Blacet Time Machine – construction photos

Here are the photos of the construction of my Blacet Time Machine module as
adapted to the MOTM format on a Stooge panel. Click on the thumbnails for the
real photos. The photos are also linked directly from the assembly document.

4 pot wide, long version bracket – drill new holes

Nylon mounting hardware

Holes drilled in the PCB for the nylon hardware


Notice two leads were not trimmed, but rather bent over to avoid trimming. This will be connection for bypass switch mod

PCB with all components
installed, ready to start attaching wiring. No modifications shown on this one. 


Wire attachment for the bypass switch modification. These are connected to those leads we did not trim. Heat shrink required for insulation.


Bottom of PCB after all jack wiring added. LED & bypass switch wiring also seen. Heat shrink added to protect wires from sharp component leads


Bypass jack removed to give access to wiring LED 

Bypass switch with 100K resistor installed. Need heat shrink to insulate it


Completed front panel
shown below:


Trial fit with large Bournes pots – not much room between PCB and pots


Trial fit with smaller Spectrol 148 or 149 series pots, and one center detent carbon pot


Detail of tempco resistor


back-to-back diodes for DELAY CV modification


Same diodes with some heat shrink, now ready to install on the PCB



Pots prepared with wire lengths necessary for connecting to PCB


Top of PCB after pots are connected

PCB at second board wash
 


View of the DELAY CV modification 2 diodes & 1K ohm resistor added


Bracket and PCB mounted to front panel using 4 pots
 


Completed module shown from the back. Chips are not yet installed. Blacet recommends some voltage checks and adjustment on first power up before installing chips.
