88.19.142.194
I am thinking of replacing the old, cheap 80V / 10000uF smoothing capacitors of my power amp with Panasonic caps from the TS-HA series (I have read excellent reports from the users of these 'snap-in'-type caps).
However, the maximum capacitance value offered by PANASONIC in the 80 V range is 6800uF.

Given the fact that the secondaries of the power transformer of my power amp measure *45* V, could I get into trouble if I replace the actual *80* V /10000 uF smoothing caps with *63* V / 10000uF caps?
Thanks in advance for any input.
Follow Ups:
For safety reason, you need to use 80V rated cap.
63V cap is too low.
Meg, these caps are not directly in the signal path.
Good is probably good enough. You don't need Lexus caps.
Better than stock for sure, but at some point other parts of the amp will become the limit.
Just for example, are all the resistors a good film part (thick or thin) or are there some carbon resistors? Are the rest of the caps film caps, or oil/paper, or some inferior make?
Too much is never enough
There are no carbon resistors anywhere in the circuit. All of them are metal film.
I am thinking of replacing some of these with VISHAY S102 (bulk metal foil), but I wonder whether this would be of some benefit.
Meglo,
only you can do the cost / benefit. If your current (no pun intended) resistors were some cheesy carbon units, than yeah, a complete redo with a good film resistor could help. Only those in the signal path to be replaced? Caps, too, than. Same proviso. If you have some real nice caps in a premium amp, than the change to 'better' caps may not net you what you intend.
If you went thru the whole thing cost-no-object, would you have the equivalent of say.....2x the original cost of your amp at retail? You are also limited by the original design. The amp was voiced with what's in it now and built to sell for X #of $$.
How expensive was the amp in the first place? Is is just possible you are up against the wall here?
How much would you put into the upgrade? Put some arbitrary value on your time, add in all parts and the resale value of the amp as it now sits. Could you replace it with substantially better for that much?

Meg,
you did not mention which type or brand your OE caps were. If they are computer grade, I doubt they need to be replaced. And the snap mount panasonics are not equiv. You would need to move up to the computer grade Panasonics.
If you are concerned with the sound, you would be better off spending your time looking/testing bypass caps to add to your existing filter caps. You will get a much bigger bang for the buck.

In the PANASONIC catalog, I have seen that they also have a cap series (the TS-UQ series) with a *10000* uF model in the *80* V range (part number: EETUQ1K103LA).

My doubt is: Is the TS-UQ series of PANASONIC as good as the TS-HA series?
Don't do it. If I'm correct the 45v rms is about 63v PEAK which exceeds the proposed value of the new caps. the original 80v rating is as LOW as you should go.
What's the problem you are trying to 'fix'?
