I love 317's. Awesome chip. I always have a few laying around. They simplify power supplies so much.
A great little tool you may want to bookmark:
Saves having to think.
^ self biasing setup?
Have you ever seen this:
I've always meant to try it on something. That's probably overkill though. This would probably do for the sort of shit we play with:
or even without the zeners.
Question: What was ghetto ****** doing in Hong Kong?
but they can use rosewood and ebony.
they are choosing not to.
China just wants to sell more Bugera. Once they realised we all know about the plastic clips, they bant our forums
I know this technically the wrong forum for this, however I know that most of the really knowledgeable guys are here.
I am in the process of breaking in a new set of WGS Rebel 30's, and am wondering if the wattage on an Amplifier (or a PA) is actually the amount of wattage it pulls from the Walls. I am asking because I want to set it up and run for a long period of time, but don't want destroy my electric bill.
Well yes. But oversizing isn't the entire story. Give the exact same winding a m4 will be half the size and X percent more efficient with -Y degrees of heat loss compared to m19.
where x and y are numbers from wikipedia.
not really important really though. Just doing some reading. There's effectively quite a bit more weight reduction possible though without ditching transformers.
ya that's the gist of what I got as well.
edcor only uses m6. I seem to remember an onetics spec sheet saying he used m4 for his stuff but I can't find it.
however, if i'm understanding this stuff right...there doesn't appear to be any sort of mojo in terms of power transformer building. An m4 will always be more efficient then an m27.
ya I was wondering because I was reading Aiken's notes on transformers and how core steel grade corresponds to size and therefore bigger isn't always better.
heyboer apparently uses like m27 on their "vintage" lines and m19 on their other stuff.
The heyboer I'm using in Dom's amp is like 2.5 times the size of my onetics transformer. and now I know why.
R19 should read 390R
Well, as I said it's been running fine with the current cathode resistor - but I'm running JJ's. I don't have any shit EL84's to try.
100 ohm screen resistors. What plate resistors? You didn't mean to say that did you?
The screen current is like 0.5 mA so we can just ignore that
It's an 18W Marshall. So A/B EL84 amp.
rawrwuh? it's an 18 watter. it's not class A.
can't tell if joking?!
bias has very little to do with the output wattage.
Thought I'd better recheck the biasing on the JD amp before I pack it.
I am using a 390 ohm cathode resistor.
plate voltage = 390V
voltage across the cathode resistor = 16V So 41mA for both tubes.
That becomes 8W per tube. Seems a tad high for EL84's wouldn't you think? Looks like I may have to go for a drive and pick up some bigger 5W resistors. It sounds good though and there's no redplating.
i think pregnancy should be controlled by lottery.
sterilize everyone unless they win the lottery.

Last time I flew I got upgraded to first class when I missed a flight due to a delay. Best flight ever. Its amazing how big a difference it makes when they start serving drinks on the runway.
This looks promising. I wonder what shipping would be worth. It'd be light so probably not a lot.
I may just have to stick with the guy I have been using. His sheets of fibreglass are 12" x 7" for $10. Starting to sound not so bad afterall.
No, see, you forget that we have the most guns. If we pull a Zimbabwe the whole system falls apart and we take over. Hitting the reset button on the world economy is a way of circumventing NATO and the UN. It's a bold move but we'd probably come out on top if push came to shove. China has a bigger army but we've got more nukes.
This is the equivalent of kicking the monopoly board over and punching people until they agree you've won. I feel like that's a policy America could really embrace and excel at.
That idiot is still arguing. Some people just don't know when to quit.
You say he's not just a troll al? He's like this in EG too?
Thats total bull.
My 2x12 sounds good. My 4x12 sounds way better. Same amp. So my 4x12 is not needed ???cant get the same sound from the 2x12.
i once got kicked out of the club but i'm so cool and rebellious they let me back in
