The Marshall's long awaited set of valves are now fitted and sensibly biassed. I reinstated the missing EL34 screen grid resistors with NOS 1K 5W Welwyns that look like they've always been there. The light in the power switch is nof fixed too. Otherwise, there's not a single bad component in this all original 1978 mode!
V1 position didn't care for the JJ. It hummed like a hive of bees! A lot of tube swapping and was needed finally a Mullard won the job. The owner is very pleased with the restored bass response and gain and no more chance of red plating or blowing HT fuses. The correct 500mA item replaced the rather hefty 2A one! I wish people wouldn't do that!!!
