from what I understand, the natural phenomena that can happen can be quite scary with mega volcanoes, giant meteors and such. Human life ain't very long at all compared to the life of the planet, so hopefully I'll get to dodge all the especially frightening ones until I croak and my remains reinhabit the earth as dust once again.

(to try to stay somewhat on topic... :lol:) Saw this on Gear Slutz. Thanks to (some dude--sorry forgot his nombre :oops: ) Tascam belt replacement doc., schematics, etc. are avail:

Dual topic, well it is 2012 after all :P heard mitochondria DNA evidence suggests humans almost got wiped out about 75,000 years ago by one of these cataclysmic events :shock:


Ah good so belts are still available, I should change mine.

cool. Trying to take it ez typing (have a bad tendonitis affected finger joint). Bought another old cheapo mxr and trying to suss it out see if there is anything easy I can do such as reworking layout a bit, etc. to increase performance(lower noise, etc.). Kind of funny, saw a really pristine example of the same (Yam PM430) that was sold on ebay for around $500. Was REALLy clean (apparently stored unused in back closet of studio) but a nuts price(IMO--if it was that great why was it not used?--one has to wonder, as in "a mixer sitting unused for years IN A STUDIO"). Mine is muddy sounding but assume would improve with new alu electros (so prob'ly not fair to assess sound w/out at least a recap). Interesting that my later M406 has better performance (less noise, more gain avail.)on paper and by ear (and judging a bit from looking at the PCB layout). Sometimes in various (recording related bbs) threads the old Yamahas seem to be bunched up into one but seems they shouldn't be all put into one basket.

Yeah would think any old gear that's been sitting around for years might need some caps changed, lotta classic receivers from the seventies require that as well.

take care of those digits!

was doing a bit more navel gazing (reading, toilet Buddha contemplation) about the supposedly special qualities of some of the older Yamaha mixers (quiet compared to newer Mackies, etc., very suited to certain sources such as gtr., keyboard) and what *I think* is going on is the ones in question are old unrecapped units, and the aging, degradation of all the alu electros had resulted (about 30-something years later) in a narrowing of the frequency response (this is in addition to the somewhat narrower normal response in a normally functioning unit) resulting in an enhanced suitability with certain sources due to a bit more low pass and high pass filtering. What seems to be the case in recording guitars in general (probably not in every single case) is that LPF (low-pass filter(ing) or a high cut) is used to cut unwanted information (frequencies which I think are harmonics from higher freq. distortion) from the sound and apparently also to help keep instruments separate so they aren't "clashing" within the same frequency range and achieve a (better defined?) overall mix. Moreover, the narrowing of the frequency response should lead to a perception of a less noisier mixer channel (but the Mackies, etc. should sound quieter as well if their frequency response was narrowed). (As an aside, I wonder if the apparently typical practice of LP filtering somehow models ear fatigue, that is, does the LPF help put on the recording what the listener hears after being exposed to loud volume--IME loud volume seemed to kill off the highs pretty quickly--and they would return after resting for a while (or at least until there is too much exposure leading to permanent tinnitis, i.e. ringing in the ear.)

*IF* I'm correct here, then it would seem to point to having an adjustable LPF in some form (on the mixer channel, some outboard EQ unit, or digital EQ) being more important than the not-really-well-defined special qualities of an old mixer (might be other distortions from the old mixer that enhance the sound, however). Also, if the alu electros in old pieces of gear had (relatively) worse response (compared to newer produced) and only get worse, this might help explain in part the preference some users exhibit for the older gear (vs. reissues, clones, recapped old gear) sometimes. Anyway, experimenting with "dumbing down" caps as suggested by R.G. Keen (if memory serves) adding series R and L might be worthwhile.

edit:

also interesting (a link to an article about feedback, different topologies and distortion and a summary) :
