    HAM Radio Relevance Currently and Personal Reflections.

    That’s correct. It’s not the only way. But if you’re into ham radio, it might be the only way you WANT to communicate. Just because technology has moved forward doesn’t mean you have to change how you communicate. Many ham’s have nice setups AND SDR too. Doesn’t mean they use SDR more or even...

    capacitor replacement help

    Sure, go ahead and buy the cheap LCR meter. I would go further and buy several different inductors and try them all with exactly the same set up. My Ohm (UK) monitors were expensive back in the day and sound great with my Denon amp. My Mission speakers sound much better through my old Marantz...

    capacitor replacement help

    Yeah, buying from a reputable source would be RS Components, Digikey, Farnell etc not hificollective!. No wonder you pay through the nose:). Apparently, an audio grade inductor should be a solid core construction to avoid microphony. Then they say air core is audio grade. I wonder if...

    Size discrepancy in 15R 330W Platinum Lamps

    Hi @partyanimallighting It may be that different manufacturers have slightly different diameters?. Philips have 15R’s with a diameter of 58.5mm. Spec sheet. Also it’s 300W not 330W. Very frustrating for you though. Martin

    Sansui 7070 Left and Right Output Issue

    You are telling us about ‘C07 & R33 etc. We don’t have the schematic or board in front of us. If you can, lift a leg of the resistor out of circuit to measure it. The measurements can be influenced by other components. Are C07 and C08 in series?. Did you clean the pots and switches before...

    More than likely. We all learn by our mistakes!. How are the rail voltages? Martin

    Generating 24VAC Output (2 Amp Capability) from 36-40VDC

    Sorry, but you sound like a robot! Hal’s niece or nephew?. People are trying to help you but you give no real world response. I suggest a thank you for previous efforts and a reason why those work for you!. Martin

    Sansui 7070 Left and Right Output Issue

    Welcome @coastman49 , You seem to know what you are doing. 17mV is not excessive but may show signs of oxidation on the trim pots. Were they extremely sensitive to adjust?. Try cleaning them. I personally would have brought the mains voltage up slowly over 20 minutes or so as it’s an old unit...

    Generating 24VAC Output (2 Amp Capability) from 36-40VDC

    May I ask why a transformer can’t be used if the module has AC? Martin

    Can some ID this component for me ? Thanks

    Agree.. try a search for BZT03C15. Although rated wattage unknown. Actually, Vishay here. Martin

    Impossible to say. You don’t know how or what you need.

    Ok. You will certainly learn on this forum (I have) but you need to specify a problem or something you don’t understand after doing your own research. Martin

    Nothing wrong with a dream but you need physics, science, math and electronics to achieve yours. And to be a leader in the field within 5 years? You better start studying. Martin
