Hiss / Hum / Noise in my FX-Loop: Error in schematic, or layout?
Hi guys!
I build an amp. Itīs a good 7ender-Marshall-Mix a good blues amp. Iīm very satisfied with its tone. But itīs to noisy. Itīs not an 50Hz heatings hum because this hum was gone after elevating the heatings.
When the master is fully open there is an silent 100Hz hum too, but that is not my primary problem. There is a lot oft hiss when the master is above 40%. I located the hiss round V2. Would someone be so kind and have a look on my schematic, if there is the source of my hiss?
And yes - Iīm a great fan of Merlinīs ideas his page and his book.
