Super Nifty Phonograph Preamplifier

My first boards from PCBWAY is for a Phonograph Preamplifier Circuit for use with 78rpm (Shellack) records, Cylinder Records and Edison Diamond Disc Records. Circuit has variable roll-off and turn-over frequencies as well as adjustable rumble and notch filters controlled either by onboard Atmega chip, external Arduino or analog potentiometers and rotary switches (depending on how board is loaded/wired). Circuit boards I received from PCBWAY are PERFECT! Silkscreen is clean and crisp. Edge cuts are clean. As this was my first order I opted to go the least expensive route and allowed PCBWAY to add their number to the board for easier processing. Their number is done in extremely small font and was placed in area that will be under a SOIC chip, so will not be visible when my project is complete. Very pleased with this. Standard snail-mail shipping and and I still received finished boards in less than 2 weeks after ordering. Uploading & verifying of Gerber files was quick and easy. All holes are clean and my components fit perfectly. Overall a great experience and IMHO an unbeatable value. I highly recommend PCBWAY to anyone looking for a PCB manufacturer.
