Guitar Chat - New Valves and Biasing my Marshall JCM 2000 TSL 122 - Part 2

Replacing the valves on my beloved amp has been a bit of a long process; see part 1. In part 2, I am fitting a Dr Tube stable bias board to correct some manufacturing problems. SAFETY WARNING - Obviously don't open high voltage equipment if you're going to end up electrocuting yourself (or breaking it of course). The valves are from Watford Valves. https://www.watfordvalves.com/ The bias kt was from Valve Tube Guitar Amps. https://valvetubeguitaramps.com/produ...
