No, it should only affect the bass. There should be a drastic change so something isn't right.
-
The circuit is a 6 fold multiplier so limit the input to 100V (with a 5% error in the harmonic suppressor) and you are close enough. All Stax bias supplies would fall under the "close enough" realm. There is nothing regulated in any of the Stax amps except the SRM-300.
-
With a bit of glue they will fit just fine...
-
No, not really. I don't like doing it because it drifts a bit more but that's it.
-
The zener has to be 550V for 500V use and don't jumper that cap. The only thing that will do is connect the HV directly to ground. That isn't the best idea...
-
All of this is true and don't forget the small jumper marked B in the upper right hand corner. That needs to be connected. All in all this shows what a terrible idea it is to take over someone else's project.
-
Yup, do not power up that PSU. It will blow up quite horrifically...
-
Same as all other voltage multipliers. Extra parts to keep the circuit in inline but I'd prefer to have the extra transformer. Makes things a lot easier.
-
Just use a high ratio 230:12V and tap it off the secondaries of the stepup transformers. Then you can either put in a voltage doubler with a 115V back to back zener on the input or just run it directly like that.
-
I'm probably going to order one soon. It is roughly 330mm wide, 360mm deep and 100mm tall. Weight is about 8kg.
-
This is the the classic, we have this guy doing it that you've never heard of before so it has to be good. Let's see some specs and not even compare it to the Dynahi but just the pure bipolar. I also truly don't get why it isn't balanced. In this marketplace and at these prices, it has to be. Simple as that.
-
I like that one a lot!! I have a pile of these that I need to finish at some point as it is a really good amp. Any troubles with that feedback switch?
-
Couldn't have said it better...
-
I doubt they would be damaged but do a quick diode test on them. If they measure fine then they should be fine.
-
Yes.
-
Has to be the fets now that both channels are blown. I'm hesitant to use any part not sold by a proper distributor so no local shops even here in Iceland.
-
Could be but I doubt it. Has to be the resistors acting up.
-
A small 2*0-15 with the center secondary leads tied together does the same thing.
-
You can run either one assuming the PSU and transformer are up for it plus the heatsinks. Mine are all run at 400V because I don't see the point in going higher. With the 009 perhaps....??
-
You could put in large resistors to drop the voltage but the only sensible thing would be to get a new transformer. This isn't a project where you worry about 200$ or so...
-
It is 30VCT so 15-0-15V not 60VCT like you have.
-
Why do they have a Woo WES there?
-
Well there is that which is so absurd that it isn't even funny but no, their status as the community retards has be locked in place for a long time now.
-
That has been my experience. The carbon shines in the top end the more power you feed.
-
I agree that the 10M90 is the most likely culprit here. I would strip it out and clean the boards well. No clean flux does not apply at these voltages!!!
