You can imagine that I was excited to take my newly arrived TA-30 head to my weekly jam yesterday. But after an hour or so, problems arrived:
1- When changing channels (with or without the footswitch) the sound shut up completely, not even a hum ! I had to toggle between the 3 steps of the wattage switch (for exemple, from 40 W to 30 W to 15 W and back to 40 W) a few times before the sound came back. But then, changing channels again and the same thing happened : no sound.
2- It seems that there is almost no difference between the 3 wattage settings. I can not hear a distinct volume increase as there was with the TA-15 (wich I had before and made an exchange for the TA-30).
3- When these problems arrived, I also heard a "click" repeating with regularity in the reverb.
Then, after a while, everything return back to normal, except for the difference in volume between the different wattage settings.
This morning, I've tried it again at home and everything seems normal (except again for what I sense like a lack of difference in the volume).
Last remark : you can see the four EL84 tubes at the back of the amp. From left to right, they are at position V7, V8, V9 and V10. In 15W mode, it uses V8 and V9 and all four of them in 30W and 40W. The V7, V8 and V9 have a red glow and the V10 does not. Could it be that it does not work ? Could it be the cause of all this ?
I'm gonna call the store tomorrow but I wish someone here could give me some infos before. Thanks in advance.
And oh ! by the way, while it worked it sounded marvelously good ! I'll report back when this thing gets fixed.
