Hello,

About eight years ago, my father gave me a Nikko amplifier, and now I have
become curious what kind of thing it actually is. I have made some pictures
of it so I hope one can see all relevant things:

So, does anyone know something about it? How old could it be, how much power
would it have? Is it any good or would any 10,- amplifier on eBay be
better?

And do any devices exist for the "Switched" and "Unswitched" sockets? They
look like English or American ones, but being an European amplifier it puts
220V on them.

Thanks in advance,

Daan.

This goes back to the worst old days of solid state. It has driver
transformers, and a performance that only its mother could love.

Keep this one for the memories, and buy yourself something - anything
- on ebay. It will be better.

Yeah, I was thinking the same thing: "Two xformers that look like output
xformers. I see no valves. What's going on? Surely not...?!".

I bet the transistors are germanium too.

My first vac job was testing out the very first Mullard (there's a name to
remember) n-p-n germanium transistors for the Ferranti Argus computer core
store memory drivers.

Thermal runaway is just the first thing that comes to mind.

Talking of germanium transistors - how about the Braun T1000 portable -
hundreds of the things. Mine still works - touch wood!

Fear not. Most of the 'bad' Ge transistors are probably long-dead. The ones
that have survived this long are the cast-iron ones. ;-)

Slainte,

I don't think anyone was suggesting it was impossible.

So how far along the bottom of the bathtub curve do you reckon it
might be? Cruising gently, or about to strike the plug hole?
