Brian,
You must “TIM”…
Trust in Martin. He always comes through in the clutch and will never steer you wrong
Looking good - keep moving forward and you’ll be there before you know it.

I love using this solid wire, you bend it and it stays where you put it. Stays tight in all the corners...

Re: Starting to populate the chassis....
Looks like you are making good progress!
What wattage are those screen resistors? You may also want to situate them more in front of the socket than over it for a little less heat convection.
On your footswitch jack, you will want to jump the case ground tab down to one of the conductor tabs. Most commercial midi cables will not connect the two case grounds through the cable.
Looks like you have the voltage regulator grounded at the terminal strip and the relay ground star. I am not sure this will cause an issue, but maybe better to pick one point for all of those grounds.

I would let the DIN jack case connect to the chassis through its mounting bolts, and move the relay PS ground wire to pin 3. That way the relay PS is only grounded to the chassis at the regulator tab and the terminal strip ground lug near the relay PS board. Ground the relay PS board to the terminal strip ground lug, which should have the regulator center pin soldered to it.dbharris wrote: ↑Wed Mar 13, 2024 12:09 pmOn your footswitch jack, you will want to jump the case ground tab down to one of the conductor tabs.

Re: Starting to populate the chassis....
I was also looking at those screens too and they look like 1/2W 470R. You definitely want to get something bigger like a 3W or 5W...

Re: Starting to populate the chassis....
Yeah, they're 1/2 watt, I can go bigger...

Your are correct, I didn't even think of that while soldering it on......Makes sense, I'll change it. Funny grounds do funny things!!!

Re: Starting to populate the chassis....
Martin's suggestion is a good one, to move your relay ps ground wire to the middle tab on the terminal strip.
Bigger screen resistors is a good idea. As Ian mentioned, 3-5 watt preferred there.

Re: Starting to populate the chassis....
So I'm trying to solder one of the coax wires. I can't get the solder to stick to the braided
Shielding wires, am I not getting it hot enough?, is it the wrong kind of coax?
It's the kind you use for cable TV, solid core with a braided shield.
The braid is silver colored, could it be stainless///

Re: Starting to populate the chassis....
I would get some proper RF cable, like RG-58. Should be no problems soldering to that. A nice to have is cable with Teflon insulation between the core and shield so it can take heat without melting.
Re: Starting to populate the chassis....
I'll give it a shot, Brian
Question, do the two coax cables from location "A" (black marker) go to location "B"

Re: Starting to populate the chassis....
No, those are going to the front panel "level"(marked A) and "ratio"(marked B) pots.
For a good understanding of the layout, you can reference the schematic that is in the files section for #124.
Re: Starting to populate the chassis....
So where do my marked “B” wires go, and thank you for your answer on the last question
