AE EP#35 Hornyphon hifi sound project 6391

I bought some guys electronic stuff off ebay and this was amp was part of that.
in this you see some basic cleaning and me failing in installing a new backlight to the VU-meters.

This unit is the Hornyphon hifi sound project 6391. It was also known as the Philips SX6391 or the DUX 6391.

nothing too special but I am now using this as my primary PC amp.

A big thanks to for some basic info on this!

Also some pics for the ride:

Live long and Prosper!

sk7cas mobile electronic lab — check it out!

sk7ca made up a great portable electronics lab (with /A LOT/ of arduino-stuff) in an old laptop case and a small road case. I am so thrilled about this, that I asked him if I could feature his build on my blog and here it is:

He found some really good use for these old computers that no-one seems to throw away but isn’t using it either. Note the VME-bus connectors used to interface the BB to the plugs – really nice.

In this case is all you would need to have some fun on the road – a ton of chips, a small MM and a bunch of wires!

Didn’t I promise a load of Arduino add-ons? Just a lot of bits of hardware that make prototyping fast and clean – just like you would want it on a portable lab.

Be sure to not only check out sk7cas video on this but also his youtube channel! There is a lot of stuff ranging from amiga music to water plasma in a jar….

More pics right here.

For me this is a definite /want/ – this old laptop on my shelf seems like it could use some modding …..:)

Luxury Junk

I just couldn’t resist bidding on some ebay deal where a guy sold his cellar of HIFI-electronics.
There was /much/ more than shown here. This are the parts, I probably gonna use in some way.

JVC GR-SX9 Video Camera

Some very old (1991) Camcorder, I gotta look into connecting it do the pc to finally get some descent webcam input.

AIWA AD1250 Stereo Cassette Deck

This is some very solid case, it will probably house a synth or a mixer in the future.

Blaupunkt 60W 3 Ohm Car Speakers

Just that, they’ll go into a boom-box.

Premier CB 2000 Citizen Broadcast Radio

This one is interesting because i want to get a ham license in the near future. It does not work atm but I’m on it. the amp on top is known as a “Brenner” (afterburner) or “Oma” (grandmother) here in austria. using such an HF-amp with CB is strictly forbidden. (4W only, 12W with SSB)

Yeah this one needs some serious cleaning and testing but it could very well become a good mate in the future.
