Verified PurchaseA big thanks to Stewart and the team. After a bit of a learning curve on my behalf. I have assembled my TSL 100 with new pcb, set the Bias, no drift. And now can enjoy my amp at full power after it sat for 20 long years. I thought the day would never come. Cheers from New Zealand!!
Great to see another Marshall JCM 2000 resurected from the deal and back alive with our ROS-2000 board
