    The shields are there to keep unwanted, noise, frequencies etc, that are emitted from the tubes when powered up from leaking into other circuits, or tubes that may pick up unwanted microphonics, etc.
    Though the amp tuner etc will work fine if the shields are missing.
    Others like Larry will give a better technical description, than I can.

    No need for the technical description, that makes even sense here! Thanks

    They are absolutely there as a needed piece for shielding -- not for protection of the tube they cover. There are all manner of different sub and supersonic frequencies floating around inside of an FM Stereo MPX tuner:

    1. The received signal frequency.
    2. The 10.7 mHz Intermediate Frequency (IF) signal frequency.
    3. The 38 kHz stereo subchannel frequency.
    4. The 19 kHz stereo pilot frequency. Not technically a supersonic frequency, but close.
    5. The left and right audio frequencies.
    6. The 120 Hz power supply frequency, and
    7. The 60 Hz AC line frequency.

    These all need to be separated from each other. As a result, you will see whole sections cordoned off from others, or even built into their own box. The layout of a tuner is critical so that none of these different frequencies try to interact with each other.

    Dave beat me to it. Plus on the AMP and preamp there is a need for the same in places, like the phono stage for example. IT amplifies a lot more than the intermediate stages, and it's very suseptable to outside interference. If it has a mount for a shield (like on that 12ax7 in the 1st pic last set,) it gets a shield.

    If you look inside a tuner, tuner/preamp or a receiver there are whole sections shielded from the others by sheet metal walls. Same reason.

    Gentleman....I believe I am going to put the console up for sale because 1.) its what the wife wants, 2.) I prefer to have a unit that I can tinker with and this piece is much to original/rare for that, and 3.) I dont trust the Navy movers to move it without damaging the unit. Anyone interested or know who might be interested in purchasing it?

    Below is a link to pictures:

    Also, will only sell to someone looking to keep the unit intact. Already had offers to part out the pre-amp / amp for 3k; not interested.

    I wonder how long it'll take Larry to drive to the Bay area from Maryland?

    In the 80s I made it from San Fran to Asbury Park, NJ in the middle of December, (snow in the Sierra's to east of Donner Pass. Then snow again all through Wyoming, and more snow again all the way from Youngstown to Allentown) In about 7-8 days.
    But I was much younger then...

    Good luck with your sale. You should have no problem selling it!

    It'd be mine if not for the distance. Offer to buy the bride a new house with an extra "Presidential suite"...

    I can understand as these to consume a lot of real estate. It was actually the wife's objection that prompted the last owner of my Executive to sell. I thanked her for that, btw...

    I applaud you for not parting it out. Unfortunately, once it leaves a collector's hands, it's free game.

    Johnny; ROFLMAO. I did S.F to Baltimore in Nov 77 (10 days) on a Kawasaki 500 (H1). Snowed thru Eastern NEV thru Wyo. Fun trip, but I'd rather do it now from inside my S-10's. Try doing 115mph between Wendover Nev and SLC with a ambient temp of 35*F. IT WAS COLD!!!!!

    BRW: Much as I'd love to drive out and snatch it, I'm trying to divest a few of my consoles. Hell, look for another one when you get settled in AZ. The Executives from 61 to 64 are very good too. The smaller FISHER's from the Custom Electra and up (look at the line up's @ www.fisherconsoles.com)are usually very good and quite easy to work on. Below the Custom Electra the electronics are in one chassis usually.

    You are much much braver, or maybe crazier than I. Surprised you are still alive. :rflmao:
    The furthest I ever rode my Sportster was about 400 miles round trip. And I swore I'd never do THAT again.

    That will be fine. As this was the top of the line console, I just wondered what drivers Fisher used.
    thanks

    Philips fx82, here's the literature from the operations manual addressing the speakers. Also I attached some pictures of the left cabinet interior.
