Quality PCB’s. Well made, strong, with good print & nice sized solder pads. I appreciate a good solder pad. You don’t realize how important they are til you encounter cheap boards with little rings that lift if you accidentally apply to much heat or stay on the pad too long. This board is very versatile. I purchased a couple of these 9pin boards. One being exactly like the one pictured & a ver2. Ver2 being the newest layout. Gives you a lot of options on how you want to do a circuit. The board is outstanding for the price. Very cool. I built off the schematic in the supplied pic & it is truly a fantastic sounding circuit & tube. Now I’m trying a 5670 preamp build with my other board. This 9 pin PCB is great.
