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

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...

Thanks again, Martin! You’ve been a big help! When my parts show up I’ll post some progress pics.
Thanks,
Dan

So I did some work modifying the rectifier board for the fwb and also decided to add the voltage regulator to the relay supply. I’m working off of Martin’s 2nd gen mod and was thinking I can just do it with a three lug center ground terminal strip rather than adding eyelets to the board. As far as t...

Some good clips of a 2nd/3rd Gen. Now I really can’t wait until my parts order shows up.

Thanks, Erwin! Really nice build, by the way! Will modify my rectifier board today.
Thanks,

Unfortunately I don’t. Can’t really find any info on these transformers, only thing I can find is the schematic for the Deuce which shows a fwb.

Was just doing some research on the forum and came across norburybrook’s wonderland build using peavey transformers like mine. Apparently a fwbr is needed for these, all things considered will there be anything else I need to revise to allow for this? I noticed his diagram shows a 1 Ω instead of the...

Thanks again, Martin! Much appreciated! Will order a few more parts and get soldering. Which test jacks do you prefer? Also, what size resistor do I need for the cathodes?
Thanks,
Dan

Thanks, Martin! Really appreciate the help! So just to clarify, I’d need the 1Ω ‘s on pin 8 to ground on all four power tube sockets?
Thanks,
Dan

Hey everybody, been a while since I’ve had time to work on this but I’m thinking I can get it sewn up over the next week. I’ve had to reacquaint myself with a lot of info and have a couple questions. As far as the 100w 2nd/3rd Gen’s are concerned, is the power tube wiring essentially the same as 102...

Looks like the listing was updated with a gut shot.

Not much, but a little more progress…

Cool! Thanks! I have a 166J6 on hand, will that suffice?

I didn’t see your transformer recommendation in your original post, Martin. Wasn’t ignoring you or your advice. I got the 166JA12 because, if I understand correctly, the stock 2nd Gen supply board isn’t a voltage doubler. If that’s incorrect, please correct me. I’m pretty new to this stuff, the ODS ...
