Tube-I-zator Professional PCB

[TJF]

Is there any experience in using balanced Tube-I-zator (ESS9038Pro) directly with Hypex-Amps like the big NC2K (low input imp). I saw that the 12AX7 has a high output imp about 30k. Any other arrangement or recommendation instead of 12AX7?

I found this ...

- for 6922 -> 637 Ohm
- for 6SL7 -> 12,7k

Any source to 6N2P?

 

[TJF]

- for 6SN7 -> output imp. ~ 3,95 kOhm
Gain 19,5 dB, Rk= 590 Ohm, V=200V, I=0,4mA

Right?

I have some Polish unitra telpod MPHP1 capacitors that I was thinking of trying as the Output capacitors but they are only rated at 160V, is this likely to be an issue 🙂

With B+ of 150V you have 10V headroom. I don´t think it´s critical.

Excellent thank you
