I just >need to do the research on new controls, how to interface the turret >and other stuff, and then go for it.   Actually, your biggest problem will be decoding the English translation of the manuals from Chinese.   I don't think you'll have any problems interfacing to a tool changer, tool turret, or power tailstock. The counter can be replaced by a shaft encoder. The lathe version of the cheap controllers that we used had provisions for all of these and more.   However, you're correct to question whether it's worth replacing a working and reliable machine simply because of the non-availability of one hybrid. Such conversions tend to be a one way affair, where it it impossible to put things back after the conversion begins.   I would take a known dead A-RV06 hybrid and do whatever it takes to reverse engineer the circuitry. I couldn't find anything with Google search. Initially, an X-ray photo would be a good start. Then, do a chemical attack on the conformal coating which I can't identify from the photos and can't remember from the real thing. If it's hard, it's probably epoxy. If soft, silicone epoxy or urethane. Try heat, acetone, nitric acid, or hot MEK to soften the epoxy.   This is for a COB, but offers a clue as to how it can be done: <http://www.kaibader.de/exposing-a-chip-on-board/> <https://www.youtube.com/watch?v=hQ5hXEK35WI>   This looks like the back of the hybrid: <https://i.ebayimg.com/images/g/glcAAOSwgSpbs5Pj/s-l1600.jpg> and might be useful to identify the large parts.   Once you have access to the wiring and some of the components, measure the passive parts. Look for laser trimmed resistors. Try to identify the active components. Eventually, build a schematic. Then, try to design something that works in the same manner, but which uses modern components. I once reverse engineered the hybrid RF front end for a Cushman CE-6(?) service monitor, which I ended up replacing with two MMIC chips.   Good luck.   -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558

It doesn't matter, though. As others have said, it is unlikely that you could ID parts and replace just what went bad. It might be easiler (but still very difficult) to use one of the newer single chip micros or hobby boards to emulate the entire bad circuit board's function.   Pat

To Jon and Jeff, Yes, I have considered replacing the control. And I consider it more every day. I have done this before and it worked well. This machine has a turret, tailstock, and counter that would need some sort of PLC programming to interface with the control. I might need to learn ladder programming again. And you are correct Jeff, I shoulda provided the control info. The control is a FANUC 3T. Tha part is a FANUC A-RV06. The problem with changing the control is that I need enough time when the machine is not needed to make the swap. The bigger problem is that the original control has, until recently, been robust and completely trouble free, and I am nervous about ripping it out. I just need to do the research on new controls, how to interface the turret and other stuff, and then go for it. But now I have parts to run. Thanks eveyone, Cheers, Eric

The reason I wondered about the hybrid is not to fix it but to find out what it does so that I can figure out how to test it. The same board keeps failing in the control and I don't know why. The counter is different than just a a part counter. It increments by an M code. So only if the program has this code does it count. Once it reaches a pre-set number it send a signal to the machine to stop once the program running ends. The control itself has a switch for continuous running that works in conjunction with the counter. For many jobs this feature is a huge plus. I load stock and the machine keeps making part after part. I can program the machine to make some many parts and then stop with another M code but if the program needs to be restarted for any reason, which is common when setting up, the count is also restarted. The counter only counts when the program actually finishes a part. So whatever new control I put on must have this feature. It is very convenient and saves lots of time. Eric

tubeguy@myshop.com: Dec 18 05:21PM -0600 I got an old 1930s Crosley AM radio. It needs to be recapped and a few other things, such as a dial string and new power cord. Anyhow, after chopping off the bad power cord, I applied a temporary cord and the radio does get sound and radio stations. (Along with the hum from the weak filter caps).   This radio has a beautiful old wooden cabinet, so I am going to restore it completely.   Anyhow, someone replaced the old electromagnet (Field coil) speaker with a permanent magnet speaker. But what they did is sort of odd. I know that speaker coil served as a filter choke, in the power supply, on those old radios. What they did, was saw off the rear of the old speaker, and mount it to the chassis, with that magnet loosly sitting on top of the sawed off rear portion of the old speaker.   What I now have, is this large magnet sitting next to the audio output tube, and very close to the power transformer as well. That magnet is quite powerful, in fact I magnetized a screwdriver with it.   My question is whether that magnetism is going to affect that tube, as well as interfere with the power transformer's function?   If this is a problem, how to I determine what size filter choke to buy to replace it? (Or isn't that real critical)? If it's not going to cause any problems, I may likely just leave it as it is, except to apply some sort of adhesive to prevent that magnet from falling off the sawed off steel piece. Because as it sits now, if I set the radio on edge, that magnet will fall off and could smash tubes in the process. I have never seen this sort of thing done.... Very strange!   By the way, the audio output transformer appears to be glued on to the speaker frame, but it is tight, so I am going to just leave it.

(Along with the hum from the > weak filter caps).   A few things:   a) As this is a 1930s radio, be careful not to add too much additional capacitance when replacing the filters as you do not want to raise the B+ beyond specified levels. This is hard enough in any case as it is likely that the line voltage today is higher than it was when the radio was new. You could add a bucking transformer on an outside receptacle - you want to be somewhere around 115 V or so - or you could run everything off a Variac, again if your wallplate voltage is over 120 VAC.   b) An outboard choke would be ideal. "Back in the day" those chokes would be anywhere from about 1 H to about 5 H, and rated from about 20 ma to about 60 ma, at a B+ of about 350 VDC or so. Pretty much as anything is better than nothing, as long as your replacement choke will handle the current (depends on the output tubes), even a lower-value choke will help. One-of-many links is here for one-of-many chokes that will handle what you have, and then some, but is readily available:   http://www.classictone.net/40-18003.html It may be mounted anywhere that is convenient and safe.   c) Stray magnetism will not affect any part of the radio. Placement of said parts should be a matter of convenience and safety.   d) If it is your intention to retain the old field-coil for its value as a choke, I would strongly suggest that you replace the entire speaker with a (new/different) unit, and remove the stray coil. It carries the entire B+ supply - a lethal voltage at lethal current levels - and it is neither secure as you describe it, nor designed for that sort of installation. If you are going to retain the PM speaker, use an outboard choke properly mounted and secured. There is no shame in that, by the way. Just as there is no shame in putting modern oil in a vintage vehicle.   Best of luck with it!   Peter Wieck Melrose Park, PA

tabbypurr@gmail.com: Dec 19 07:45AM -0800 > Best of luck with it!   > Peter Wieck > Melrose Park, PA   Secure the choke, there's no reason to remove it. Replacing things without reason on prewar equipment is bad practice.   I don't know what you do/don't know. Valve rectifiers have tight max capacitance specs, radios put as much C on them as they can. Don't increase C or it will overload the valve. There was good reason in the choke setup rather than just using a bigger cap.     NT

However, the one thing that cannot be reverse engineered in a mechanical system are the product tolerances. This becomes critical when dealing with tiny parts like MEMS devices, rotating memory components, and tight tolerance fasteners. Long ago, I was marginally involved in some industrial espionage. The only things taken were some key component tolerances. Everything else could be deduced or measured from the purchased product.   Also, the end result of reverse engineering is not always an exact clone of the original product. More commonly, it's a "work alike" device, that has all the key features and patent violations, and carries its own collection of component and product tolerances. Close is usually good enough.       -- Jeff Liebermann jeffl@cruzio.com 150 Felker St #D http://www.LearnByDestroying.com Santa Cruz CA 95060 http://802.11junk.com Skype: JeffLiebermann AE6KS 831-336-2558
