  I may be confusing you more because I don't have an instruction manual in front of me. Follow that if in doubt.

  "one lead across pins 1 & 8 and the other lead connected to another resistor in the next socket. between pins 1 & 8, a wire to the bias test points. where the 2 leads of the resistors connect, a wire to the psb star ground"

  above is all correct.

  "i get continuity between the bias test point and ground - whether power switch or star ground."

  that is not correct. you should have 10ohms between the test point and ground. ie pins 1 & 8 only connect to ground through that resistor. I'm not sure how, but you must have either pin 1, 8 or the bias rca center pin accidently shorted to ground.

  Check resistance between each bias test point and ground with the amp off. Should be 10ohms.

    Hi, congratulations, I hope to be successful too.
    I also need help with the ELLA beacuse I do not have the instructions.
    Can somebody provide me the instructions for the KIT?
    I have seen several schemes, so I think I can understand most of it, like 22k potentiometer for bias from the 50 Volts to C connections on PCB but some aspects are unclear.
    I know it is a tough job to scan the manual, but it will be very helpful if somebody can provide me the instructions.
    Thanks

          hey alberto, well you got that sorted out now so its time to study the manual and get cracking. i had fun doing mine although there were times when things got a bit hairy as you can see from my posts but i had more fun than hairy situations ;) - in fact had so much fun that im kinda having withdrawal symptons from not having solder fumes to inhale.
          cheers

            Ended up and working with a very nice sound.
            I have only some doubts:
            The actual bias resistance measured is 10 to 13 ohms depending on the pot. Do I need to adjust the bias corrspondingly, that means 0.4V for 10 ohm and some 0.52V for the 13 ohm to have the same current?
            The power transfor wiring colours are brown=0, blue=110V and red=120V,my ella is wired for 220V but actual net Voltage is 234V is it better if I rewire?
            Some times the soft start relé is not activating, some times yes, is this linked to the power transformer wiring and the actual voltage on relé?
            Output volume is quite high, would it be better if I change to 100k potentiometer for better regulation?
            cheers

              hi alberto, im afraid i cant answer your queries - im very much a newbie and still learning the ropes - the best persons to advise you would be brian cherry or zarniwoop or any of the othe forummers who have a better technical grasp of things. may i suggest that you re-post your message addressing either of these 2 gentlemen.
              cheers

    hi zarni - thanks for the reply. i just took apart the bias resistor and bias test point network on one tube socket - no shorts between the pins or the rca centre pin but when put back together (with croc clips), the rca bias centre pin is continuous with ground. is it possible that the bias resistor could be bad? - havent had much experience with wirewounds or 10 ohm value but other resistors in higher values do not have continuity between each lead. this one does - which means that the the rca centre pin is being hooked up with ground through the wire from the ground cluster of the pcb that joins the resistor leads between 2 sockets. oh man im bushed. sorry for troubling you zarni - im going to bed now - its past 3 am here.
    thanks again
    mikey

      Strange.. maybe it is a bad resistor. Have you checked all four of them? It sounds like you are focusing on one of the 4 sockets, but you don't say if the other three are checking out. One resistor may be bad, but all four... not likely. That way we can be sure its the resistor and not the wiring. You should take the suspect resistor out of the circuit and measure it with an ohmeter. Usually a resistor will open-circuit if it is damaged, but its possible that it shorted, or that it was not good to begin with.

      No trouble at all, btw. I'm sure you will get this sorted out and have a perfectly working amplifier (and great sounding too, these are nice). gnight

        hi zarni, thanks for the encouragement - i was having the problem that i addressed in my earlier post with all 4 sockets - i undid the bias network on all 4 sockets and i can confirm that there is no shorting between the pins and the jacks. i procured fresh wirewound resistors of almost similar value - 10r/5w and surprise surprise - there is continuity as well. since they were going cheap - i got more of the same value from different vendors and same thing -continuity. a new lesson for me today - resistors of low values have contintuity. as the resistors that came with the kit are somewhat gnarled - im gonna pop in the new resistors and give it a go tomorrow and i will post what happens.
        cheers

          hi zarni, sorry for the shout but yes it works!!. and it works beautifully man:)thank you zarni and thanks to brian and G for the tips and the encouragement - im going to be up late - obviously - im looking forward to the burn in process - and, me being me, im already thinking of upgrades to it - but im only thinking - im not going to do this now - i will enjoy these stock - the only thing that is not stock about it is the kimber tcss wiring throughout. you are right about the sound of the amp - its amazing right now - i can only imagine that it would be absolutely spectacular after burn in.
          thanks very much again

            Glad to hear its up and running. It will likely "break-in" a little bit from my experience. Of course there are lots of possible upgrades/mods/tweaks, but I think you are taking the right approach and getting used to it stock first. I'll share some of my mods in a future post, but they certainly are only optional.
            Enjoy,
