Ultralinear Guitar Amp (8): Chassis Prep (cont.)

Nothing like actually getting down to business!

The chassis needed one more modification.
The extra long back was sawed off, leaving about an inch;

The extra piece was also sawed short, to match the height;

This piece has the bend and chassis-bolt nuts which take the back bolts from above.

The piece is bolted to the rest of the chassis, to give a strong,
level surface for mounting the transformers and tubes.

As a result, new holes will have to be drilled in sides of the wooden Fender cab, to line up with the side-bolts.

Good news is, most of the front panel can be re-used, the old way,
with chassis-mounted knobs and point-to-point, using a turret board.

Here's a closeup of the Boltec 100watt UL transformer, with painted bells.
The 'burnt look' was created with a crackle-paint, sprayed lightly over the white.
It gives a hint of the mayhem to come from this best guitar-amp ever built (tribute).

Now the fun begins! LAYOUT Time!

Nothing like a new amp project to get you all fired up!
