Four 100th's aglow...

I need to get the real grid caps as well!
I have been waiting for the alligator clips to not make contact!

Brett - at the minimum - why not use Fahnestock clips on those grid connections.  It would be a shame to have a meltdown because a clip fell off. I'm assuming that you are using them in push-pull.  How does that work with that nice RCA mod iron that we both have?  Maybe that's the combo I should be planning on.

I dont know why more guys dont post some pix.

Because my shack looks like hell!  I got stuff strewn all over the place. But I guess that should be the impetus behind straightening it out some what.

They are all 'works of art'  Post it

The RCA seems to work great no matter what you do with it.
I used one in the push pull 812a rig modulated by 811a's and it was great.
I use it in the 3X4D32 rig with 811a's at 1200 volts and it works great.
I use it in the 2X813 rig with 4cx250b/4x150a,s (2000 volts) and the PPP 100TH deck at 2500 volts, and it sounds great!
I should sweep it and see what it really does.

4350 to 10,400 ohms seems to be a very handy ratio.

Nice hint Al.

Dang!  I have mod irons running out the kazoo now.  I have that RCA, I have a CVM-4 and I just won a Thordarson T11M77!  

I have this warm fuzzy feeling.  I think the RCA will be the first choice.  Thanks for the encouragement Brent

I just thought of something when viewing where you have that RCA.  During a recent QSO I asked how heavy it was ‘cause I tho’t mine weighed about 70 lbs.  I heard you get up and heard a clank and you came back and said “yup, it weighs about 70 lbs."  You weren’t running that thing at the time ----- were you?

No, I have a bunch of them.
I just shipped out a T11m77.
i used to run one of those in the 30K-1, and from memory, it sounded ok.
I bet the RCA sounds a lot better though!

I swept the 2x813 rig with the RCA mod iron in it.
Been running that mod iron for 6 or more years I think, and never swept it...
+- 1db, tested through the transmitter at 70% power, 50% modulation, 40Hz to 16KHz.
The low end rolls off slowly, -3db at 20 Hz....

DC through the core, I dont need no stinkin chokes....
