ffs, something really strange going on with Windows 8 here, every time I

Hmm, seems to work if I delete the original text.
Anyway, the limiter might actually be doing its job and preventing the whole
thing blowing up, you don't want to disable it.

This has been seen on other groups. The suspected mechanism is that

Thanks, Jon.
My Windows 8 has been buggy from the start, Live Mail particularly so,
always complaining it can't back up the database because it is in use by
something else (???)
Live Mail is what I use to post on Usenet - I guess its teething problems.
You know the only improvement I can see that Windows 8 has over XP is that
it boots up a lot quicker - seems to keep some kind of "snapshot" on file
somewhere, otherwise it seems to do exactly the same job I ask of it, but
with a whole load of bugs, and I can't find things any more.
Cheers,
Gareth.

I have seen the following problems occuring on StagePas 300 :
>People change cables w. "standard issue 10m cables, 6,3mm Jack ends" because they need longer cables. This won't ever work; Most industry standard cables having 6.3mm jacks are meant for guitars and other relevant instruments,Conductors inside are thin and coaxial having enormous capacitance and very large resistance.
You need to order your technician or build yourself a pair of REAL Loudspeaker (twin-lead and sufficient thickness for 150W power handling) cables having mono 6,3mm jacks end to end. You won't burn your amp that way.
also -
I have noticed a problem w. my set that showed after 15 mins of operation the following problem:
Sound cut off, replaced with low frequency hum (thus amplifier is still active), Limiter led (red on bar graph) stuck ON, Turning it off and after a few minutes back on solves the problem.
That problem was traced down to an 7915 voltage stabilizer on the main preamp/psu board, having an output of -8V instead of -15 on normal operation and after 15 minutes that voltage fell to 0 volts. Replacing the 7915 with another fixes the problem (solid -15V on output). My Stagepas 300 has an 7915 with plastic casing (too large heat resistanse to heatsink, I guess, and a semiconductor fatigue resulted to that problem). It looks that using a metallic 7915 is possible as the heatsink is electrically isolated from the rest of the circuit on my revision, if in doubt use some mica - plastic ring isolator there.

Mak,
Did you replace the 7915 chip yourself or did you have it done in a shop. I don't trust myself to make this repair but the cutting out problem has made the Yamaha unit totally unreliable so I really need to try it. Any tips would be greatly appreciated.
Thanks J
