    You know, that's funny because i was just about to come and declare that whatever it is, it sounds too good to worry about, but of course you're right. I've spent the day listening it, and it's just amazing how nice it sounds after the recapping. I mean, i can appreciate the "better" systems, but it just has this nice and warm

    [quote user="yachadm"]Check those carbon resistors which are in the Power supply circuit, especially those whose function is to drop voltage - you'll probably find a couple out of spec. Did you do a voltage check across the power cap, as before? I'd be interested to see the difference in measurement results.[/quote] Well, in fact they

    Thanks Mika, yes, for it's age it's pretty pristine, just old but no structural deterioration, not one bit of rust. Same for the speaker elements, not the smallest hole. Except for the fuse holders that i changed before anything else, it was just a question of lubricating and fixing the component problems. It would indeed look like it has spent

    The next chapter ; i thought to report on how it went, so that maybe one day it can help someone else, in any way, as my good Karma payback. So, got the recap kit (thanks Martin !), nicely documented, and attacked the job. Luckily this is old circuitry we're talking about, because my soldering equipment isn't what you would call the most advanced

    Magnificent. [quote user="yachadm"]A good (used) Fluke DMM and an ESR meter is a very comprehensive toolbox for troubleshooting electronics. Menahem[/quote] Thanks Menahem, but i saw the Fluke's while browsing for meters on eBay just now. I could never afford one, not for the use i would have for it. Not today anyway. If i would really

    Hey, thanks Mika for your efforts I actually had the manual of the meter downloaded, after having read something of the sort while googleing yesterday about AC measuring. But i wasn't able to decipher this in the manual, it said being able to read it. So you saw it directly on the schematics ? Wow. Ok. I read about that method of a small cap in

    [quote user="tournedos"]Try measuring some known pure AC signal, like the voltage over the dial light bulbs (should show 6-7 volts).[/quote] Well, the curious thing is, i just tried and it's a steady 6VAC, which on the other hand should prove that it measures just fine ? What on earth is going on here ? Sebastian

    [quote user="yachadm"]Can you get a better multimeter to make sure that you get the right readings?[/quote] Oh, so it could be the multimeter, yeah i hadn't really thought of that. It's true that it's an el cheapo and has had a few years of service. This said, i couldn't really justify to get a top-of-the-line one, but i'll

    Yeah, no, there's no heating in particular. To tell you, i didn't really notice anything unusual before this ripple measuring started. Here are the latest measures : - cap 514 : AC = 56.4V / DC = 25.8V - power cap (1000uF) : AC = 65V / DC = 29.7V And here's a photo of the method used to measure the value, maybe you could confirm if it's
