SSHV-Shunt Module

My last thoughts to optimize the Tube-I-zator goes to the B+ High Voltage lines.
To get the maximum flexibility, i have made splitting points in the lines.
The splitting of the anode psu lines brings upgrades possibilities.

You could use e.g. a tube rectifier with C-R-C filter instead of the onboard andoe psu or
switch to a regulated shunt psu, witch in my mind brings the greater sound quality upgrade.

With the experiences from Salas low voltage shunt on my DAC project in mind,
i have made an upgrade module for the Tube-I-zator based on his HV shunt circuit design.

Here it is

The specifications are:

- 2mm pcb
- Immersion Gold
- green soldermask on both side
- 70m copper weight
- Board size 46mm x 133mm

Next batch is scheduled to 6th February

The price is:

HV Shunt regulator Module: $ 14

Worldwide shipping: $ 9
Europe shipping: $ 5
paypal fee: 3,9%

Shipping insurance on buyers request!

A donation of $3 USD to diyAudio will be done for every pcb sold.




And the result....

... an absolute H O L O G R A P H I C playback!
The sound image is so perfect, better than any experiences before.

Also the possibility to reproduce great dynamic jumps is better than ever.

As i played my favorite dynamic test track "Fanfare for the common man"
from the FIM Super Sounds! III CD, a XRCD24 recording,
it blow me out of my chair!

I think that was the last peace to heaven...

A big to Salas for this wonderful circuit.

In the attached file you find the BOM.


If you add the SSHV to the Tube-I-zator with the recommended 56R shunt current setting,
you must change the 1K C-R-C resistor on the Tube-I-zator to a 2W type!
