Re: Brown Note D'Lite Questions
Wow what a change. It's really drastic. What is this doing inside the amp? I'm generally playing at pretty low volumes, with both the Volume and Master knobs not much higher than 2. I live in an apartment and would like my neighbors to not hate me. My basic googling suggests that this kind of switc...

Standby Switch on Chassis Ground
Since there are a lot of folks here using powder coated chassis... I noticed on recent build if the standby switch isn't making good contact with chassis that it becomes source of noise -- intermittent ticking sounds, can hear a little pop in noise floor when touched by human... Never heard the advi...

Re: Fuchs Dumble Clone
Reverb's policy is that the owner of the trademark has to request the listing be removed and show proof of ownership of said trademark. Ah. This is pretty consistent with modern internet times, IP violations are addressed on the backend via "takedown" requests. In the USA you own the rights to a tr...

Re: Fuchs Dumble Clone
Since nobody wants to ask Andy the obvious question here then I will. If it’s ok to slap Dumble’s name on an “obviously” not Dumble amp. Then I guess it would be fine for me or whoever to slap a Fuchs badge on an “obviously” not Fuchs amp and sell a few on reverb? Does Reverb even allow counterfeit...

Re: For anyone wanting to set the PI Trim pot
One of the mandates of the site's owner is that the history of the site will be preserved, so that's why the Sticky stands as it is, any warts and all. But being new here, I'm sure you didn't know that. Correct, I didn't know that. I joined in 2017 btw, same year as Phil. I was read-only before I j...

Re: For anyone wanting to set the PI Trim pot
I don't see where I was disrespectful to anyone. No personal attacks. No assigning merit based on post count or anything lame like that. If there's something I should apologize for please be specific. I've said my piece, if you high post count bros are comfortable with the clarity of this thread the...

Re: For anyone wanting to set the PI Trim pot
Otherwise, in my view, if he wanted the matched sides, he would have set these amps with the same 10K plates differential, present on the overdrive special But there's up to a 25k differential available via the trimpot... The SSS trimpot has 15k more adjustment range compared to the ODS. I'm more i...

Re: Fuchs Dumble Clone
Well to be fair, Jelle not exactly a layperson as he has made a business out of copying everything Dumble did down to a tee.(as Jelle pointed out)
Except the name of course. Steal all IP but never the name, that is the line. For some.

Re: For anyone wanting to set the PI Trim pot
I would love for you to tell me how mine are wrong... I love learning. Have a look at the Ampeg SVT schematic, the calibration procedure is there. Just telling people what's wrong, doesn't mean you're actually right. Maybe I'll just say you are wrong and move along. This thread is "wrong" simply fo...

Re: For anyone wanting to set the PI Trim pot
Dumble had a very specific outcome in mind for this trimpot and a very specific calibration procedure to go with it, and it's buried in this thread among other answers I don't think unpinning it is the right answer. Can you point to the specific procedure that goes to the designer's intent? Is that...

Re: For anyone wanting to set the PI Trim pot
This thread should be unpinned, that's great that everyone has come up with their own creative ways to trim the PI, their own opinions on the purpose of this calibration, but Dumble had a very specific outcome in mind for this trimpot and a very specific calibration procedure to go with it, and it's...
