Hi Guys! I have a question. Lately one of the current meters started to show higher values than usual. On the start the value is the same on both meters (as below). After around 2 minutes the value reises up to It is connected with the tubes. That's for sure. But what can this mean?

Hey baronbeehive, don't be sorry for to show my work. The position of my pot dose have nothing to do with the volume regulation. When I had problems with hum I dicided to dismantle the pot and use the tantalum 2W resistors. And it stayed like this. I am controling the volume digitaly in the...

The "silver" extension was done by me. To do that I have to order the corner elements to be done by CNC processing from aluminium bar 10x40 mm. Having the corner elements I have assembled the extension frame usin perforated steel plates and prefabricated aluminium corner elements. Then painted...

Maxx good to hear that you like the 6C8G. I have bought few pairs of them. I did not have an opportinity to test to many types of the driver stage tubes. So hearing from you that I just have done one of the best choices make me feel good :). Very simiral are the 7193 KenRad with adapter. They...

It is not a grill. I have installed material similar to the one used for the speaker screens from outside. It is similar solution metioned in the other instruction but done without opening the headphones. To mask the edge of the material I have glued decorative string around.  After the problem...

HEK's amaze with the sound qualities in every aspect. Especially after some minor mods. They have the same huge soundstage as HD800 but deeper and better filled with instruments. I have folowed some of the mods from these instructions but a little different way And I have replaced crappy 50...

baronbeehive great that you have your amp back to live! 

Yes I have changed them. But in my case and also Sonic Trance the resistors and diodes in the PSU section get burnt and our meters did not move on.

Guys I am also very interested in the outcome of your findings. Did you manage to discuss the optimal values of the resistors? Is there any mathematical or good practice rule connecting the values of the cathode and anode resistors?

baronbeehive did you change the PSU transistors or you are using the stock ones?

I have got at last 2 pairs from him. But it looks like I had been lucky. PayPal helped .

Finnaly arrived. The guy just forgot to send them after my payment :). He has done it two months later after the dispute on the PayPal had been opened. It can happend but why he did not respond to my messages?  Now the 7193 are runing and it looks like this:   Compared to 6C8G they are in...

Mytek 192 has an ADAT input :). I just find it out and thought it may be interesting to RN 3 owners.    S/PDIF Optical Input (Toslink) – Consumer digital input that accepts up to 96KHz. Can also accept professional ADAT signal up to 96KHz.

Yes, you alredy know that I had been prejudiced to NOS tubes. And it seams I had correct feelings. Buying a NOS tubes is a lottery . But you know what. It is worth to risk!!.  I will tray to replace the out of order tubes (it shall be no problem). And for now I have ednded up with three pairs of...

It looks like all the strange problems are connected with the tubes. One RCA tube is totaly dead. One National Union has only one rod glowing and one Ken-Rad does not show any visiual signs of failure but after some time starts poping, ckracling. I have another pair of National Union and they...
