Mystery B&O (1978 should give you a hint)

6 replies

Oh yes!

I remember lusting after this at the dealer in 1978.

I ended up buying a BeoMaster 3400 Quad - still with me today, BeoGram3400 Quad, and 2 Beovox 5702's.

This beast was $1400 then - a chunk in anyone's dictionary. 2x 105WRMS @ 8 ohms.

Can anyone guess what it is?

And if anyone has one for sale, I'm very interested!

Drool, drool....

Output amplifier capacitors - 15,000uF 63V - now where can you find an amp with brutes like this in today's mini-micro market?

And a fat toroidal transformer!!!

Size is EVERYTHING!

I don't think this was a B & O concept, however it does look good! Deep down in memory lane there sits a brand that used design like this and that is the Japanese firm of Nakamichi. Famous for it's high-end cassette tape players (dragon) and also some very good omaps and receivers.

That is exactly what it is.

A Nakamichi 730.

I had one. My actual unit is pictured at the bottom of

You guys are good!

That was at the height of B&O's technical expertise and reliability, and other firms were clamouring to emulate them.

Nak's efforts were the best advertisement for B&O.

Jaff, Before I bought my Niles 275, I tried to get my hands on a used Nakamichi PA-7. Sadly it never happened...

@Menahem, talk about toroids and caps!! (PA-7)
