Re: Music Man Power Supply [was Re: #102 died yesterday :( how,why]
I’d have to check the accuracy of my LTSpice EF86 models I use again. Last time I checked the curves were pretty much spot on the curves in the Philips datasheet. I hold the Ayumi models in high regard. Usually I’m not more than 5 to 10% max off when comparing sims to real life. I think the 240k an...

Re: Tweaking My 102 Amp: A Massive Resistor Makeover
Now, how close do you think you could get to this amp with resistors that are still being made?

And different gains. More Rp = more gain.martin manning wrote: ↑Wed Aug 28, 2019 4:29 amHarmonic complexity, I think. Each of those plate loads, with its unique cathode resistor value, produces different distortion content HD2, HD3, HD4, etc.

Re: Tweaking My 102 Amp: A Massive Resistor Makeover
The snob in me, back in the day, would have probably scoffed at what I’m about to say, but how about if most of the “tweaking” and customization Dumble did for his clients was selecting different parts to use in each build? I’ve come to think there’s definitely something to this. Remember the comme...

Re: Anybody know what this is...?
The board with the metal heat sinks on the 3 main Transistors looks like a driver board for the outputs of a solid state amp for sure! My bet now that those are out of one of Fenders SS. super reverb model amps as they sold the most from what I recall. Would the inductor be associated with the "Sty...
