California Dreamer Tuneup

My friend Charles is moving out of town so he dropped off his California Dreamer for a tune-up.His basic complaints were baggy grille cloth, too much noise in the reverb return circuit, backwards bass control. Here's the amp with the front valence off.
Here's the view from the back. Charles got some nice reverb cables that dress well on their own.
Here's the chasssis out of the box. Note the close proximity and less-than-90-degree angle between the output transformer and the reverb transformer. This was on the checklist of things to adjust.
Here's a basic gut shot. Notice the heater pair going from the reverb return to the PI - dressed right over the reverb tranny leads. And those leads themselves are too long and can be tightened up. These heaters will be rewired.
The fixed circuit. Notice how the new heater leads from the reverb return to the PI are dressed way back. The reverb transformer leads have been shortened and dressed away from anything else.
The adjusted trannies. Now the cores are farther away and at right angles.
Completed repairs. Valence is a replaced and decorated with the logo of Charles' choice.
