Where can I buy thoose resistors ?

I dont know I never bought them.

Thank you Saulius . I sent a Email yesterday to them asking where to buy.

Just in case anybody is interested I have one to give

It's Alive!

The V3.1 Tubeizator is running...!

I used the Rhopoint resistors for both Rk and Ri/v. The sound is very good in the early stages. I will post more comments after 100 hours.

On the V2 Tubeizator, I used the "naked" resistors for both Rk and Ri/v. While the Vishay's are very good, for this application I much prefer the Rhopoint.

Thanks for a very good upgrade board Oliver.

I sent an email to ask for the resistors to Rhuepoint. They did not answer.

I am finally getting around to putting the Tubeizator into a case I did a search but couldn't find the answer to my question which is;

The transformer I have has a 2A 9v secondary that runs the heater supply, does the heater supply need the whole 2A? I was wondering if I could run the Twisted Pear Placid HD PSU from the 9V secondary as well?

Witch tubes are you using?

The 12AX7 needs 300mA heater current for each tube, so 600mA for both.

I would left a threshold ~30% to the maximum of your secondarys 9V/2A. So you have ~800mA left for the Placid HD PSU.

Excellent, I will give it a try thanks

Well it didn't work, for me anyway. Using the one secondary to run both the heater supply & the BIII PSU ended up injecting substantial noise into the system, Maybe it was the way I had it grounded, after playing with the ground setup I went back to a second transformer and all was well.

I was toying with getting a new version of the Tube-I-zator but they are sold out

Do you think it would be possible to easily implement the soft start onto my V2.0 board? Every time the tubes flash at start up I cringe.

I've finished my DAC with tube-i-zator v3.1 and Ian's FIFO kit. However, the heatsink of IRF840 is quite hot (around 50-60 degree). I can't touch it over 1 sec. Is there anything wrong?

Input is AC150V and B+ output is DC150V. All components are brought from Mouser in accordance to BOM v3.1

Thanks!

Sorry I cannot answer your question but do you have a build thread for the DAC looks interesting.

Hi DQ828,

Thanks for your concerns!

I think two 6N2P cannot consume most of current from SSHV so IRF840 is very hot. I'd like to increase R21 to 100 or 120R, so output current can decrease to 16/20mA. It may be better than before.

With the Euro set to fall even further I assume the Tube-i-zator is pretty much discontinued?

 

[DQ828]

I think the seller does not get enough customers and may have lost interest. I would buy on if there was one

 

[Kang Kel]

How sad......Seems like I arrived a few years too late.

At the price they were I can't believe the sales dropped off.

A lot of the SRPP output stages seem to be discontinued now. Hopefully something comes up on the 2nd hand market. Has to be a few unpopulated PCB's lying around somewhere.

Really want the Tube-i-zator though and not willing to settle for anything less.
