Re: Sony STR-K750P STR-DE495P protect mode yay!

New STK350-230 from MCM fixed the center channel, but the volume still seems low, even at max volume it's like half the output of my [URL="http://www.parts-express.com/pyle-pca3-mini-stereo-power-amplifier--310-2002"]PCA3[/URL] or even the [URL="http://www.parts-express.com/lepai-lp-2020a-tripath-class-t-hi-fi-audio-mini-amplifier-with-power-supply--310-300"]LP-2020A+[/URL]. I replaced the 1.2ohm resistor with a 1ohm and can't tell the difference. It is loud and clean, but not like "WOW THAT'S 100W PER CHANNEL!!"...

Ok, update.

Replaced the blown 1ohm with a 1.2ohm because it was $2 for 25 and they only had that and 2 total 1ohm in stock, so if I blew up a 1.2ohm it wouldn't be bad since I have 24 more.

So now I've got music on all four channels except center, which I desoldered both +/- 53v inputs. I'll be getting a new STK350-230 soon, I don't want to take it apart again to fiddle with it until I get the new one.

The next problem is the volume, even at max it's probably only about half of what it could...

I'm having the protect mode problem with a sony receiver, but with different results after testing. I have a schematic and a fluke 179, so I'm kinda half way there! [url]http://www.electro-tech-online.com/attachments/str-k750p_de495p-282-29-pdf.34261/[/url]

So I checked solder connections, redid a few, didn't look bad at all, that didn't fix it. Started checking voltages, front left and right and surround L/R ICs have the correct +/-53v input, (forgot to check dc offset), center channel measured behind the output safety relay (because it was easier to get to, but it's after the chips...

Just saying hi, thanks for having me.
