Nice to see the TM504 DM modules in use!

I've got no clue about electronics ..ive watched a few of your films,, now I have a bit more of a clue which mite be dangerous or not ..thanks for sharing some of your knowledge..👍

[@audionautica6843]

I'm glad you're enjoying - if you decide to have a go at electronics, make sure you start out with things that can't (easily) kill you!

[@AndrewReid-wb9ih]

thanks for that bit of advice however ime miles away from opening up an amp and waving a meter at it..but is a fascinating subject,,,@@audionautica6843

[@gustavochagui6888]

I am trying to recover mine, all is now working, except for when the treble is 100%, it sounds like voltage interference going through, and one resistor next to big capacitors R721 gets really hot and starts smoking. But if I bring treble to 80% all is good.. any ideas? Thanks

[@audionautica6843]

Sorry, not off hand. Perhaps check the capacitors.

A nice one, back in the days of FM stereo magic radio was the way to deliver remote content then, guess still is though superseded by streaming

That's right - in the 80s FM Stereo was still relatively new in Australia. Television was mono and most TVs had a terrible tinny speaker. Every now and then TV stations would make a big deal that they were simulcasting a big rock concert in FM stereo on one of the FM stations. Of course CDs were around, but I didn't get my first CD player until the 90s. For many people their first CD player was the one in their "multimedia PC".
