Hey guys, Finding too much Sag as I was told it's referred to as such, yet I've been calling having too much boominess in the bottom end, with this 5E3...i've got with the kit .1uF orange Drops and was sent these little .022uF capacitor to replace the one on the bright volume from V1 pin 6... to reduce it...My first question is if a cap is for stored energy then release it, and store again..how can this little guy do the same job as something so much larger than the Orange drop ?? 2nd, is there a + or - on these as there are in the orange drops..
I guess now a 3rd question....can all the .1uF caps be replaced these little .022uF caps and have as sweet sounding amp without the sag it has now ?? I don't think Sag is the right word....but thats how my mind seems to be real saggy.. :)

I iterated caps on my 5E3 until I found a combination I liked. That combination was 0.022uf for all of the coupling caps for me. It will tighten up the blaaaaaaaaaaaaaaaaaaaaaat you are calling sag. Purists will claim you will be taking the 5e3 outta the 5e3. This may be true, but I prefer it my way.
Nobody that played my amp at rehearsal last night would claim that it lacked bottom end or touch dynamics.

Thanks Commodore: so in other words, these lil white guys isn't any difference than the bigger caps....Are they polarity sensitive ??

Polarity doesn't matter on the coupling caps. Those are Mallory 150s, they will work just fine. And yes the .022uf Mallory is much smaller than the .1 orange drop.

Brain fart there Commodore thinking the coupling caps were polarized...the orange drops aren't either....sheeesh.. I hope reading another troubling post isn't starting to rub off on me :) So, you replaced all of your too huh, because thats the same thing Stephen from Trinity advises me to do also, as I love the tones other than that fartin bottom end..ol' Crusinhome suggested I try just changing just the one on the Bright which I will and hear how that sounds...thank you

I prefer .022uF coupling caps in all five places on a 5E3 also.

Here's another question guys..Working on the 1rst build, I had a bad coupling cap and robbed one from the 2nd parts kit....and now I've got the 2nd one entirely done except for that missing cap that i left out that goes to V2 pin 8...If I installed these new .022 coulpin cap in place of that orange drop .1 in that spot then another at V1 pin 6, what'll that do to the tone...Or I could put it say anotherway....this 2nd amp i'm working on is for my buddy whos a bit older and is fairly gentle on the strings as he doesn't beat on em like I do, but plays country, bit of blues.....will his tones be benefited from going to all these.022's... I love a nice deep bottom end tone but not boomin like it is... I've got the iron over there heating up now...

Yes to all .022uF coupling caps. If you want to experiment, begin with the first two caps from the right. Make them both .022uF. The third one is.022uF anyway. Changing the next two (to .022uF) is also beneficial, IMHO.

thanks Hackworth...let the soldering commence..
how can they do the same jobs with such a big difference in surface area..

Coupling cap calculator.
With a 1M volume pot, I would use a value of 680k with a tone control though, a 0.022uF cap has a roll off of less than 1dB at the open E of a guitar.
Hey, he has a new calculator for bass response for the PI/output stage.
With a 0.22uF cap and a concertina PI with 220k grid resistors, again less than 1dB at low E.

I'm not sure why Gods testing me like this but..... I Just plugged in #2 build and tested B+ voltage with no tubes installed and got 10-11, plugged in the Sovtek 5Y3 and checked it again....517VDC... I thought 425 was high on the other amp...but...
