Re: Reverb tanks and proximity to other components

Thank you for the informative info and pictures. OK, I might have some hope for having two of those 16.75" long reverb tanks fit at the bottom of this odd little amp. (I kinda like the "sound" of those MOD 3-spring, medium decay long tanks - (I'm actually "hearing" with my eyes, ha right). The inner...

Reverb tanks and proximity to other components

Hello, I'm in the middle of trying to outline an odd, shaped amp and wondering if there are any "gotcha's" or interference elements when it comes to spring reverb tanks and what the rules are with them in terms of proximity to primarily speakers and transformers. This amp in its odd shape only has a...

Re: custom size amp cover services

Thanks Chordball, I have been hearing good things about them and they kind off stole my attention from Tuki Covers. I like the Tuki website and the layouts to dimension your amp for a cover but, just hear better things about Studio Slips. After a 35 concert summer of gigs I'm on a 3-week break so, g...

Re: Now for some bright/treble cap snakeoil trials

Yep, was just talking about that to my engineering manager and the "component engineer" tonight, how it's a well-known fact that even moderately effective A/B testing needs to be done with A/B very close together in time or the comparison becomes moot and unreliable. Hell, I was just woodshedding my...

Re: Now for some bright/treble cap snakeoil trials

Hey nuke. I've never had a doubt about caps having varying characteristics. The place I work designs and manufacturers lifesaving equipment that is chock full of all kinds of electrical systems, and the engineers are very aware of the electrical characteristics of the various cap types and where in ...

Re: Now for some bright/treble cap snakeoil trials

My last build was a single channel 20 watt plexi that did have silver mica in both the bright and treble positions. It was bright alright but nothing a little Presence and Treble controls couldn't reign in. Now, lets see what the new caps do for the tone in this stereo 20 watt plexi. While its on th...

Re: Now for some bright/treble cap snakeoil trials

I hear ya fisherman,

If I was Leo Fender I'm certain we wouldn't be seeing any $11.00 caps in any position.

Of course, his amps all look more professional than mine. But we still have time!

Best,
Phil D.

Re: Now for some bright/treble cap snakeoil trials

Haaaa, I have a very, very embarrassing admission to make here - but I deserve whatever heckling I get, (because I know that none of you "ever" did anything like this. So started my stereo amp build with the full intention of going against the grain and use regular old MKT1813 polyesters for both th...

Re: Now for some bright/treble cap snakeoil trials

Thanks jbrrrr, I trust my own perceptions with what I will find. I was more curious what others have done and what their perceptions were of what they did and found. I might not hear anything no matter what I do, or, get hyper focused and hear things that aren't even there. And either of those is OK...

Re: Now for some bright/treble cap snakeoil trials

I should have left a disclaimer, I'm not looking to be fixed, or proselytized, or even educated. The post is simply asking, "what would you do"? I'll find what I find. Its just interesting to hear from others. When I say "snake oil", its just a play on the words that insinuate some kind of "special ...

Now for some bright/treble cap snakeoil trials

Hey there, OK, I allow myself one or two "snake-oil" components in my builds just because I can. This time it is $11.00 Sozo caps and some polystyrene caps from JustRadios. When I built this stereo amp I put all Vishay MKT1813 polyester films into the Bright and the Treble positions just for the fud...

Re: custom size amp cover services

Thats too bad jabguit. I like thier website and how clear and accessible it is to find the amp shape type and then input the measurements into the fields which I found where very understandable and well laid out. But what good is that if the fluff inside the cover starts to "Unfluff and fly" after a...

Re: NFB and waveform

Hello all and thanks for coming by, I can see that my misnomer was thinking that there was a zero V ground reference, as if there were an isolated + and an isolated - with a ground reference in there somewhere. I'm surprised I fell for that one for a while there, as there are only 2 terminals on a s...

NFB and waveform

Hi there, So, I was trying to explain to an associate "technologist" at work what NFB was in guitar amps and how it is captured and used, and what its resultant benefits are. During my explanation he asked a question I wasn't able to answer on the spot. He noticed that the + terminal on a speaker is...

Re: custom size amp cover services

Thanks, Xtian !!

That is perfect, shows angles for faceplate, speaker baffle incline, exact handle size and location, and the rest.

This is exactly what I'm looking for!

Thank you so much,
Best,
