Congrads on your cell Steve,it looks just like i had in mind to make mine but 270E in machining only(i could buy a lathe for this money),i quit this setup.I will make it like Russ's,each cell separated.Why 4 cells?How are going to drill the conectors holes centred?Did you made a bottom cap?How the shop made your slots in the anode?where did you found the imperial diameters of the drill bits,i searched for years here and could not find 12.7mm drill bit...etc...

Thanks Ady,

Yes, the cell has a bottum cap. I am getting it ready as we speak.
The slots were made with a mill.
The shop had all drillbits. So the i orderd were not needed...
I have 2 of these 4 anode cells. So in totall i can go to 8 in series..

If i can help you...

ok,thanks.I will make mine at an private shop(i'm done with firms,VAT crap) thats why i ask you machining techniques so i can tell the man how its best to do it without damaging parts.Its made like this?
list=UUEGe7GasoADRNz6wfHM91sQ

Steve if i get the money would you order some ss tubes from onlinemetals?I will pay you in advance.I mailled them and nothing.Thx!

40 euros for 10 SS springs...
Way too expensive here..
But i bought them any way..

Holly boy

here i made them to the spec about 70 dollars for 100 springs... it was cheaper than the ready to buy ones at the screw center like 8 dollars each..

anyway you will see its worth! there won't be leakages on the electrical connections, nor bad contacts!

By the way are they very hard?

lots of work here too! i finally have it, its just ready for testing.... the only thing now its that the 70 ohm resistor in parallel with the primaries kind of heats up very fast...and the primary itself also gets pretty hot at extremely low frequencies...


my chokes are onto a arrangement of two pairs of cores forming a cube... so there is one leg left for the primary and one for the feedback coil... each in its isolated bobbin cavity

well you may say this increase the magnetic path length, i don´t really know how does it interfere,....

the coils were wound all in the same direction meaning that the start of the wire is aways closer to the core for example... this makes easy to determine what coil will be connect to where...

it may also have to do with the capacitance between the coils and the core itself so itself also depends on how you connected the coils...

to be fair enough i think the direction you wound it should not have so much importance,, of course it could not give the perfect performance not improving the parasitic capacitance..but i guess it not detrimental for the reACTIOn to happen... any way i wound all in this way...

also i found a way to fix the two transformers to a place such i can transport it without moving wires... see in the pic

Hey Steve i´m already testing!

How about your cell?
