Does someone still make these?

Do you have specific locations that you need replacement for? MS caps are frequently found in tape decks. If the MS cap is in a tuner, I may be misidentifying the part. Seeing it in circuit will help clarify.

What is the general consensus of MUNDORF MLytic AG Power Caps for the Main Filter Caps?

Lovely luxury cap. 2x to 3x what a UCC or CD cap would cost. On my budget, I don't change out the big caps at all, unless they measure out of spec. For my forever amp, I'd look at Mundorf.

So, clearly MS are not motor start caps. Looked at the SM. Several caps are noted as 'MS'. May be it's a Yamaha nomenclature. The caps shown as MS are of all different sizes and values.

MS shall remain a mystery.

I used Mlytic AG MLGO series in both of my CX-1 control amps. I am absolutely happy with them and wouldn't hesitate to use the AG parts again where they fit. I wanted to use some in my MX-1 but unfortunately they do not fit.

Cheers,
James

What started me on the Mundorf was that it fits so much better, no board modifications needed.

I have been able to purchase the Mundorf 23,000uf 63v for less than $25 US each
