Recommended upgrades for Yaqin Tube Buffer ?

[Galgo]

Greetings,

I manage to put my hand on a mint Yaqin Tube Buffer with additional new tubes:
2X Telefunken CV4010
2X Valve electronic CV4010 KQDD/K

I believe the unit is the first edition (CD1!?) with two exposed tubes and point-point wiring inside.

I intend to use it between my computer analog output and the 6CH DIY Class-D amp (Tripath TA2020) in order to play and experiment with "tube" stereo sound (the buffer will only "sit" on the front L/R channels).

The speakers are KEF CODA 70 book-shelfs...

- Are there any recommended modifications for this unit (apart from trying different tubes) ?
Link will be great...

- Any suggestions on automatically controlling On/Off from the PC or the Tripath amp? (anything other than building a separate relay box) ?

How much current does it consume when "idle" - i.e. no input signal? (will it indeed consume full power anyhow?)

Regards,
Gal

Anyone?
Is there already a discussion somewhere on this model?
How is it compared to some DIY boards i.e.:
Arjen Helder Buffer V2

Or if you have other recommendations?

Somewhere i have some comments (in email) & measures on this. It is a fairly simple cathode follower. It is made with relatively cheap parts, so there is room for improvement there.

Apparently I've got the second edition CD2 wit the two 6J1 tubes,
It actually looks pretty well built !
Any suggestions or interesting ideas?
What should I check? (groundings etc..)

how is the sound when u plug this setup ? I too am expecting the amp wanted to know how quality when u hv something like 2ch source->yaqin->tripath->speakers. Do the mids sound mellow and bass is spot on ?
