My work 1990.

Hello,

I recently finnished my retro style amp.
It is an current feedback amp on a single voltage rail of ~ 52v.
All driver and pre transistors are BC141-16 BC161-16.
Power transistors are ST MJ2955
The heatsink is from an old Philips X-ray power supply from 1966, originaly it had 4 germanium power devices on it.
The transformer is from an old philips reciever and i painted it black and re- applied the top wiring.
It puts out ~ 52v at 2.5 amps and this is regulated and then buffered by a 10,000 Uf capacitor.
The same capacitors are also used as output decoupling.
This amp is obviously not build for perfect sound reproduction but mere for the sake of old times though it sound very nice for what it is and put out alot of power.

I will post some pics of the build feel free to give your opinion

This is a 2x5 watt Amp based on germanium devices.
I have build this little amp 1 year before the amp in the post above thats why it resembles it in some kind (the copper revets for example).
It has a kind of warm round sound to it, though 5 watts is enough for easy listening, it lacks power when it comes to having a party or whatever.
So thats why i have build the amp in the post above.
That one delivers 30 watts per channel.
It only uses a BC154P gold pin low noise silicium transistor as preamplifier.

The rest is based on AD161 and AD141

Please comment on this little computer amplifier

Wow - AD161 and 162 - now thats going back. I remember when I was a kid seeing a 10W amp in Practical Wireless (I think) using these devices - circuit wa s built an Veroboard. Happy listening - will you publish circuits?

here is another toy ...a passive preamp with relay selector and shunt topology .... extremelly ultra quiet

enjoy the cassing ...its all hand made
curved grey aluminium glass on a top and wood on the sides metalized paint

one more

I will draw the cuircuit for these amplifiers give me some time and i will post the circuits fot both amplifiers.

I am currently working on an RIAA Phono extension for the power amplifier in the first post.
This Phono preamp will be based on an 45 year old RIAA Cuircuit from an Japanese REC Amplifier.
The original cuircuit was based on some old 2SAxxx and 2SCxxx transistors but i am modifying the cuitcuit to work with the nostalgic bc149c Gold pin low noise transisitors from National Semiconductor

Keep you posted

Well done on the passive preamp

I wish i had the materials to build such project housings
