Okay a heap of parts arrived today and I've started fitting stuff. First of all I wound the screws for the MOD 5 into the Rockboard to cut the threads, then I wound them out again and tested the fit of the module. Then I attempted to fit the power cable to my power supply and realised that it needed to be turned around for everything to go in nicely, so I peeled it off the velcro and then put it in the correct position. The IEC socket etc was all good but the rubber boot to go over it was too large and the spade connectors are too clumsy. So I will solder the wires to the terminals and I exchanged the boot for the smaller size. This involved a trip to Jaycar, which quite frankly seemed like it could have better quarantine and I washed it and my hands very thoroughly when I got home. I also flipped the Tray over to the other side and realised that the power supply on the tray fits behind the module without dramas. So I called the local music shop and asked if they had one in stock, which they did, no now I have two. The Rockboard Natural Sound Buffer is slightly lower in profile than the power supply and much smaller in footprint so it will mount on top of a second Tray behind the MOD 5 no worries. The Rockboard buffer was under $50, the best value buffer on the market, and the Tray was $17, so that was cheaper than other options for a small buffer that fits under the board, most of which were over $100 or had to be imported from China (not ideal at the moment).
I cut the end off of a 0.5m angled end IEC cable and I will solder that to the the IEC socket / EMI filter, then put the boot over it. It will run up the centre brace on the board to the power supply.
Here are some photos.
The first is a size comparison of the RockBoard Tres 3.1 and the Pedaltrain PT-2.
Here you see the power cable after I chopped the end off. You can also see the EMI filter, and the angled power cable end that I will fit to my long IEC cable that I run out to my pedalboard at shows. The rubber boot was too large and had to be exchanged
Here's the front of the MOD 5
Here's the rear of it
Here you see how the power cable will come out at an angle and run to my right, which suits me as I set up stage left. You also see the MOD 5 mounted into the board
Here you see the socket
I threaded the cut power cable through the centre brace like this
Here you can see that I reversed the power supply
This routing of the AC power looks neat to me
Here you can see that the Tray with the power supply on it easily fits on the other side behind the MOD 5, demonstrating that there is plenty of room to mount the much smaller buffer that way
More obvious here
So I bought a second Tray today. Note also the smaller rubber boot
I used a razor to remove the covering on the end of the power cable
I managed to get this Boss cable kit old stock, way below current wholesale price
