    Thanks for looking!! You are right. I am using lead free, yes. I've reflowed some rough looking ones and the one you pointed out. No change, yet. I did measure all the pin-to-ground voltages to the IC's now. Pictured here. Does that look normal? ziUPGHp

    Häßliches Entlein :D Ganz sicher nicht der schönste,sondern der häßlichste Treter,muß aber auch mal sein :cursing: , Das kommt dabei rum,wenn man huddelt und sich nicht die nötige Zeit nimmt und mal auf die schnelle ein Gehäuse zusammen dengeln will :D

    The solder joint on the very left of the picture, when the board is flipped it's close to the DC jack, looks quite cold. There are some other solder joints which look a bit rough. You are using lead-free solder right?

    Update, please find some detailed photos here. To me, all wiring and component population looks as it should. If anyone has a tip based these symptoms (it turns on and passes amplified sound, but no modulation) and photos, I'd be glad. Only thing I…

    Hello, Thanks for the reply, It's always hard to find an intermittent fault, the amp was fine yesterday. I desoldered and tested the components, they seem fine. I'll buy a new tube and parts, easier to replace them anyway

    Hi, it seems that one of the anodes (plates) of the 6N6P double triode output tube is glowing red, which means the current through that half of the tube is far too high. Tubes are more robust than transistors regarding that but after a while (might be 5…

    Hey Axel, from the top your overall build looks clean and nice, but possibly there is a cold solder joint hidden somewhere. It would help to see the circuit board from the bottom. Could you post a high-resolution picture of it? Matthias

    Hello, I built my G3 Blues over a year ago and it worked without problems. Lately the amp cuts out after 10-20 mins. The V3 grid is glowing not just the heater. After I switch it off for 2 mins the amp is fine and the measurements are ok. I checked for…
