Kenwood KA-9100 and TRIO KA-9300 comparo pictures

[kamagong]

Sharing pictures of these two fine specimens from the golden days of audio design..
Beautiful :yes:

if its alright, could somebody show nudies of their 600s?

 

[lha1992]

WOW! is all I can say about your KA-9300! That thing is very rare! Your 9100 also looks very nice too!

Congrats!

 

[Tower Boss]

Very nice and always in awe of the goodies that never made it to our shores! :thmbsp:

thank you lha1992 and TB..

The Heatsinks..
text lifted from TVK..

KA-9100
The heatsinks are forged in such a way that they form the rear 'feet' and much of the sides of the enclosure, and are an integral part of the construction.

KA-9300
The power transistors are mounted on oversized heatsinks - in fact, special attention has been taken to insure proper thermal distribution - the inner side of the heatsink has profiled ribs to compensate for lower ventilation with a larger area.

Thank you for sharing these with us. It's fun to see the big brothers to my little KA-3500.

That 9300 is a beast.:yes:

KA-9300 is the Japanese version of the Supreme Model 600, with a few minor changes here and there (most noticeably the two toroid transformers instead of the standard E/I core trannies of the US models).

Thank you for sharing these with us. It's fun to see the big brothers to my little KA-3500.

you are welcome sir

and last but not the least
The Transformers and Capacitors

KA-9100
The power amp sections are moved onto outboard mounted massive forged heatsinks, and the power supplies and transformers are centrally mounted. The power supply is massive, using two 12000uF low ESR electrolytics made by Nippon Chemicon, per channel - a total of 48000uF for both amps!

KA-9300
The power supply, appart from it's obvious dual mono configuration, deserves special merit. The roster of semiconductors becomes much more understandable once one considers that a single power supply has stored energy in two 18000uF capacitors at it's disposal, making the total a record breaking 72000uF in both power supplies (remember, this was designed in 1973!), something even most today's high-end amplifiers can only dream of. The preamp of course has separate power regulators. The power amp features DC and overcurrent protection (both electronically and via fuses

That is a great amp(9300)........is yours a multivoltage unit.....or 100v?
I am trying to hunt one of these down.....

thank you. its 100v, japanese domestic model. goodluck on your quest :yes:

Nice!

 

[denniswilson]

Beautiful !! I really enjoy looking at these pictures... And thanks so much for sharing !!

 

[nickrobotron]

I love looking at this thread. The 9100 looks so small.

 

[Trio]

And to think my vintage Trio, which is in very good condition, demonstrates such a modest begining heritage that has evolved to such a beast. It would be like puting a P38 next to an F15 fully decked out.

 

[TankPopper]

A fully recapd KA 9100 hooked up to a pair of ADS L1290 is one of the BEST systems i have ever heard.

 

[CohibaJoe]

NICE.....But Please Recap that KA-9300....

 

[JoshHendi]

How do they compare sonically? I love my 9100 and wonder how the 9300 compares?
