    AC Compressor blowing fuse

    Hi Jerry, according to what I have just read, a 1N4007 or 1N4004 would (or seem) to work well as a flyback diode. Leave your other wiring as it is. Just to complicate things...Antiparallel.:) Martin

    HOME THEATER AUDIO CUTS OFF

    The pdf is too large to upload here. But this is a snippet.. (* Depending on the sound mode settings and the source, there may be no sound output.) I suggest looking for the user manual. Martin

    HOME THEATER AUDIO CUTS OFF

    Have you got tools to check voltages? multimeter? etc. I'll try and upload the service manual here. Maybe someone can help with that. I initially thought the protect mode was kicking in but the relays should have cut power to the speakers. Until you said there is still a hum. Might also be a...

    HOME THEATER AUDIO CUTS OFF

    Hi Renwick, A couple more questions.. Do you have the user manual? Because it appears that the XTS button changes to channel 2 or something like that. Do you have all the speakers connected? Front, rear and centre. Are the speakers the correct impedence for the amp. 4-8 ohms? If you power the...

    Obtain the schematic circuit by pcb

    It appears you may have to manually place lines and components using 'PL' and 'GC' commands after scanning. Then the software completes the file. They have a complete section on getting started! As the saying goes, RTFM. Martin

    Noise issue

    I don't know what socket you have. But some have a test socket inside the cover. You can try and remove the two screws on the front and connect your phone inside the socket. Not sure this will help though as it's still the 'master' socket. If you have an IDC tool, you could check the wiring...

    Electronics Project - PLC

    Well, if you volunteerd and passed, congrats to you. I can't pass with studying!!! But that doesn't change your dilemma. That is some kind of serious practical side. I don't envy you. Sounds more like computer programming rather than actual hands on! The switches, buttons and lights are pretty...

    Pulse transformer

    Colin is a good engineer, but doesn't like the 555:D He has/had a website for beginners like me called Talking Electronics. Very informative and great little circuits. Martin

    Pulse transformer

    I knew you wouldn't be able to stop yourself chipping in. They sell them a lot smaller now.:p

    Pulse transformer

    That implies that it is indeed a very popular chip. I don't see any short comings! I see a successful chip that has sold billions. Every item bought from yester year to today have different versions. It's called 'updating' and 'improving'. The cmos version if proof of that. I could go on and...

    Pulse transformer

    I couldn't disagree with you more! This versatile little 8 pin chip has opened the electronics door for many a tinkerer like me and others. But that's just my opinion. Martin

    Can any body help me in making dual 24 Volt 5 amp Regulator??

    Yes, there are lots. But you specified LM7824 and LM7924. Both of which are 1 amp max. The L78xx series are 1.5 amp. That's what you linked to. This is what you specified you must use. LM7824 Martin

    How to yield sound from one jack plug to another

    Hi, that can be made very simply with a DPDT switch. And a housing box if required. I started writing this ages ago, but had to get my crispy duck out of the oven:) But Gryd3's explanation is better than mine so I found a picture instead.

    Does anyone have the manual for a tektronix t202 handheld 5mhzoscilloscope?

    Hi Hacktuss Looks like you might have to pay for that manual. They are like gold dust. Keep an eye on Ebay and keep checking in this forum too. I might get lucky and find one. Martin
