Quad 306
 

Hi, I would like to get some infos on this power amp. I didn't understand
well if it's a tube or solidstate amp? How many watts has? It's enough for a
medium room with 89db floorstanding speaker?
thank you

I have two 306s here at the moment.

The Quad 306 is a 50wpc solid state power amp from the 1980's to early
90's. It did not use the more common current dumping technology of the
larger 405 or 606 model but is still a very good little power amp none
the less. You should not worry about it driving speakers with 89db
efficiency as this is a very common rating. Used sensibly its ok.

The seller said it was of 1997. Could it be?

** I posted a schematic that clearly shows it IS a Current Dumper !!

Where does this ******** come from ??

** It is a VERY good little * Current Dumping * amplifier.



Borosteve.


** A close relation of " Borat " maybe ??

** The very last examples were made in 1997 - as a simple Google search
on the number will reveal.

Got no Google on your PC ????

Now that would be a real surprise to the Quad people - and especially the guy that wrote the service manual for the 306 :)....and
I quote" The amplifier uses a current dumping output circuit, a Quad invention ......"
And according to Ken Kesslers book on Quad, the 306 was made between 1985 and 1995 -all 25,000 of them.

No it was discontinued earlier than that as there was a range called 77
came out in about 1994.

I have two 306s here at the moment.

Which specific circuit features do you think prove that this amplifier is a
current dumping design?

That would be the lack of bias current in the output transistors,
the fact that the main output transistors feed the output through
an inductor while the low-power amp feeds it through a resistor,
and all the other gubbins you find in a current dumping amp.
