Unless they are really old stock, I dont see why there would be an issue.
There are some others who have used them. I haven't heard anything negative.

great they were not cheep.do you no what low esr is

equivalent series resistance, ie internal resistance of the cap. How fast it will charge and discharge.

ESR isn't that critical on those large main caps. You're not dealing with a switch mode supply. The most important aspects here are the voltage and capacitance.

so this can be a problem

No, I'm saying what you bought should be fine. In this case dont
be too concerned about ESR specs.

shwwoo thx

Good choice

i can't wait got it all recaped just need the filters

 

[denny9969]

i wonder should i change the output transistors or is that in vain.can you get the same ones

Probably best to just replace the micas and renew the heat sink grease if they are currently working OK. Be sure that the grease you use is non-conductive.

I've had a pair of the Adcom 22kuf big blue caps in my SX-1050 for over a year now, still working well!

ok sounds good will do thx

 

[denny9969]

If the relay is closing you can use the speaker terminals.

yea at first it took abount 10seconds then click.vr2 was all over the place now 65.1 vr1 at 65 looking good i think i am now on to bias. i am very confused about bias what do i need to do thx
