History
In May 2016, Ian O decided to get #16 working. He had heard from Matt F that Clint B had plugged it in and it produced no voltage. Ian disassembled it and tested the capacitors and resistors, finding them all within spec. He also started converting to use a modern grounded power cord (IEC 60320 C14 inlet/C13 cord) using a power inlet module taken from an unusable piece of equipment on the free shelf. He got most of the way through this conversion before Jack S brought in #18, which was already working, on May 31. The plan became to use #18 and keep #16 for parts. On the same day, he brought in his tube tester (B&K 700) to help Ian diagnose #16. All of the tubes it had tests for (i.e. not the 0A2s or the 1619s) tested good. Later, during Meet & Geek, Robb L's tube tester was used to test the same tubes with similar results.
