Old Stero Electronics

I'm sure most of you old hands already knew this. Maybe a few other noobs like me didn't.

Keep an eye out for old stereo electronics built in the 80s - early 90s. Most of them have metal covers, and various goodies inside. I found a old Technics stero system that had a amp, tape deck, timer, am/fm player, and something else. Looking inside the amp I see a massive alum heat sink the length of the box. I also see a good bit of copper. So these could be worth picking up from CL, etc. if you see one.

This system I'm selling for $75 to a audio freak. I have a few other stero type items to either part or sell. If do part them I'll do some pictures.

I have been finding these, they all seem to have a STK4038 or similar chip. Sometimes two. They are rated at 50 watts per channel.

Because everything else is IC, when its broken its broken completly.



I have been saving up the power supplys & the STK chips, one day I might even make a amp from them

I love to find stereo receivers and cd players with the metal covers and also metal bottoms. BIG alum inside some. Record players are killer too with that big disk. lots of guys just cut the cords off. I think what a bunch of amitures.

Usually with stereo equipment i'll test it first to see if it works. My brother was moving and was going to leave his old Technics stereo equip and cd player in his old house...cd didn't work so I scrapped it, the receiver sold on C/L in 2 days for $30. I got a load of old radios one time, they were pretty much all crap except for one little gem I took to school, not too loud and fits in my toolbox nicely. And I got a nice Kenwood receiver staring at me from my entertaimnet center right now, some guy dropped it off at my house one day and told me his wife didn't want it in the house anymore. Some of the inputs don't work...I'm not sure why, but it's in really good physical condition.

'amitures' haha, its 'Armatures' (they just got shafted..)

The STK4038 chips that are in most cheap home stereos have a Ali backing plate & inside theres 4 copper squares, about 8mm x 6.5mm and theres two silver wires attached to each of the squares.

Well I'm sure they are silver, right colour & softness. They are 0.1mmdia & the total length of the wire is about 50mm long. (theres 8 strands, each strand is about 6-7 mm long)

Actually...it's amateurs.
