ODS Eyelet Boards
In the .pdf's below are all-eyelet versions of the ODS PCB's and preamp eyelet boards TAG member JBorders previously had made up for sale. The eyelet versions have the same overall dimensions and mounting centers, which has become the "TAG standard" to which other members have had chassis fabricated for sale.
The original intent was to replace the PCB/Preamp board set, which did not match any original Dumble ODS, and so there are differences with respect to the (authentic) layout drawings posted on TAG by Tony Albany. The preamp board closely matches Dumble's layout, however, so any important component interactions are preserved. The most notable difference is that all of the power supply filters are located on the main power supply board, so the remotely mounted B+5 filter capacitor seen in the layout drawings is not needed. The FET board layout required extensive rework for eyelet construction in the same dimensions as the PCB, but it has been proven to work well.
These boards can be configured for any ODS variant, including HRM and Bluesmaster using the small daughter board. Note that the OD and PAB relay board connections for all variants are shown for "OD on" when the OD relay coil is energized. Some original amps were configured in the opposite way.

Re: ODS Eyelet Boards
No trouble at all. A universal relay board has been added.

Updated with relay connections for Skyliner OD/PAB, and corrected relay diode orientation. :^)

Re: ODS Eyelet Boards
I draw up the eyelet boards in CAD. If anyone wants a set, let me know I'll get some made.
