Guess the receiver!

[Dr.Turner]

Output transistors. Find out the wattage!

 

[Fredrik 1977]

hmm well that depends on the railvoltage.
i´d say that receiver is rated at aprox 10-15wpc

if u send me the servicemanual i can have a look at the voltage im not gonna look at the first page

hmm back mounted outputs?

 

[Dr.Turner]

yes, back mounted, protected with a black grill, Sansui AU-777a style...

 

[just dave]

Samsung? Hitachi?

 

[Dr.Turner]

Nope.

Another hint...

 

[Nashou66]

Harmon Kardon 330A,B or C? Or some other HK model.

They used the 2SD154 transistors.

[Dr.Turner]

You are close, Nash.
Even though the 330a/b use the 2SC1061 (or 2SC1107) TO220 internal outputs and not TO66 2SC154 external...

Well done anyway!

 

[f0427ea]

Fisher somewhere in the 200 series from early 70's

 

[f0427ea]

Or Sears /Fisher 143.xxx (edit not fishers no wood sides like pioneers and lafayettes)

 

[Dr.Turner]

No, not a Fisher.
Nash was close

 

[Fredrik 1977]

HK two hundred? or two ten?

 

[sax6]

Cap coupled output, single rail B+... Realistic....? Oh, wait... maybe Sony STR xxxx BOTL ?

 

[Dr.Turner]

Not a Sony.
Not, strictly, an HK.

 

[Nashou66]

Then I guess the plain jane 300 or also advertised as the SR-330

But there was a 330 too maybe that one?

 

[Dr.Turner]

Nash you were closer with your first reply.
Hints are here on AK.

 

[Dr.Turner]

Beautiful tuning knob.
Also found on the Wharfedale Linton/Denton receivers...ouch...I've said too much...

 

[Rolf Zetterberg]

HK Three Thirty?

 

[Nashou66]

HK Three Thirty?

Yeah the Three Thirty is also known as the "330" . Lets see what the Dr says

Nashou

 

[Fredrik 1977]

Wharman Klinton
harman with linton knob? where they involved in some way? i had a linton receiver ones.

 

[Dr.Turner]

It's not an HK. A strict relative.
There's something behind the scene to be investigated!

In the meanwhile a nice nightshot listening to stereo FM...
