I could set up a temp password and it could be dropped into the website via ftp. I just wanna see 10mb of carver but I'm willing to share. Also something like Art Split Pro could be used to break the pdf pie into slices, though I have never used it. My point is that there are options to breaking it down. 🙂

Chris,
Not that familiar with triac regulation circuit. My query is regarding a component in the gate circuit of the triac. It is labeled DC1 and looks like some sort of diode(same dimensions as a 1N4148), but measures open circuit. The supply attempts to work, but makes speakers pop intermittently and pulses off and on until it finally settles down to work. Also seems noisy with a no signal condition.
Thanks,
Kevin

Hi wellsvid,
Yup, it's a 40V diac.
Use a 10K resistor or better and check with a meter and a power supply if you want. It should suddenly begin to conduct. Note the voltage, reverse it and test again. These two readings must be the same or you will have misfiring problems.
Bad filter caps may also cause this condition. The lower two tiers will be suspect. This sounds more like your problem.

Many Thanks for the manual pjaneiro.
Certainly more hope of sorting out the drama's with this amp now.
Much appreciated, Andrew

Guys, just be aware that there is on the order of +/- 125 VDC in those things. The supplies do not discharge quickly so be careful please.
Read the manual at least twice before opening this unit up.

Hi, I would be interested in this schematic too. But what I really need is to know the capacitor value and spec for the cap that connects to the speaker terminations. It is the one that connects in series to a resistor at the speaker termination.
I believe that it is a .47uf 630V cap but I can't read the physical cap real well.
Thanks
Phil

Hi Guys,
It's a 10 MB file, which will bounce off most email accounts. I thought Shawn was setting up a download for this on his server.
Poor pjaneiro has gone crazy sending this thing so far.

I am getting bounce backs like crazy....if ANYONE has a site where i could upload the file i would do it gladly,i also have the schematics for the pm-1200...so just give me the site and i will post it there...

I'm trying to set up the ftp again. I'm having problems with the interface to the provider, been like this from the start.
Perhaps someone else can beat me to it? I need a new hosting package or some real computer skills?
...but I'm working on it...

Does anyone know the coupling capacitor value and spec? The one located nearest to the speaker terminations.
thanks
Phil
thanks

Hi Phil,
C118 (output 1) is directly across the speaker terminals. It is 0.1uF, 200V film. I'd get one rated for current spikes.

It is here the PM1.5
Finally it is up and I'll keep it up until I get in trouble.
