Tweed Deluxe Clone sounds Thin and Weak Help Please!

[ElMambodelaMuerte]

Hi everybody,

I know this is really weird: somebody complaining about the lack of bass on a 5e3.
I just would like to ask you for some technical help and/or any thoughts or opinions on this. Any idea would be really helpful and appreciated.

The thing is that I got this 5e3 circuit clone that it is sounding not too nice to me right now. I would say that is very thin, with icepicky highs and a total lack of bass.
I was having a look on the components and could see the next differences in values with the original layout:

- The bright cap (the one between the volume and tone pot) is 300 pf instead of 500pf.
- The 12ay7's caps (pin 6 and pin 1) are 22nf instead 0.1 uf
- The electrolytics are 33uf, 22uf and 22uf from left to right.
- The Bias resistor is 2400J and 10w instead 250 ohm and 5w
- Both resistors on the 6v6s are 2.2k instead of 1k5
- Unfortunately, I cannot read the value of the 12ax7's caps (pin 6 and 8)

Based on this information, would you say that changing all the components to stock values iwould make the amp sounding fatter and nicer?
Or maybe the problem could be anywhere else?

Thank you so much in advance for your help, and sorry for my english (not my mother tongue)

Cheers!

Well... no, not entirely.
That setup will reduce the bass a few dB but not to the point that you are describing.
The 300pF cap will change the treble a bit but also the midrange.
I would think there is something else wired incorrectly on the tone pot or the volume pot next to it or the the tone pot is bad.
Can you take some decent pictures of the eyelet board, the wires to the three 1 meg pots and the capacitors on the tone pot?

Ok, I know the photo is really bad, but what do you think about that cable pointed in it?
Could that be the problem?

When I have time I will make some decent photos.

Thanks so much Bruce!

As you can see I removed the bright cap. It sounds better now, but still a little bit weird.

The wire you have drawn a circle around looks like it is not connected? Where does it go on the other end?

[ElMambodelaMuerte]

Yes, it is connected. I do not know where, but it is. The weird thing is that it shouldn't be there, that pin of the pot is already soldered to ground. Maybe another kind of mod? Any idea?
On the other hand, I realised as well about another wire soldered to the resistors between the v2's caps (the mustard ones). I cannot find anything similar on other 5e3 layouts.

That point... the common connection of the two 220K grid load resistors, is supposed to be at chassis ground. It looks like the builder used shielded cables to feed the power tube's grids and twisted the shielding together, grounding it there.
I don't see a brass plate for the ground system.
The volume pot ground wire could be a "homerun" to the preamp tube('s) cathode biasing resistor grounds. I've seen people do that too.

Yes better pictures would be even more helpful....
