Agree, these were good amps. Most of the Kenwood gear of the early 1990s were built like tanks.

Even though its fun to make your old equipment do a swan dive into the dumpster, I try to place it in as the next guy who comes along may appreciate that.

Good to know you like to see amplifier repairs!

The Kenwood xx10 series of 1989 was one of their best. Almost all of the components were very well-built and lasted a long time. The KX-9010 was the best Cassette Deck in its price range back then and the KX-5010 was probably the best 2-head deck ever made. My KX-3010 lasted for over 20 years without any necessary repairs or maintenance. Too bad people just throw stuff away like that.

Excellent work. Looks really well built

Good Job! Another piece of equipment saved from an horrible end. My Aiwa XA-007 has also both tone defeat and source direct buttons. I don't know if in your Kenwood is the same, but in my Aiwa the tone defeat button only bypass the Bass and Treble controls. Instead, the Source Direct button bypass all the control knobs and switches (balance, loudness, etc), having the shortest possible lenght in the signal path. And in this second case the improvment in audio quality is very audible. Keep up the good work.

I do not have my kenwood ka-3020se no more the left channel started going so sold it for £25 to someone like you who fix things.

Only use contact cleaners specifically designed for electronics. I use Kontakt Chemie Tuner 600. Never use "household alternatives" such as WD40. Some may say those work, but in reality they don't work for long. Either they leave a residue on the contacts that even more dirt can stick to, or they corrode the contacts. Either way, they will make the problem even worse.

Excellent job, appreciate you sir . Like your videos. Thank you.

its so nice ur keeping those vintage units out of the land fill...LOL

The later or higher-in-the-range KA 5020 model I have is a different beast inside, as far as controls and switches are concerned. The Input Selector has become very vague through use in the time I've had it, with problems in selecting both channels and also 'extends' past the marked points of choice at either extreme. Instead of a rotary selector inside, it has a strange 'ribbon-like' set-up that drives the switching mechanism to select the channels. Apart from a little jiggling of said input selector, it works well enough and is an excellent piece of stereo hardware.

ive got a ka5020, had it a number of years, its in use every day as the pc is connected to it, so far all that has ever gone wrong with it was a scratchy input selector, easy fix. had a marantz pm44se before that, the kenwood is far better, as the marantz i found bass light in comparison. some of these older kenwood amps are probably better than people think they are.

I think the source button is there for adding an eq to the system. Toggling between source and source direct would defeat the eq.

There are no dedicated connections for an equalizer on this amplifier. You would have to connect an equalizer into one of the tape monitor loops, in which case the source / source direct positions wouldn't make a difference.

Yes, you can just spray contact cleaner into the openings of the switch. No need to remove anything.

Back in the early 80s, I was told that Kenwood audio equipment was not that good. I went with pioneer and also had some of realistics high end recievers, which were their top of the line. I still have and use daily my pioneer equipment from the early 80s.

@@DrCassette Übrigens, ich hatte dir doch mal von meinem Knitterproblem mit mehreren der Technics Direct Drive Kassettendecks (BX 606, 707, etc...) erzählt. Daraufhin hast du gesagt, dass du dir so ein Deck evtl. auch mal zulegen wolltest, dich dieses Problem aber davor abhält. Mittlerweile habe ich herausgefunden, dass mit der Zeit einfach nur die Zugkraft des Aufwickeldorns höher geworden ist, wodurch dann bei dünnerem Band am Anfang, wo am stärksten gezogen wird, dieses am Capstan zur Seite wegrutscht und geknittert wird. Laut Service Manual von Technics kann der Aufwickelzug durch das tauschen eines Bauteils (Zenerdiode) geändert werden, alternativ kann man natürlich auch das Laufwerk etwas schwergängier machen, was dann aber mehr Last für den Motor bedeuten würde und sicher nicht die beste Lösung ist. Manche Leute hatten zudem noch das Problem, dass sich ein bestimmtes Zahnrad durch kleine Risse auf seiner Achse löst, bei mir ist es zwar einmal heruntergerutscht, allerdings hält es wieder, seitdem ich dieses wieder in seine Position gebracht habe - nun seit mehreren Monaten. Und für den worst-case gibt es Ersatz und diese Laufwerke sind im Vergleich zu vielen anderen sehr reparaturfreundlich. Gerade die Single Capstan Decks dieser Reihe sind sonst sehr pflegeleicht und empfehlenswert, wenn man nach einem günstigen quartzgesteuertem Direktantriebler sucht, dazu hat man noch einen Bias-Regler an der Front und Hinterbandkontrolle. Ich hoffe, ich habe dich mit dem halben Aufsatz hier nicht vom Lesen abgeschreckt und es wäre natürlich interessant, wenn du bei der Gelegenheit, ein solches Deck günstig zu bekommen, zuschlägst und dir eine Meinung zu diesen bildest.
