Tube-I-zator Professional PCB

[dvb projekt]

In the process of populating the 3.1 TubeI zator board.
Would appreciate some close up pictures of the board from various angles.
Have to adapt the parts to something that are available locally.
thank you

Hi,

sorry for the late reply, but i was in holiday. 😉

Look HERE in my flickr Album. There are some pictures you want.

Best,
Oliver

I am unable to source the heater switch and intend to solder the bridge. If i am using 6n2p, is this the correct way to solder? See attached picture.

That´s the correct way.

Hello Oliver.
BZX55/C12 SUBSTITUE

Can i use other alternative 12 V zener substitute such as 1N4742A ZENER DIODE 1W 12V ?

 

[kp93300]

Or this one which is cheaper ?
Is the zener tolerance critical ?

1N5242B - ZENER DIODE, 500mW, 12V, DO-35 from Multicomp with 5 % tolerance

Hi,

i must ask Salas, because it is his circuit. 😉

Stay tuned...

Here ist Salas answer:

Hi Oliver

Its a protection part. Not precision critical. 1N5242B should do as a substitute.

Hello everyone,
Can I use 12bz7 tube in tube I-zator in 3.1?
(so I did not change the original body parts)
Thanks.

Hi,

if you want to try the 12BZ7, go ahead.
The double heater current (see attached data) is no problem for the heater circuit. Maybe you will need a bigger heatsink for the LD1085. 😉

Best regards and happy Easter,
Oliver

Hello Oliver,
Thank you very much for the answer and the information.
Have a nice day.

Hi Oliver,
I see on your blog that you still have the Tube-I-zator PCB; I am interested to purchase.

 

[shattered_dream]

Me too....

Hi,

i have only a few Tube-I-zator boards left. If you would like to order, please PM me your paypal address.

Best,
Oliver

 

[shattered_dream]

One for me... Send u pm

Hi Oliver,

I'm using your tube-i-zator for IV of PCM 1704, the sound is very good. Recently I want to try R2R DAC. Can tube-i-zator work as tube buffer? I think I can use it as buffer by removing IV resistors, am I right?

Cheers
Eric

Hmmmm......

Anybody has still one in spare

Hello Oliver,
I'm finally (after 3 years!) getting around to building my Tube-i-zators, and I want to use them with a voltage-out DAC chip in a Cambridge Audio DVD99. I'll add the cap, but what value should I use for RI/V? Lukas' instructions suggest 250K, but his circuit is a little different than yours. I'll be using 6H6P. Thanks David

@ All

If you would like to use an DAC with V-out, omit the I/V resistor.

OK will do - thanks Oliver
