Re: CJ LP70S
The 6550s pin array is different to the EL34s. They are NOT direct interchangeable. The difference in not only the plate bias current. Is the pin array too. Look for the pin out for each tube. You will see the difference. the third grid on the 6550 is connected to the cathode, pin no. 8 and the thir...

Re: Oh! For the love of tubes!
As I always keep saying: let your ears decide...and still, no matter what, the sound of the tubes are the final winner for my ears. Yes, there are some SS well crafted and I do like their sound, I must get accustomed to the way that they sing. The bass usually is much better on SS, I admit this. But...

The other four fuses are in the main DC power supplies. On the MF2200 and MF2300, these are located ...

Re: Bias lights not working on LP70S
Well, the trick is to have the four LEDs into their position, wiggling a little bit the PCB and then their screws. If you have unsteady PCB, this means that the secured screws are loose and need a retighten all of them. NEVER USE FORCE TO PUT THE LEDS BACK INTO THEIR POSITION.

Re: Bias lights not working on LP70S
Hola smodtactical, You don't see the LEDs into their hole because they are not in the right position. The first thing that you have to do is to take the whole PCB (print circuit board) apart again. Then straiten again the LED pins back again with much care. Before you put the screws back that secure...

Phono 1 is for MC and MM , phono 2 is for MC and MM too. PHONO 1 factory adjusted for both MM a d MC cartridges. The 53dB 47.5Kohms~63dB ...

Re: Oh! For the love of tubes!
The problem is that this effect is only for one person seating in the sweet spot. If you move a little bit, the effect is lost. The tone and harmonic texture do not change.
What it is truly funny, is to see the face of the listener. What funny face expression they get...truly funny.

Well, I have some in stock. I was lucky to get the Cstock just at the beginning. The price was very low if I do the comparison. Also bought some Genalex Gold Lion 6922 too. This Genalex is not a bad sounding tube, I do know that there are other brands offering better sound. OTOH I am very happy with...

Hola Chicos, Last night I had the left channel with a truly rare, peculiar, unsteady behavior of one power KT'120. It was located at the front of the amp. The LED bias started to blinking on one tube, and then I did try to adjust it with no luck...then I saw another tube just behind it, with the top...

Thanks Admin, You are right with this!!! All I know is that. On the other hand, you can configure the pre for AC input 120 V. or 240V. But I forgot the AC cable and the connectors. Yes, you need a special IEC 240V AC plug and cable. Just thinking loud, this could be a nice DIY project or you might t...

Great advice Admin! I love the KT-120s in my system. I did try out recently an octet of KT88s, and ending again with the KT-120s. I found much better bass control and the stage too. The overall image with the right size of the musical instruments and voices, the KT-120s Tung-Sol are the clear winner...

I just got for service an amplifier with a hum on only one channel. This amp came to my hands from another workshop. Thanks to God, it was not canibaliczed but the did try to find from where this unwanted hum came from. I was lucky. I don't know the reason why, but the problem was an induction hum. ...
