Have a great and very dusty birthday, Dusty!

They are different tubes. The only thing they have in common is the pin out and the fact they are both double triodes. Buy an AVO. The manual is quite clear about the different settings for the two tubes.

Excellent. Quirkily it has a tube output stage and tube rectifier. It was also fitted with an Audio Note paper in oil capacitor, which went leaky. Sent a message to Audio Note, the accepted that this was a flaw with that design, and sent me a pair of film in oil capacitors free of charge. That problem was sorted too. So really there was a series of problems with the design, but now everything works flawlessly, and sounds great.

Almost had exactly the same amps. Except I had an LS3, and exactly that power amp - the D125. Mind you because the tubes are fan cooled, I made sure there was enough space above it to dissipate the heat from a whole lot of 6550's. Sold them some years ago; they hold their value very well.

Someone either fast reverse or fast forward. RIP Johnny Nash. Incidentally if you do a US patent search for van halen, he has umpteen granted patents on all things guitar; hum bucker pickups, tremolo effects, guitar design etc etc.

Bloody hell. van Halen. RIP

The Tent seems to have a problem with the SPDIF output that stops a DAC from recognizing it. I have not got round to finding out why. I could I suppose just use the analog outputs the same way that I do with the Dynalo. Might be worth trying. I actually got it for fee from a guy who I did some audio consultancy for - he was strapped for cash and paid me in audio gear (The Tent, a couple of LFD amps, and ESL57's). The Tent did not work; the design was mainly surface mount, and one of the transistors associated with the clock had blown. That had taken out the astonishingly fussy CDM-pro spinner. I replaced the transistor with a discrete one on thin wire legs to the SM pads. Then Tent sent me a new CDM-pro mech FOC - which in spite of antistatic handling failed to work. I sent it back to Guido Tent, and he replaced it free with another one and sent it back; it has worked since. The manual for the Philips CDM-pro says that power rails and clock have to appear in a particular order, or death and destruction will happen. How they let these things out of the factory with such arcane requirements is bewildering.

For me it is that each headphone is associated with a different listening system. The T2 clone is fed from an Audio Sythesis DAC and a Meridian CD transport. The BH is fed from a phono stage, and a Thorens TD 150/SME3009/Shure V15IV with Jico stylus. And the Dynalo from a Tent Labs CD player. So it is what source I want to use, rather than a go-to pair of phones.

Sweet!

In the bedroom: Stax Lambda originals bought late 80's fed by KG T2 clone. An absolutely awesome headphone! In the dining room: Stax ST007 fed by original design of BH In the other bedroom: DT990 and K701 fed by original Dynalo with Borbely discrete regulators. I also have a pair of Koss PRO4AA, bought for nostalgia sake, because they were the first headphone type I bought in the early 70's. Truly lousy SQ and a real head crusher weight. And Koss ESP9, with a bias source and amp that is the biggest POS ever, but sounds good. Both pairs of Koss started life with their fluid filled pads that were supposed to seal the things to your head, that were no longer fluid filled and rock hard. Replaced by soft pads that seal well enough. The other thing that needed replacing on both Koss's was the foam cup filling, which had gone like tar. Hell of a mess to clean out.

What is the sack for? Wotcha going to build?

Fitz you're the second person I've heard of (recently) who have had failure of Fluke multimeter input jacks.

Happy birthday, squared!

Happy birthday!

That is awful Jose. My heartfelt condolences. Fuck cancer!

Happy birthday tall fella! Hope you are having a spectacular one...

Just catching up with this thread. About ten years ago we had a Renault something, and it had a quirk. If you half closed the door the central locking would fire. So in January I parked in a remote car park to go for a run in cross country shoes through the mud and slush snow. Got back to the car soaked in sweat, tossed the keys on the drivers seat and as I moved to the boot (truck) to put dry clothes on, the door half closed - clunk. Keys and phone inside. Me outside in freezing temperatures, soaking wet, and it is getting towards dark. Fortunately there was an elderly couple in this carpark in the back of beyond. Their children had bought a mobile phone for them for Christmas, which they had not used. They offered to let me use it to phone for recovery from the company we paid for (RCA). "What is the postcode" "No idea - it is a remote car park" "Can't help you caller if you don't have a post code" "Please understand - if you don't help me I will die from hypothermia!" "OK - I'll walk to Little Whittenham and your guy can meet me there" "What will be the post code caller" "Look - Little Whittenham is about ten houses - he won't have a problem finding me!!" To cut a long story short, the recovery guy extracted the keys and I got home unscathed. Craig

I thought the kookaburra impersonation was impressive too!

I saw the title of this thread and read "mistresses" instead of "mattresses" That'll be an interesting thread I thought...

Diamond based semiconductors have been worked on for at least a decade. Note on the site there are no specifications for such devices. There are still massive hurdles to be overcome in fabricating semiconductor devices on silicon. And - a real irritation - how many women do you see on their team?

OMG I can't unsee that....
