Thank you, I'm still confused because can't see the B+ voltage, the voltage for heater, why the power tx is 650VCT @40DCMA, 5V@2A,6.3A@ 2.0A are you using two separate B+?, are you using 5V@2A? I'm living in Europe so I need tx with a primary of 230VAC.

I'm very interested to buy the pcb+transformer set but I need more guidance before to buy, could you help me please?

I see in the thread that depletion mosfet have to be connected in different way in the pcb or in your pcb is fixed the pcb issue?

I don't need the Maida reg I will use Salas SSHV2 for B+

I have the 0.1 & 0.47uF caps

I need two or four DN2540 depletion mosfet, how much?

Do you have 1 NE2 Neon Bulb, if yes how much for a couple?

Please give all the information you have to complete the kit, thanks in advance.

B+ is 350V. To determine the voltage and current for the heaters, find the tube designation on the schematic and see their respective datasheets. There is only one B+ it is using a center tapped power supply, per the schematic I linked to. I don't know anything about the SSHV2, nor its applicability to this design.

My board never had a layout issue, so there was nothing to fix.

I can add the DN2540 for $1.60 each.

I don't have any neon bulbs.

Neon bulbs are cheap and easy to get (I bought mine at Mouser, there are equivalent distributors in Europe). If it's easier, you could also connect a reverse-biased rectifier (like a 4007 type) between the grid and the cathode of the second tube. It's just there to protect the grid during power on.
