    Sony reel to reel tape recorder inquiry

    Your first guess sounds plausible but the second,..errr, ...not so much. :) Chris

    Sony reel to reel tape recorder inquiry

    It may be easy to delete but I'm already buried in more of it than I can tolerate. But I'm glad you guys did! :) BTW, how the hell could the OP miss that? After all he has this thing in his possession! :confused: Chris Chris

    Transformer output

    Actually, you can calculate what your available 220V current will be by using some basic Ohms Law. Chris

    Loss of voltage with MOSFET

    I forgot something in my last post. We should have asked for photos of your test setup a long time ago. Please do. Chris

    Loss of voltage with MOSFET

    The first thing I must say is you get 5 gold stars for clearly answering everyone's questions. Honestly,.. it's like pulling teeth sometimes! You're a refreshing change! :) Now about alligator clips... EEEEEEEEEK!!! :eek: They're a dichotomy. Indispensable and yet the most ill devised or even...

    Motorbike KERS problem

    Somehow I missed that this is a 3PH source and bridge. This explains the 6 diodes that had me scratching my head. None the less it doesn't change my comments in my last post. Please mark on the schematic the points you're shorting when attempting to brake the motor. Chris

    Simple stall over current 12v dc motor protection?

    Alec, it looks good but I was unsuccessful in opening the .asc file without the prompt I mention in the next sentence. I then updated LT Spice but when it loads the file it prompts that it can't find the Pot and the OpAmp. Rather odd. What do you think that's all about? I doubt it but did you...

    Motorbike KERS problem

    Eureka! It just dawned on me what the problem is. The regenerative EMF from the motor is the same polarity as the source. Looking at it from the motor's point of view, the (+) motor terminal is looking into the Cathodes of the bridge. Therefore braking current will be blocked when shorting the...

    Simple stall over current 12v dc motor protection?

    Ah dats Alec, nice design but I think a manual reset would be safer. Ouch! Chris

    Loss of voltage with MOSFET

    Perhaps some clarification of your statements are in order. Your schematic indicates a battery connected to the charger's output but your statement above belies that. Does your circuit include the battery or not? If the answer is no then the problem is obvious. If the battery is absent the whole...

    Consider this a yes vote but I guess that would be Mods & Administration. Chris

    How can I hook up my usb speakers to a battery pack?

    But Tom replied with this?? Why does it work now? Is ":3" an ASCII smiley or does that mean Tom stacked three 1.5V cells = 4.5V and that's why it works now? Chris

    Sony reel to reel tape recorder inquiry

    Well, it looks like you two signed up to access the schematic and images. How wonderful to see and remember a time when manufacturers provided a schematic! Anyone have a guess as to why S7 & S8 are in series? Is S7 or S8 an enclosure interlock switch? Chris

    Help with a wiring circuit

    Hey, if it can transform that into a schematic for me I'm game! :) On the other hand I've never been a big fan of ASCII schematics either! :confused: Maybe that stuff can fix that too? :cool: Chris

    This link says it was provided with earphones. So logically there should be an earphone jack. http://www.hifiengine.com/manual_library/sony/tc-105.shtml Chris

    Motorbike KERS problem

    I sure wish I knew that over the past 50 + years. If I did I wouldn't have wasted my time wringing out all those suspect bridges. :) Chris

    How can I hook up my usb speakers to a battery pack?

    Sadly, I'm increasingly finding posts like this that scare the hell out of me. What am I missing that a USB (5V) amplified speaker now works fine on a 1.5V battery? I'm increasingly beginning to believe that my reading comprehension has boarded the 4:15 and gone West! :eek:o_O:confused: Chris

    Regulate from 12v to 3v?

    If you're loosing sleep over 300mV,.. don't. It's not significant enough. Chris

    Help with a wiring circuit

    It's moments like this that scares the hell out of me because I don't know what I'm looking at in that pseudo schematic. What ever you're drinking or smoking, I want some! :D Chris
