Hi,

Another nice Russky tube... if you can get it.

In theory that should not be a problem...what kind of circuit are you looking at?

Cheers,;)

6H30
 
Hi,

First of all,let's take a look at the datasheets:

6H30

The tube has the same pinout as the ECC88/6DJ8/6922.

So for use as an output stage in a DAC you will see that is very well suited,it takes higher plate voltage than the 6922 and will have lower output impedance too.

Circuitdiagrams using this type will be extremely rare since the tube itself is so hard to come by.

However you can use existing diagrams using the 6922 family of tubes and adapt these to take the 6H30.

Have a look at it while I try to unearth some schematics for you to try.

Cheers,;)

DAC.

And I assume you want to replace the output stage with one based on this 6H30 ?

This is not for the beginning DIY though...if feel up to it let me know.:cool:

tube
 
hi frank,
i have no problem in building if to follow according to a circuit.

have look at the link that u have provided..thorsten circuit looks promising..guess i will follow his circuit...

so all i need is to build thorsten circuit and plug in a 6H30 tube in it..will there be any problem? ofcourse power supply is a different story..thorsten circuit uses one tube perchannel

>can i use my preamp 5687 circuit but uses 6h30 tube as dac tube output?

>thank u.

:o There seems to be a small problem with the volume control connections...

Provided it is a volume control.

What is this circuit for,anyway?

If it was meant for a DAC than it seems incomplete to me.

Cheers,;)
