    yes, saw those posts. 16 is on a 500c and the 400 has no real estate in the same area. Post 17 is a 400, but my set up is not in a slick box. I may consider hanging it off the back end as Luis did.

    Ok, here is my solution to mounting my first IBBA on a fisher 400. Actually, this is my first IBBA period. This is a real stretch for my level of expertise, I do hope I have all the components properly installed. I am a machinist by background, so the mounting part was easy with my milling machine and some drilling and tapping. I also bent the heat shield more obtuse to make room for the IBBA.
    Now, my huge task in front of me is hooking up the IBBA. Is there a YouTube out there explaining where to hook up everything? I think I read some components actually come out of the stock system? Uggh.

    Hi ducati2: I made this illustration of how the IBBA board fits into the Fisher 500 simply as an aid to myself. I separated out the board with dashed lines to show its components and where in the circuit it must be placed. I also added some other mods that have been written about in AK. This may help or not. The 400 implementation should be the same, except the component numbers will change. Due credit must be given to Mr Gillespie. ibba(2).jpg

    NICE !!!! I guess all I need now is PIN numbers for the 400 connections.

    Took the 800-C out of rotation so here's an IBAM pic:

    IBAM in my Fisher 800C.
    It has been dormant for decades but is working again, thanks in part to some great help from fellow members.
    As one might imagine, there are still a few bugs to work out.
    I'm also in need of a front panel.
    Thanks,
    Phil

    Here is the IBAM I installed into Fisher 400. Capacitor values were modified later when EFB was installed.

    Finally got my IBAM installed in my 500c and I have a question before I finish wiring it up. Should the two ceramic caps (C82, C84) be completely removed from the circuit? They’re the caps on each terminal strip going to ground. Sorry if it’s been addressed before. Ok, bedtime!

    I don't recall the original instructions calling for their removal. In fact, the last 500-C IBAM I did left them there.

    Ok, so after separating my two grid resistor pairs (R121 & R22) (R123 & R124), these ground caps will only be connected to the resistors going to V9 & V11 now, correct? Thank you!!

    Not totally finished wiring yet, but I thought I’d post pics. I actually rebuilt the board after the initial pics to get things to fit right, but you get the idea... with thanks to @bhamham for inspiration.

    I used 18 gauge wire, which was probably too thick... it was a real pain to maneuver and route through everything. The hardest thing about doing an IBAM isn’t building it, it’s figuring out where to put it!

    Impressive, very nice work. A lot better effort than mine! I like where you placed it - very clever!

    Nice job on the circuit board. You sure made it look clean. I've attached mine. The plastic ties have since been removed. I also insulated the circuit board bottom from the chassis. I recheck the amperage from time to time to ensure the tubes stay within +-.1A of each other. Thorne
