Hi guys!
I am new inhere, and have just finish my first tube amp. I started with the Triton kit, and I am amazed by the sound, and not least how quiet it runs without a signal. No hum or whining.
I have some question about voltage. My Amp Runs 6L6 (10W) Tubes and is supplied with 240V AC mains voltage.

According to the Triton voltage map I measure on V1: 22v on pin 6 and 142V on pin 8 against chassis. I also measure 19V on pin 6 and 128V on pin 8. Measurements on V2 show pin 3 350V pin 4 292V and pin 8 24V. Is such a big deviation ok. If this is wrong, does anyone have any suggestions?

Could this be caused in what I see is a difference between the layout drawing and the manual ver.1.23 page 43 regarding cabling of the Bias switch? I wounder if one is right, then the other has to be wrong. I have used the one on te layot. Please let me know.

I will mention that all the measurements in the startup procedure in the manual were measured correct before the tubes were installed 5V AC, &, 3V AC and 400V DC. As mentioned earlier, the amplifier runs just fine. Great sound and no noise. Maybe a little loss of volume?

Happy to here from one of you experienced guys

The posted voltages are for 6V6 tubes so yours will be off a bit. It will drop the votage down a bit.
We dont have 6L6 voltages published. That os somethng we need to do. If you like it, it is good.

As for the bais switch, I think they both accomplish the same thing. They change the power cathode resistance. Confirm you are running in 6L6 mode. (bias resistors in parallel).

Thanks for your reply Stephen! Seems like a good explanation. I have followed your Builder's Guide carefully step by step and I most have forgot for a moment that I was building the 10W version. I now feel that I have passed the first grade in the tube amp builders school, and look forward to the next level.

Hopefully you’ll find one of our amplifiers that you want to try next
