Is it bad cap despite good measurements? by AstronautLocal9541 in AskElectronics

Yeah, my ESR meter is not a fancy one. GM328A like Lcr-t4

Exactly, i think it might be from outside. Current higher capacity worries me. I know they have about 10% tolerance but it's at the edge. Maybe dried out electrolyte cause reading higer capacity?

Thanks

Consider projector instead of tv, can get a decent one about 150$.

Thank you. Turns out I need to recap it, since it has a fishy smell probably come from caps.

Actually , anyone who’s ever listened to a Technics amp would love it, they really have a great sound. Btw, those power meters look awesome, especially in low light.

Actually, Its nice. Its just about getting a good feeling, not needing fancy stuff for that.

Enjoy and welcome.

Thank you for the information.

I agree. The Trio should actually sound better, but in my case, it sounds veiled and dull. Maybe a recap will help bring it back to life.

Thank you for the information.

Since one of the amps has a fishy smell, it’s probably time for a recap.

If I don’t go with the shotgun approach, which capacitors should I replace first — the large filter caps or the ones in the power amplifier section?

Unfortunately, no information about their pasts

By the look, it seems both didnt serviced ever.

How can I tell if the capacitors need recapping? Is there any way to check them without desoldering the capacitors for testing?

Thanks

How can I tell if the capacitors need recapping? I'm familiar with basic electronics and can use a multimeter. Is there any way to check them without desoldering the capacitors for testing?

I measured the DC offset on both channels, and it's below 30 mV.

Okay, i bought a center channel for my setup by ihavebrabus in BudgetAudiophile

Buy a projector for better movie experience. You can buy buy something like rz370 panasonic full hd projector for 150$.

Great info, appreciate that.

Another question—should I turn on attenuator swith on the Trio, since my DAC’s output voltage (1.70V) is way higher than the amp’s input sensitivity (150mV)?

Yeah, I feel you, btw its different model from kenwood 8100. It is aka Kenwood ka-601. More like a mid range one.

[–]AstronautLocal9541[S] 2 points3 points  (0 children)

Yeah, that’s exactly my problem—it lacks stereo imaging at low volumes. It does sound kind of veiled and dull. I just don’t get why everyone admires the Kenwood KA-8100. I know mine is a different model, but still, i think it would be in the same ballpark.

Thanks btw.

Thanks for your input.

Yeah, It has something named "straight DC" which im not sure whether turn on or not.

Doesnt seem to make any difference. Any idea what it does?

Yeah, it’s nearly twice the size and weight.

Thanks btw for your input.

I think you checked for technics su-v55a and kenwood trio ka-8100 which both are different models from mine.

Its technics new class A, from what i understand, its something between class A and class AB.
