitely be of interest.
Can I have a look through till Sunday ? - only I have an audio meet at the house on...

Can't do 100 quickly, but here's a stab at a few -
Top 5 - (probably )
2001
Tokyo Story
Chinatown
Pat Barrett and Billy the Kid
The man who fell to Earth

Next 25 -
The Conversation (...

The VPI one is no cheaper than Nick's, it doesn't look as slick. I'm not sure how they compare technically but I know a fair bit about the LDA one as a few years ago I supplied Nick with an abandoned...

It used to be easy until very recently.
Yuichi's site was : http://www.geocities.jp/arai401204/
I was able to access it again recently on the Internet Archive ( Wayback machine ) and saved many of...

No, that's very restricted vertically, a Smith Horn. Not convinced about those.
The Yuichi is more or less like the TAD bi-radials or the Vitavox ones as used now on the Vox Olympian.

Definitely worth trying. I would loan you the pair I made for a short while, if you were closer than West Sussex ( I'm in N.Wales ! ).
I am still trying to get an upper-bass horn that does justice...

To which posting was this a response ?

Depends if the voltage rating and power rating are enough for your power supply.
ps. A 2W resistor will get very hot if it's used at more than 1W, and may not last long.
Metal films are usually the...

Have you advertised them on DIY Audio or AA Tube DIY sections ? Seems like you need to find the right person. I wish I had an immediate use for them, as they are rather special.

I have a Dynavector XX-1L from a few years back which was re-tipped by Expert Stylus and run about 40 or 50 hours before I swapped over to an XX-2/II then back to my Denons (!)

Micky - did you get a PM or email from me ?
Need to send you a couple of pictures.

I was at Euro Triode Fest in 2005 and heard about 25 phono stages in the shoot-out. At the end I think there were 4 LCR phonos and Allen Wright's differential ( balanced ) RC-based phono in the final...

Ah, good. I'll take a pic of it for you this evening and dig out an LP box to put it in for posting.

I'm not familiar with any Thorens platters - there is a 2mm to 2.5mm wide 45 degree chamfer around the edge of the underside. This may have been a modification by myself to account for the 401...

Funnily enough I have one - had completely forgotten about it. It's black, 5mm thick and it pretty good condition. I have just dusted it off. it was stored on top of a bookcase but on top of...
