Ok, so P2P it is. I will come up with a layout, unless someone has one I can look at. Gio, is '3D' wiring same as point to point?

Hi Luis, not sure what 3D wiring is. Point to point allows you to twist AC wires which could have a benefit on reducing unwanted noise.
Take a looks at Bill's point-to-point SE 6T9 tube amplifier build for ideas.
Cheers

Most two stage valve amps are simple enough to go P2P. The brds just make it real easy!

Ееее, not completely chaotic, but not parallel.
Important for me is more hearing, less seeing!

I agree with this guy. I'm not a big fan of super neat wiring. That translates to Mr XTalk to me.

I don't use usually interstage wires, I don't make needless solders, it give me noiseless and no-hummmm pauses and sounding.

Mr.mwhouston and builders of the 6T9 tube amp,

I am new and interested to build the amp for mp3 as well as pc. I am confused about the power supply. I am not sure the 250V-0-250V, 60mA is for two channel or for one single channel?

But for the 6.3V, it is seem for the 2 tube.

Will the 60mA is good enough for 2 channel. I got all the part, as well as transformer of 70mA.

Do hope all can help me.
Thanks

Your transformer with 70 mA is suitable for both channels, and GO AHEAD! /with 3D wiring/ :) 8-)

Yes you can power both channels with this 70mA PS.

The 6T9 tube has been hard to get of late. I have about ten. In that I have one matched pair the others are a mix.

Let me know if you come across some tubes. Spare Time Gizmo was also having problems getting tubes.
