Whenever i replace electrolytics (especially in the power supply), i like to add 1 or 2 Vishay Dale LVR-3 current shunt resistors, between 0.1 and 1 ohm, to maintain the small ESR, which the electrolytic had.

Ok but, can a film capacitor outlasts an electrolytic capacitor...it's a tempting decision but...
@petrosnemardos
Why not try it at 9,10,11,12'o clock listening volume ?
@PossibleAudio
I installed films rather than electrolytics during the pre-amp section rebuild on my Marantz 2245. I've read debates about this on AK forums and became torn.. Plus I came across one of your other older videos on capacitors and you had me convinced to keep with an electrolytic, if that's what was originally chosen by the engineers. It's good to know changing these from film to electrolytic won't make a difference in sound worth tackling. Saves me a lot of unnecessary work. WIMA Films it shall remain. Thanks!

I have a test for you Tony. i just recap my deck technics M270X and i could'n find any audio grade caps in 0.33uf and 0.68uf, so i put some Nichicon UVR & UPW caps in. I know the old caps are (now) panasonic MA serie, so i check the rimpel current for even or above of the MA-serie. The rest is a combination of rubycon and panasonic FR. Really, it sound great.
@jeep534h7
i am a old electroic technecin i really enjoying your videos. i am wondering if you equipment for sale??
@NickP333
I really enjoy what you’re doing here, Tony.

My personal Engineering Experience with audio fixing. Electrolytic Caps you should always use low ESR caps, because high frequencies can heat up the caps. It also extends the life of the Cap. As far as audio coupling caps I would always use ceramic ones if possible. In the old day they just did not have ceramic caps in high values like they do now, so you had to use a film cap. As far as noise in a circuit where possible I would always use ceramic caps.
@leaveempty5320
Surprised me. Thanks!
@jimboff2841
Tony, great great work. I would suggest that to start you should take only one output, run it into both channels of your comparator circuit to show how close the tests come out when looking at exactly the same signal.
@JCWise-sf9ww
Ok, good tests with Pink Noise. Did you do a total harmonic distortion & intermodulation distortion tests? What about driving the preamp into clipping? Consider the life expectancy of Film vs Electrolytic capacitors? After you do the other tests mentioned above, I could then tend to agree that there is hardly any noticeable audio difference.
@g.fortin3228
Pretty sweet thing to have two units to directly compare and having it controlled.. beautiful job. it's about time someone took the bull by the horns. Nice!
@keithtrauner1738
Awesome video, even for a relative novice. Easily understood, solid logical approach. Keep em coming!
@vsalasarcr
Greetings, fantastic video, thank you very much.
@Homer19521
Which CA2000 are you gonna keep??
@tonyb6173
Excellent, Thanks for clearing up that old bug bear. I've done that experiment with Film on one channel and electros in the other channel of a single amp. I couldn't tell any difference, but my ears are old to. Thanks for all the great videos, I've learned a lot from watching them
@Stelios.Posantzis
One note on this experiment: whatever the performance outcome, there is always the longevity and robustness aspect that needs to be taken into consideration too when choosing a component. The component must be up to the task under the given conditions that one designs for.
@Stelios.Posantzis
Awesome undertaking - must have been costly too! This must be a first on youtube or at least one of the few such videos on capacitor audio performance. It has to be the only such experiment (that I know of at least) of the comparison of two identical circuits with different components. The sophisticated equipment used to extend the breadth of the experiment is an extra plus. It's been so many years since Cyril Bateman's series of articles and praise is also due for resurfacing them.
@CovertCulvert
Very interesting comparison Tony. Never heard the one about the fly crap and pepper before! Just goes to show that if you're not careful you might learn something.
