Finishing the chassis
Lots more soldering.
This time we need to attach each of the jump leads to the right components. This normally involves finding the right wire (not always that easy, given that some of them run under the board, and come up out of the same hole as another wire), and then attaching it to a very small pin on the tube sockets.
So far so good. All the joints look pretty clean, and some elementary tests with a multimeter seem to suggest that the right points of the circuit are wired up to their counterparts.
There's definitely a lot going on in there, but it's amazing how neat and tidy it all looks.
The instructions neglected to tell me what to do with the black wire from the output transformer, but I managed to work out that it needed to be grounded to the speaker output jack by looking at the circuit diagram. The old magic is still there!
