Hi Brian
I have some 2a3s and 45s, but I'd like to run this with the 01-A. Thoriated tungsten filaments, more gain, etc.
The filaments need 5 V. 0.5 A, and B+ is 135.

And the 71A: same filament supply; max B+ is 180, but 135 should be ok

How much would you charge on top of an assembled amp, to set it up for them?

Default Tram 2 ,best i ever had

Like to tell a little about my Tram 2 pre---the sound is the best i have had in my system---it had the feeling that you are in the music--this i have not heard before---the review by enjoy music is just right--so i am very happy by the result---
i have make some hum and microfonic damper-----2 big iron tube--one over each 45 tube--
and a wire from the iron to shield on the input---this had removed all hum--and less crackling on start---les microfonic--
the iron tube is 10cm ---15cm high---5mm thick--

Hi
What are the differences, both technical and sonic, from the original Tram W.O.T.?

I've not heard the original Tram WOT but I do know that WOT means "With Output Transformer", the mkII does not have an OPT. The mkII is a totally new preamp, sharing nothing with the WOT. The diyhifisupply site has details and link to the review of the mkII.

Sounds like a good solution as the 45s don't get particularly hot. The Tram mkII does sound really great doesn't it!

Hello Clivetjm
The tram 2 have a sound ,that could be hard to understand--i have before that-a Aikido-a pass lab x02---conrad johnson act 2--but the tram2 is just more what music is about--

Yes, I've read all that

"original Tram WOT but I do know that WOT means "With Output Transformer", the mkII does not have an OPT. The mkII is a totally new preamp, sharing nothing with the WOT"

So they are both relatively unique in being WOT. How do you know it is *totally new?

They are not both WOT. The mkI has OPTs, the mkII does not. The mkI used 5687 whereas the mkII uses 2A3 / 45, it uses the DIYHS heater modules, Active Bias module, Ultimate Volume Control Module, Universal all Film Capacitor Power Supply.....I don't believe these modules existed when the mkI was around. Like I said, totally new.

Hej Carlo
i dont now how to upload picture---i could perhaps send it on mail to you---
the iron tube is just a water tube - i have drilled some holes in---for cooling--
the reason why i have make that---is-- that the tram 2 make hum---worse when i hold my hand over it--the iron tube removed it totally--but remember the wire to input ground
i am not finished with the iron tube---have to paint it black--

Bjarne
