I build speakers not amps so please be kind.
One of my Kenwood L-07M monoblocks just died.
I bought them used and I've had them for about 20 years so I guess I can't complain.
They are [ or were] driving the tops in my Tri-amped home system.
Should I try and get a repair done of just buy a new stereo amp of similar specifications?
Any and all suggestions welcome but my budget is severely limited at the moment.
I've owned lots of amplifiers over the years but the old Kenwoods were the best sounding amps I have ever owned

Definitely worth getting them fixed, all the documentation for these is on Hi Fi Engine. You just need to find a good audio repair guy in Melbourne.
A new amp of similar specs will be hard to find and it definitely won't be as well built. Might only cost a couple of hundred to fix, especially if the other one is working for comparison checks.

Any recommendations? I'm in Geelong and there is nobody here willing to even look at them. Real technicians seem to be few and far between.
If you haven’t already, look up ‘restorer John’ on ASR. I think he’s very familiar with these (down under) and could probably make some recommendations.
OK Many thinks and it seems he may still be active.
Made a post there and hopefully I get an answer, from him or someone else savvy with these amps

In the meantime I'll need an amp to tide me over; something like a Rotel 1070 would do.
Agreed
I signed up and a member has just bumped the thread on my behalf.
I may have to sell a kidney to get them repaired tho.

Hi Ted; what were the symptoms? Maybe it's something potentially minor a kind Melb member can have a look at. Or did it smoke up?
Hey Stuey
The volume started to fade in and out and then went very loud/very soft and before I could get up off the couch to kill the power the little red power light went out and no sound at all
No majik blue smoke.

No majik blue smoke.
Also no high pitched and rising audio scream.
I'm not going to open the case up just yet, I need to organise some good lighting and find the better camera

You are in a good position, as you have a working sample. Download the service manual, print out the sides of the schematics and combine them to a large readable one. Repair guys are lazy, some don't even start without a well readable schematic.
With a working sample for reverence and a clear schematic, such a repair should be quite easy. That does not mean cheap.
Maybe use the time to fix them and try something new, like a small D-amp. I recently got an AYIMA A07 (the basic version) for 45$US. Pair it with some power supply you have flyin around and just be surprised... I know, old dogs don't like to learn new tricks, but these sound very nice, really.

When I bought these the seller did provide such, thanx for mentioning it and I'll try and find them. I do have a cheap chip-amp kit here; two sets of the Jaycar amp; maybe I should actually try and build a couple of small units but the speakers do need a bit of oomph to really sing and I'm not sure 50 watts is enough.
Link to AYIMA amp. Oomph depends on voltage. It only need a single DC source from 24-48 Volt. I use 36 Volt 7A, which should give clean 2x 100W into 4 Ohm.

I use one of these, build into a aluminum case. They are surprisingly good and work with all D-chip amps I tried. 3116, 7498e and 3255. No noise and just a little warm after hours of 2x15 Watt (burning in subwoofer chassis)
