Not that hard: http://www.ebay.com/sch/i.html?_from=R40&_sacat=0&_nkw=k73-16+0.47uF&LH_PrefLoc=2&_sop=15

Get the 71V Kenwood, the 75V is too fat. Denon is the best you can get.

Soviet film capacitors can be found here in Moscow =)

 

I wrote about the two types of electrolytic capacitors.

 

Thanks for clarifying.

Tell me please.
You mean it?

 

Something else is needed?

Yes, that's what I mean. All you need is in the "Third Mod".

post #395 of 400

6 x OPA1602AIDR (or OPA1602AID)

5 x K73-16 0.47uf 63V (or K73-11 63V)

1 x Elna Kenwood 4700uF 75V (or Elna Kenwood 4700uF 71V)

2 x Elna Denon 10000uF 50V

 

What else do I need to buy?

Obviously short circuit. Can be small, hard to detect.

Or misplaced mica insulator(s), solder drop, metal fragment, screw between the pins of the TDA AMP. Component installed the wrong way, left out, damaged, bad solder joint. Long list of possibilities....

If you find the mistake, you may need new resistors (or worst, regulators too) to make the system work again.

Hello and thank you for your angagemang!
I've checked and all components are correctly fitted
Since
I have found a bad solder on a cable that goes to the right channel filter capacitors fixture that includes:

10000uF63V Elna for Audio
1000uF63V Elna
220uF63V Elna
100uF63V Elna
10uF63V Ero MKT
4,7uF63V Ero MKC
2.2uF100V Ero MKT
1uF63V Wima FMD
0.22uF 63V MKT

 But wonder if it can burn
both R21 and R22 resistor.

R21 to steady done "little" hole in the PCB
R22 is only burns

More info
Changed blown Logitech speakers with sub Pioneer TS-W261D4 ​​is two spolig 4ohm and brygat out between the plus and minus!

PreAmp panel I have changed ceramic capacitors with K73-160.22uF 160V is it ok?
The residue was used
1 pc. 4700UF 63V ELNA KENWOOD
13 pcs. 22UF 50V Elna Silmic II
6st. 47uF 50V Elna Silmic II
1st. 10uF 16V Elna Silmic II
12st. 0.22uF 63V MKT
1st. 1uF63V Wima MKS

2st

TEXAS INSTRUMENTS - OPA1602AID - OP AMP, AUDIO, BIPOLAR, 8MS...

 

Kontrol pod, I purchased components not modat than
It was not cheap can not stop now and throw everything

SINCERELY

"But wonder if it can burn both R21 and R22 resistor." When the filter capacitors have a bad contact you get hum, but If it was a hot ground problem..... I just do not know how the regulators behave without it.

"K73-16 0.22uF 160V is it ok?" It is.
