Help with a silverface champ

[ericjwilliams]

I think I posted this in the wrong place originally, sorry about that im new here.

I have 2 silverface champs, one sounds very good and the other still sounds good but is more shrill sounding. The voltages vary a bit between the two amps. Could this amount of voltage variation cause that much difference in sound? If so how could I get more voltage out of the other Champ?

The caps are all original in both amps, they both have the same brand of tubes (I swapped them back and forth to see if it made a difference any way) they both have weber sig. alnico speakers (I tried swapping them as well)

here are my voltages

the good champ.

12ax7 6v6 5y3
pin. VDC pin VDC pin VDC
1 256 1 0 1 1
2 0 2 0 2 424
3 2 3 410 3 0
4 0 4 419 4 -6
5 261 5 0 5 0
6 0 6 0 6 -6
7 2 7 0 7 0
8 0 8 24 8 424

here is the cap can voltages I tried to make it how the can looks facing it
-- = 423
l = 413
-- = 391

the bad champ

12ax7 6v6 5y3
pin. VDC pin VDC pin VDC
1 255 1 0 1 0
2 0 2 0 2 399
3 2 3 386 3 0
4 0 4 395 4 -6
5 247 5 0 5 0
6 0 6 0 6 -5
7 2 7 0 7 0
8 0 8 23 8 399

cap can

-- = 400
l = 395
-- = 371

I just found this forum tonight and Im very happy to be a member. The tube chart will be very helpful in the future. I still pretty new to tube amps so go easy one me guys

Changing all of the Electrolytics including the can cap and the Cathode Resistor to Metal Film will put both of those back in great shape. Keep the old caps if you want to put it back original one day but E-Caps supposedly only last 15 to 20 years so they are way past their age and you will notice huge improvements in many areas of response and performance from those beauts.
