Wow, it's been fun for a minute, but now Mr AmpChaser you're starting to call names and talk bad / insult respected people you don't know; sounds like running out of factual & logic arguments and crossing the line.
Why all that secrecy and bad words? What's the point in posting on public forums for that? I don't get it, like so many others here it seems.
Please, you haven't answered my simple question VS John Suhr' words & experience on that very matter; I'd really like to know.
First of all, I didn’t insult anyone. What I take issue with is people mocking what I’m saying without taking the time to actually check the information I’ve gathered. That kind of reaction feels like an attempt to discredit my research, and I don’t appreciate it. If someone disagrees, that’s fine—but at least look into it or ask questions first. Mocking without verifying is simply disrespectful.
John Suhr stated that the preamp was stock and that there were no signs of the amp having been modified, mainly because most of the solder joints on the preamp board appeared intact. However, years later, when the amp came into Dave’s hands, he publicly released detailed photos. Those images are still available online, and they tell a different story.
Looking at those photos, it’s clear that many of the original components have been replaced multiple times. The mustard capacitors are gone, the filtering has been changed to non-stock values, and there is visible evidence of repeated work on the board. Anyone familiar with Marshall Plexis can see that this amp is not stock. The solder joints are not untouched—quite the opposite. Multiple components have been resoldered on the same turrets over time, and there are even visible flux residues across the board.
on top ed's amp on the bottom serial 12309 8 serials after ed's amp... look at the differences; it's huge...
The filtering is probably 16+16µF or 8+8µF on the top board, whereas on the bottom (stock) it’s 32+32µF. That’s just one example.
The Cherry Drop capacitors—the red caps on the top—were used a lot by José, and I’m sure Dave is aware of that. In the bottom picture, you can see mustard caps instead.
Now, let’s look at the large square ceramic capacitors, which are the treble cap and the mixer cap. These aren’t stock either—they’ve been replaced with red capacitors of unknown value.
Also, look at the blue coupling capacitor: it’s not stock. On top of that, it doesn’t even connect to the turret—it connects directly to the 100k plate resistor before reaching the turret.
I could go on and on about the issues with the top amp, which was Ed’s amp before Dave brought it back to stock.
