Bull
Laney Klipp 100
An old Laney amp that needs som tendering.
Blows the main fuse. Tinkered with as it has a master volume pot installed and traces of other activites.
Components close up.
Checked the power transformer and it seems to be functional. I’ll start with recapping them old electrolytes.

On the workbench
Nothing like the smell of a newly painted stompbox. I’m thinking red knobs on this one.

Every single time!
Giving my Les Paul new strings. Threre’s blood every time I do this….

Boss DD-3 repaired
Checked the switch for D.TIME due to the problem of changing from 200mS to 800mS of delay. Found it’s not the cause. Had the wiring from the switch resoldered and it’s hey, it’s back in normal operation! Also fixed the knob for E.LEVEL wich was glued in place.

Mullard GE diodes
Found these vintage OA5 germanium diodes in the box of vintage stuff. Beutiful diodes indeed. Got to make something with them, just don’t know what? Anyone care for a custom built pedal with these beuties under the hood and in what circuit?

Lady Dirt in stereo
Some pictures from the work bench.
I like how the circuit board appears in black and white.
And a gut shot.

Boss DD-3 repair
Got a Boss DD-3 on the workbench.
Got some problem with the pots I was told. Nice and clean on the solder side of the circuit board.
Here’s a picture of the component side.
When played it seems the select knob has trouble changing from 200mS to the 800mS setting.

New pedal under design update 2
Here we are in the work of my latest design. I’ve fitted the complete circuit in a Hammond 1590B chassie. Though the tweaking continues.
Stay tuned for more info. Earlier post.
