Amplifier Ins & Outs

Gratuitous picture of tangled mass of guitar cables
Replacing the power amp tubes in the Marshall Amp got it working, but then the volume started spontaneously changing. That coupled with the resistor that fell out (!) and copious advice that the tubes should be correctly biased led John to haul the amp downtown to the Portland Custom Shop on East Morrison to have an experienced tech look it over. They had a substantial backlog of work, so it sat down there for a couple of weeks, and then a family matter came up and the guy is going to out of town for a couple of weeks, so this afternoon we drove down and picked up the amp and drug it over to Wire Audio underneath the entrance to the Hawthorne bridge.

Next time we take a trip down there, let's do it in the morning. We managed to avoid the Morrison bridge fiasco, but not having clear directions to where we are going (no, Google directions are NOT clear), and not bothering to look at a map (I know where I am going) led to having to back track several times and sitting at traffic lights for extended periods. Took us two hours round trip. I'm tired.
