I like to order but don't you think that usd 32 Is too high
I've got pcb's for the lightspeed from dvb-projekt . Very good quality. But in this case. If you find it too expensive. Best would be to go p2p. It is quite a simple circuit.

Kind regards,
Bas

We will lock temporarily the thread. It is ''Under investigation''.

EDIT: The thread is back in operation after the disputed buzzword and other references have been removed or substituted both from thread's title, text, and PCBs. Please refer any technical question only to the group buy manager.

Hi to all,

now that all discussions are made, i have opened a new thread,
who everyone could discuss the Tube-I-zator SRPP Stage schematic.
Feel free to post!

Best regards,
dvb-projekt

I like it very much. This posting i made because there are already a lot of srpp tube buffers to buy.

Here is a little excel application where you can calculate the output impedance of several tubes in a srpp stage.

Hi Koifarm,

thanks for your post. I think everyone know this, because thats nothing new.
The most advantage of the Tube-I-zator board is that you are not fixed to any 9-Pin tube,
because of the Heater-Switch. As i know the community, they would like to test the
circuit with different tubes in their projects.

The link to the excel application is pretty cool. Perhaps you could also post it to the....

Ups, i see you already made it. Thanks.
