My budget vintage setup
« on: November 02, 2012, 07:22:35 PM »
Recently i got myself some old kenwood bits, an amp, tuner and cassette deck. Have been doing some light restoration work, replacing dodgy components, cleaning.....


Amp: Kenwood ka-70 from 1980



Tuner: kenwood kt 413 from 1979




Cassette deck: kenwood kx-400 also from 1979

I have exactly the same amp, they are bullet proof!
I used to do some dj work in/just after school and used that to drive 2 15" base bins.never even sighed.
What speakers are you running?

Currently it is just driving my headphones. Am still looking for some speakers for it 

But yea, it does appear to be a pretty tough old thing. There were two blown diodes but one of them was right next to another diode that looks to have been replaced at some point in its life. So I assume the technician was a bit careless(judging buy is awful soldering) and broke the glass casing whilst removing the component next to it. It was working just fine even with the complete split diode

The only issues that remains is that only two of the 8 source indicators lamps are working. Have not got around to getting replacements yet

Nice! I used to have a KA-70. It was on permanent loan from a friend. Dig the effect of the source indicator lamps!  :thumbs:

Wow, Stig. Never new that still existed. Was my very first amp I owned. You have just brought back many, many fond memories of DIYing, building your own speakers, listening to vinyl, tapes and sharing girlfriends with my brother. :EGrin:

Very nice. Lighter fluid will take the remains of the sticker off the amp.

Or even Mr Min (the spray). Spray a little on the area, leave it for a couple of seconds, then use a soft tissue and remove the sticker remains. Use this on all my purchased cds when I want to remove the labels on the cd covers.

Thanks. Got most off but that residue remains, will give the mr min trick a try.

I also replaced all the belts in the cassette deck. The drive belt had reduced itself into a sticky mess and the rest were in pretty poor shape too. The tuner was mostly ok except for a blown bulb on the dial pointer and two leaky capacitors, have repaired all that now so it works great.

Just tried the mr min and worked a treat, no evidence left at all. Pitty I cant do much about the small scratches

I would just like to ask if this was a decent amp at the time or not. Sounds pretty good and appears well made

Another pic of the amp and tuner in action, just two of the source bulbs are working at the moment. I have ordered replacements so they should be here soon :)
