Verified PurchaseThese boards are everything that was advertised. They have brought the beloved JCM2000's back to life and are a fix to problems other than bias drift. Stewart at Valve Tube Guitar Amps was exceptional. He delivered on every aspect of the process and was always accessible to answer questions. This has been a great process and Stewart has been great. I highly recommend these boards if you have a JCM2000.
Hey glad to see we met your expectations and we appreciate the feedback
Verified PurchaseI fitted the board and all went smoothly. The TSL100 is working fine. Thank you - a great job.
Nice to hear it went well and another JCM2000 amp back to making music
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!!
