Re: 100w 2nd Gen. ODS build
Thanks, Martin! So just to clarify and to see if I’m grasping this, I need to remove the 1k on the supply board and run the brown wire (12v lead) I have on pin 3 of the chassis din directly to the regulator output eyelet on the board (where I have the green wire running to the regulator tag strip wh...

Re: 100w 2nd Gen. ODS build
Great! So would I have to change any wiring on the supply board or just leave everything as is and wire the footswitch as shown with just two switches?

Re: 100w 2nd Gen. ODS build
That’s a cool idea! Is there a wiring layout for that?

Re: 100w 2nd Gen. ODS build
Great! Thanks, Martin! Since I’m running two relays where should I put the second 1k resistor for the footswitch?
Thanks,
Dan
Thanks,

Re: 100w 2nd Gen. ODS build
Cool! Thanks Martin! This thing might actually work when I’m done!
Was my assessment of the DIN wiring a few posts ago accurate, too?

Re: 100w 2nd Gen. ODS build
So I actually managed to wire it correctly?

Re: 100w 2nd Gen. ODS build
Thanks, Martin! So if I’m reading the schematic right I would just get rid of the orange wire I have running from the cap positive to the relay coils since I already have the green wire running from the 1k to leg 3 of the regulator? Then I could just connect the relay coils to the tag lug connected ...

Re: 100w 2nd Gen. ODS build
Hey Guys! I have the relay supply wired up but hit a snag with the DIN wiring. The plan is to have the FET be footswitch only. So would the wiring be as follows or would I have to wire this like 102 and 124 with the OD and FET switches on the back panel? 1 Manual/Pedal switch 4 OD relay 2 Ground 5 F...

Re: 100w 2nd Gen. ODS build
Thanks, Dan! I have the relay transformer wired for FW and the diagram I’m following is Martin’s modified version with the added regulator minus the 56R found here…

Re: 100w 2nd Gen. ODS build
I think my issue was I was actually combining the stock regulator layout with Martin’s modified layout, basically I just need to follow the regulator layout for 102 or 124, right? Also got V6 and V7 mostly wired up.

Re: 100w 2nd Gen. ODS build
It’s been a long while but I’m back to working on this thing. :) I have the regulator board almost wired up but have a quick question. So as far as grounding the cap negative and diode anode, is the blue wire I’ve run to the strip sufficient or do I need to also ground from the cap negative eyelet? ...

Re: 100w 2nd Gen. ODS build
Thank you, Martin! Just the clarification I needed. Very nice work, too! Which ODS variation did you build and how do you like it, if you don’t mind my asking? 
Thanks,
Dan
Thanks,
Dan

Re: 100w 2nd Gen. ODS build
A little more progress, but wanted to ask a couple questions before I went any further. On the 1Ω cathodes is it best to ground them in pairs, individually or am I over thinking and it doesn’t matter? Also, as far as the 100 Ω filament grounds, does it matter which sockets I run them off of? I was t...

Re: 100w 2nd Gen. ODS build
Thanks again, Martin! You’ve been a big help! When my parts show up I’ll post some progress pics. 
Thanks,
Dan
