re capping

@g_nakamoto... I apologize, I did not intend to have your thread go awry. 
 @kosst_amojan       Leaving an amp on all the time sounds better, period.
 Again,  I didn't turn it off for years upon years and caps measured at spec.  As, I'm sure that you know, caps with lower ESR should sound better, even thought spec'd at 105 degree parts vs 85 degree parts,  ESR was significantly lower.  
Yes,  it gets expensive and HOT in the summer.  I have a Class D amp that I made with Abletec modules that actually sounds quite good.  I ran on occasion and am using it now until I finish the old Sumo Nine,  but even while owning the Class D, I kept the Sumo Plugged in. 
The F5 is a nice sounding amp.  One of my best friends used it with Tektons and is now using a DIY version of the Aleph J. I wish that it was a bit more power, I'd give it a try.  I could use it with one set of my speakers, but it would be just ok with my other 2 sets.  I have a 12 inch 2 way with Heil AMT that is 4 ohm and 95db sensitivity, I have an MTM which is 4 ohm 88db sensitivity and I have a 10 inch 3 way that are 8 ohm 86db sensitivity.  My Sumo originally had 4, 10,000 mfd caps, it is now getting 8, 22,000 mfd.  With the beefed up power supply and a bit of re biasing now does around 80 to 8 and 160 to 4.  

thanks for all the comments. but my last question is, if my system sounds ok should i worry about 'anything'?

Worry? No. Just enjoy and if you do plan on keeping the amp then start planning for cap replacement for a later time.

just enjoy

So to this end of "knowing the circuit b4 recapping" .. I know the Counterpoint NPS 400 has been talked around the board a bit .. anyone know a tech who is proficient in Counterpoint? Mine will give a mild pop in one channel when powering up, no crackling or any other symptoms that I detect during play .. but am assuming caps are the issue? Built in 1996 btw.

When you recap a 30 year old amplifier do you change the big power supply caps or do you replace all of the circuit board caps?
