Oliver,

If you have the 12AT7 tube in the socket and the switch is set for 6H2P tube, will you damage the tube?

Thanks,

Joe

Normaly not, because in this position you have +6,3V at pin 4 and GND at pin 5.
So you would only power up one heater of the double triode.

Hi Oliver, I am building this for the new buffalo dac, do you know what the Ri/v should be for this DAC? On the Lampizator page, he mentions that output resistor for ESS DAC was set to 39R, is that the same as the Ri/v? Or is it the Rin resistor he also mentions?

Thanks.

I think he mentions the R I/V because he spoke from "loading the output by resistor 39 Ohms to pull the output to current mode".

I got my transformer from Antek-Inc, just call them and tell them you want the 9v winding instead of the 6v. It's 5$ extra.

When reading this thread I saw the odd relays in the schematic and I thought I knew those. It happens that I have exactly that type in stock. They are 5 Euro/piece.

Sorry, it appears only the 12V version is still in stock. No 5V versions left.
