Leak Stereo 20 vintage tube amp repair/upgrade, EL84. Surprise issues!!

Here's a video on assessing, upgrading and repairing a 1958 HH Scott Leak Stereo 20 tube amplifier made in Britain. See Part 2 for hooking it up to a vintage Leak Point One Stereo preamp. Replaced broken fuse holder. Replaced junky electrolytic caps with metal foil and ceramic ones. Bypassed power supply caps with more capacitance. Replaced Radio Shack junk resistors with low noise ones. Re-installed missing 8-pin octal socket. Discovered this is the 230VAC British version of the amp, but it has American 115VAC outlets on the back!! WHAT??? Please subscribe for more!!!
