The background looks familiar - I think there's someone on site who might be able to answer your question!

Its 2 pictures that looks very much like Dillen's work.

He might have the answers to this one.

Yes, that looks like one I sold recently:

together with the B&O/Peerless Type M speakers


Any particular specs, you are thinking of ?

Martin thank you for the info!

What is the power output of Dirigent?

Alexey

Originally, the Dirigent had ECL86 valves in the output stage.
Very often, EL84 are found mounted instead which in my opinion
is a very legal and suitable substitute.
Both valves have about the same power rating, around 4-4½ Watts
so about that would be the rating per channel.
Worth noting that these are "real" watts - not those modern
cheap japanese watts that we often see on computer speakers, car stereos etc.
And the sound... just wonderful.

Not very nicely put by me, I realize. I was not intending to offend the
japanese but that was the only way I could think of to explain it and the
tendency does seem to come from the east.

In the 50's, an 8W amplifier was used for the commentator PA at a large football
stadium in Copenhagen.
Today, people have 20-40W or more in their car and 400W at their computer table...
Open up a 200W PC amplifier/speaker and look at the tiny transformer and thin leads
and you'll know what I refer to.
Speaker efficiency is an important factor, I know, but surely those cannot be the
same type of watts.

Martin, were there more powerful B&O valve amps which can match to M-100 speakers?

Yes, the models with push-pull output stages will have more power, at least theoretically.
The HiFi amplifier 608 (often referred to as Beolab 608) springs to mind, that's
only a an amplifier, no tuner.
Some of the later Grand Prix models and I believe also the Master Deluxe Present models also
have push-pull output stages, these are complete receivers, tuner and amplifiers.
The Master Deluxe Present and some of the Grand Prix models have built-in speakers.

The Beovox M-100 are heavy speakers to drive. I am not sure they would be a good match for vintage
valve amplfiers unless really powerful (of which B&O didn't produce much, apart from the BOFA cinema equipment).
The impedance will be off too. Typical impedance for valve speakers are 3-4 ohms.
