The internet has plenty of bogus, erroneous and egregious stuff on it already.Originally Posted by mooreamps
Like bypassing a fixed biased gain stage ? Where did you get that from ?
Dude, seriously? Again with this stuff? I have seen tube datasheets that talk about using a diode to fixed bias a tube. Early tube circuits used BATTERIES to generate a fixed negative bias. Nothing is new under the sun.
You may have original ideas that are sellable. This is not one of them.

*sigh* You still don't know what that capacitor does, do you. Hint: It's not there for gain or frequency response purposes...
Are we talking about a diode with a snub cap on the cathode of a tube?
...I agree, and there's a subtle "likeness" between RDH and Blencoe's books, both in style, illustrations and context.
...and the Devil said: "...yes, but it's a DRY heat!"
Well, we can dream, can't we?
I know inside my preamps, it has no effect. Hint : "It's not there for gain or freq response". Really ? Well no sh*t....
A sweet dream where we are judged for the content of our amps and not the chip on our shoulder...
Ya, well, Chip your shoulder on this. I'm not giving him any more free material for his book.
Gary, are you trying to tell us that YOU invented bypassing the fixed bias gain stage? I see it in figure 12.5 in the RDH, so you must be one really old dude, since apparently they must also have taken it from you.
Education is what you're left with after you have forgotten what you have learned.
Considering that you have never actually published a schematic online, where am I supposed to be stealing this material from?
you read his mind.You are Merlin after all...
They did steal it from him. You see, he also invented a time machine, but he can't tell us about it due to non-disclosure agreements his employers made him sign. Besides, Merlin might make one of his own.

As I see the circuit in figure 12.5 ; is not the circuit I use.
The phrases "legend in his own mind" and "out standing in his field" leap to mind.
Never documenting anything means you can never be documented as wrong. That at least displays a kind of low cunning. Sad, but low.
I don't trust him....
...and all his stuff is posted free online, just like... oh, that's right, Gary doesn't post his stuff. Except for vindictive and snide remarks. Try posting something with a little bit of useful info or some humor in it and maybe you'll make some friends here!
There's lots of us who (usually) silently watch the goings on here to gain some useful insight, ideas and solutions to problems. I'm sorry Gary but I have yet to see anything you've posted that contributed to any of those.
... and thank you Merlin for the posted info and the book. Bring on number two (and three and...)
Yeah - I don't trust him either. I have to watch him all the time. Never know what he'll do. 8-)
Alright...... Since the other thead is titled Dual Rail Power supply, I'll upload my split rail HV supply ; with shunt filters.
.......so how did those backwards rectifiers work out for you?
OK. you got me on that one...........so how did those backwards rectifiers work out for you?
So, Gary, how does the output voltage stay balanced at 600V and 300V in the face of unbalanced loads on those outputs... ?
the plate rail carries the greater load. I've noticed they do track with respect to each other...
and by the way, this is not my circuit.. It come out of one of Kevin's books. All I did was just add my own refinements...

Is this really necessary?
You know very well the diode is there for shunting switching noise. I quoted that to you from Merlin's website the last time this was discussed. I know you read my quote, because you replied that there is no switching in your amps, because the signal level is too low. Fine. Some people use boost pedals. Some people like cascaded gain stages. They might need the shunt cap. You don't, fine, but accept that others might have different needs than you. Please stop making a fool out of yourself!
It seems like that about the gist of it.
But we don't know, since Gary won't publish his stroke of genious out of fear that someone might steal his idea. We know it's fixed bias, we know it doesn't derive bias from a voltage divider from B+ like fig. 12.5 in RDH4, and we know that Gary's furious with Merlin from stealing his idea when writing about using a diode for fixed bias....
Ok
But the question about the scope of your invention is a good one. Do you claim to have invented diode biasing? Bypassed diode biasing? It's really hard for all of us to avoid stealing your idea ahen we don't know exactly what it is...
What exactly is Mr. Moore's fabulous fixed bias?
The next obvious question is when you invented whatever you did invent. If I'm right in that your invention is diode biasing you deserve a lot of credit if you where the first to invent it. So when did you first mention it? When did you first implement it?
(I know, normally it doesn't count to have built something when it's not published. But I still think Gary deserves credit if he actually was a pioneer at this, evenif he was the only one to have actually seen it.)
No... I saw it used on another system. I liked the idea, so I used it as well. I had to tweek the circuit to keep the tone from getting too muddy..... In this video, it's a little over-tweeked.....
It's misleading...bypassing has no effect......
I first mentioned it on ValveJunior.com , and I think on Ampgarage...
YouTube - Model gm-5 ; 5 watt amp with Electronic Power Braking #2
OK, let me make it a little clearer. Where does the CT of the power transformer connect? It goes to no other symbol on the schematic.
By the way, I notice you are using solid state diodes in series with the rectifier tube. Isn't that redundant? Did you invent that too?
So, you're hacked at Merlin for "stealing" something that *you* swiped from elsewhere, then?
That doesn't exactly seem like rocket science to me.
You're Not Listening to Me... bypassing the diode has no effect...So, you're hacked at Merlin for "stealing" something that *you* swiped from elsewhere, then?
That doesn't exactly seem like rocket science to me.
No.
1. So why is it you're hacked at Merlin? Exactly? In English?
2. So is what you're misunderstood over the concept of *not* bypassing the diode?
Try using your words to explain. I have to Not Listen [sic] when you don't write anything down to Listen [sic] to.
Or would writing something down mean you take a position that can be evaluated as something other than mysterious vague references?
Inquiring minds want to know.
