Technics SE-A5 re-cap

I'd say open it up. It's a bummer to get a recommendation, spend money and time to get the caps, then open up the case and realize you have a later Revision B of the board that uses different caps (usually smaller in physical size so the ones you bought won't fit mechanically). Been there done that 🙂
 
I am looking for the main capacitors 10000uF, 71V. Can someone direct me where to buy these or something that would fit and work even better ?

Given the age of the amp, most modern caps with similar ratings will be the same size or smaller.

Based on the service manual here: Technics SE-A5 Manual - Stereo Power Amplifier - HiFi Engine

The power supply caps seem to be axial lead parts, so more modern parts should physically fit in the space. The closest modern parts seem to be 10,000 uF @ 80 volts. The slightly higher voltage rating should not cause problems.

Here is a supplier with what seem to be relevant parts:

Aluminum Capacitors | Capacitors | DigiKey

Measure the size of the parts in your existing amp, and find some that are physically the same size or smaller.
 
@nicoch58,
Well, it's more like 10 to 12 screws on the top and 9 on the bottom, not just 4. 😕

@arnyk,
correct me if I am wrong, you probably meant to say Radial Leads. Yes, some newer vintage capacitors are smaller with same or very similar electrical parameters, no question.

My particular interest, perhaps my bad, I have not clearly ask for that are the mechanical dimensions of the main capacitors.

Height,
Diameter,
Pin Spacing,
Pin Diameter,
Number of Pins.

Or perhaps an original part number so I could look this up on the datasheet before shopping for these without having to open the old lady... 😀

Electrical parameters, I guess I buy the best available that fit the mechanical constraint. (perhaps higher rated voltage, higher rated capacitance, highest rated ripple current and lowest rated ESR).

Thanks anyone for trying to help 🙂
 
that's a lot of more work 😉
two pin , there is a standard on caps size...just take a look in post n°2 and post 7 all you need is there , pin to pin and if there is a space in the box , not a rocket science
ps if the pana HA is good for Pass ....

@nicoch58,

no kidding, I guess, Rocket Science is when one knows what to do before doing. 😉

Well the digikey Link you posted, shows some selected 4 Pin Capacitors. Yet you are telling me something about a two pin standard.

This is so confusing to me. 😕

So what is it then that Technics used in the A5 ? Two Pin or 4 Pin Capacitors ?

Thanks again, you have been of great help.
 
no difference cut the unused(support) or search for two pin panasonic T-HA series or alternative !
Why you want do that work better put the amp on hand of tech 😉

@nicoch58,

Tech ? You mean a handy crafted armed with electric tape and soldering grease ? 😀

If you want to have things done right, do them yourself.

More questions than answers...

I guess my question is too difficult to figure out on the forum. 😉
 
Here's how I recapped mine. Capacitor farm. Replaced the amp too. Mine was not working and I decided I'd rather replace the amp than fix it.
I was quite impressed with the quality of the SE-A5.
