    While you are busy designing...is it possible to give me a design for a MUCH BUTCHER less prone to die, separate driver circuit...like a Mosfet BUZ type..there is plenty of room in the robot to add such things. AHH crap, Im putting the cart before the horse again...lets just get the original...

    Ok so to basically wrap up what has been done so far: -BEEPING IS WORKING -LED IN DOME WORKING -1 LEG MOTOR IS NOW WORKING- after replacing its interconnecting wires. I have reaplaced all interconnecting wires now.

    One thing about this stupid unit is that all the interconnecting wires are VERY fine, finer than any other project Ive worked on, and when one comes off of a connection there is NO RECONNECTING WITH IT. The wires are impossible to strip, and when you are able to strip them, you get almost a...

    OK, so I do have the Amplifier working and squawking away. I replaced the speaker with a 16 ohm plastic cone unit, and holy crap...its LOUD!!!!. Should I just go Bat Shit Crazy, and just replace every single stinking Transistor (AND Darlington) in the motor Driver circuitry ...

    The small "Smoke Stack" inside the yellow box is just decorative, and matches the original in the film. The small red dot that you have also pointed out is simply painted on. The LED actually has 2 wipers (that I have Tak-Soldered a LED to) that match with 2 metal rings on the base of the dome...

    Ok, referencing to ED's pix and comments: Just as I read and digest what you are saying, I will comment, as my tiny brain cannot do otherwise The Black :BLOBS" that you see on what I call the "Reed Switches" are actually black plastic "Slippers" molded on to allow the ends not to scrape or...

    -I have a remote now, I know it works because placing it near a AM radio gives me static when I press the button -I have the BEEPING going from the amp-this was caused by a common ground bridge falling out when I soldered a new battery connecter onto the switch...stupid stupid stupid!!! -I have...

    Ok, here is the Rf board, I can take more. The led is soldered across the wipers that usually connect into the dome The Round motor is the Dome motor, the 2 square motors arte for the wheels in the legs Want more pics....I will gratefully add

    EGADS SIR, youi are amazing.........You gave me a good idea, so I went off to you tube, and Ill be dammed, a sample of R2D2s Voice...which is basically 2 warbling tones, low and high, easily obtainable thru basic feedback.. It didnt come with a remote, but I finally found one, so as soon as I...

    CRT television not working anymore.

    I think that its time to put this beast down. The cost to fix...probibly too much, so take it out back behind the barn, and pit it, andyou out of its Misery.

    There are 4 leaf switches, so I can only guess that there are 4 individual tones...kinda simple...but that the way it was in the 70's

    Anyone interested in taking this unit and repairing it for me, this is probibly over my head??

    Well it doesnt really matter, because it no longer a amplification problem, its a problem that the board really doesnt work. When the switches that I mentioned are pressed, it doesnt make the sounds it should, altho as mentioned, it makes a quiet squeek on power up
